==================================================
 
:rem:`|||:sec:|||`\ Installation
 
==================================================
 

	
 
#. Copy the program anywhere on your harddrive.
 

	
 
#. Change alias `/vacation` in `lib/ws-vacation.conf.in`, if desired.
 

	
 
#. Execute the following commands (as user) to create the run-time files:
 

	
 
   >>> make clean
 
   >>> make
 

	
 
   This substitutes the installation directory in the necessary places.
 

	
 
#. Copy `lib/ws-vacation.conf` to `/etc/apache2/conf.d/`.
 

	
 
#. Reload the Apache server:
 

	
 
   >>> rcapache2 reload.
 

	
 
#. The sudo(1) setup allows the apache server to execute vacation(1)
 
   as any user (except root) without a password. This is activated by
 
   copying the file `lib/ws-vacation-sudo` into the directory
 
   `/etc/sudoers.d` (ubuntu):
 

	
 
   >>> cp lib/ws-vacation-sudo /etc/sudoers.d/ws-vacation-sudo
 
   >>> chmod 0440 /etc/sudoers.d/ws-vacation-sudo
 

	
 
   or by appending it to the file `/etc/sudoers` (older SuSE):
 

	
 
   >>> cat lib/ws-vacation-sudo >>/etc/sudoers
 

	
 
==================================================
 
:rem:`|||:sec:|||`\ User Management
 
==================================================
 

	
 
The file `lib/.htpasswd` can be created by the regular means.
 

	
 
An automated script is available that creates the password database
 
from the system shadow(8) database. Just change into directory `lib`
 
and execute (as `root`):
 

	
 
>>> php gen_htpasswd.php
 

	
 
.. note:: If new users are created in the system, this step must be
 
   repeated to update the `.htpasswd` file.
 

	
 
:rem:`abstand`
 

	
 
==================================================
 
:rem:`|||:sec:|||`\ Configuration
 
==================================================
 

	
 
The file `lib/config.php` contains the basic configuration data.
 

	
 
It is possible to fine-tune the standard user selection with:
 

	
 
* $ALLOWED_USERS: users who are always accepted (if present in `/etc/passwd`).
 
* $INVALID_USERS: invalid users, which are always ignored.
 
* $ADMIN_USERS: administrators.
 

	
 
The file `lib/language.php` contains language specific translation and
 
also the default vacation(1) message text.
 

	
 
The HTML header and footer can be modified in `lib/templates.php`.

                    GNU GENERAL PUBLIC LICENSE
 
                       Version 3, 29 June 2007
 

	
 
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
 
 Everyone is permitted to copy and distribute verbatim copies
 
 of this license document, but changing it is not allowed.
 

	
 
                            Preamble
 

	
 
  The GNU General Public License is a free, copyleft license for
 
software and other kinds of works.
 

	
 
  The licenses for most software and other practical works are designed
 
to take away your freedom to share and change the works.  By contrast,
 
the GNU General Public License is intended to guarantee your freedom to
 
share and change all versions of a program--to make sure it remains free
 
software for all its users.  We, the Free Software Foundation, use the
 
GNU General Public License for most of our software; it applies also to
 
any other work released this way by its authors.  You can apply it to
 
your programs, too.
 

	
 
  When we speak of free software, we are referring to freedom, not
 
price.  Our General Public Licenses are designed to make sure that you
 
have the freedom to distribute copies of free software (and charge for
 
them if you wish), that you receive source code or can get it if you
 
want it, that you can change the software or use pieces of it in new
 
free programs, and that you know you can do these things.
 

	
 
  To protect your rights, we need to prevent others from denying you
 
these rights or asking you to surrender the rights.  Therefore, you have
 
certain responsibilities if you distribute copies of the software, or if
 
you modify it: responsibilities to respect the freedom of others.
 

	
 
  For example, if you distribute copies of such a program, whether
 
gratis or for a fee, you must pass on to the recipients the same
 
freedoms that you received.  You must make sure that they, too, receive
 
or can get the source code.  And you must show them these terms so they
 
know their rights.
 

	
 
  Developers that use the GNU GPL protect your rights with two steps:
 
(1) assert copyright on the software, and (2) offer you this License
 
giving you legal permission to copy, distribute and/or modify it.
 

	
 
  For the developers' and authors' protection, the GPL clearly explains
 
that there is no warranty for this free software.  For both users' and
 
authors' sake, the GPL requires that modified versions be marked as
 
changed, so that their problems will not be attributed erroneously to
 
authors of previous versions.
 

	
 
  Some devices are designed to deny users access to install or run
 
modified versions of the software inside them, although the manufacturer
 
can do so.  This is fundamentally incompatible with the aim of
 
protecting users' freedom to change the software.  The systematic
 
pattern of such abuse occurs in the area of products for individuals to
 
use, which is precisely where it is most unacceptable.  Therefore, we
 
have designed this version of the GPL to prohibit the practice for those
 
products.  If such problems arise substantially in other domains, we
 
stand ready to extend this provision to those domains in future versions
 
of the GPL, as needed to protect the freedom of users.
 

	
 
  Finally, every program is threatened constantly by software patents.
 
States should not allow patents to restrict development and use of
 
software on general-purpose computers, but in those that do, we wish to
 
avoid the special danger that patents applied to a free program could
 
make it effectively proprietary.  To prevent this, the GPL assures that
 
patents cannot be used to render the program non-free.
 

	
 
  The precise terms and conditions for copying, distribution and
 
modification follow.
 

	
 
                       TERMS AND CONDITIONS
 

	
 
  0. Definitions.
 

	
 
  "This License" refers to version 3 of the GNU General Public License.
 

	
 
  "Copyright" also means copyright-like laws that apply to other kinds of
 
works, such as semiconductor masks.
 

	
 
  "The Program" refers to any copyrightable work licensed under this
 
License.  Each licensee is addressed as "you".  "Licensees" and
 
"recipients" may be individuals or organizations.
 

	
 
  To "modify" a work means to copy from or adapt all or part of the work
 
in a fashion requiring copyright permission, other than the making of an
 
exact copy.  The resulting work is called a "modified version" of the
 
earlier work or a work "based on" the earlier work.
 

	
 
  A "covered work" means either the unmodified Program or a work based
 
on the Program.
 

	
 
  To "propagate" a work means to do anything with it that, without
 
permission, would make you directly or secondarily liable for
 
infringement under applicable copyright law, except executing it on a
 
computer or modifying a private copy.  Propagation includes copying,
 
distribution (with or without modification), making available to the
 
public, and in some countries other activities as well.
 

	
 
  To "convey" a work means any kind of propagation that enables other
 
parties to make or receive copies.  Mere interaction with a user through
 
a computer network, with no transfer of a copy, is not conveying.
 

	
 
  An interactive user interface displays "Appropriate Legal Notices"
 
to the extent that it includes a convenient and prominently visible
 
feature that (1) displays an appropriate copyright notice, and (2)
 
tells the user that there is no warranty for the work (except to the
 
extent that warranties are provided), that licensees may convey the
 
work under this License, and how to view a copy of this License.  If
 
the interface presents a list of user commands or options, such as a
 
menu, a prominent item in the list meets this criterion.
 

	
 
  1. Source Code.
 

	
 
  The "source code" for a work means the preferred form of the work
 
for making modifications to it.  "Object code" means any non-source
 
form of a work.
 

	
 
  A "Standard Interface" means an interface that either is an official
 
standard defined by a recognized standards body, or, in the case of
 
interfaces specified for a particular programming language, one that
 
is widely used among developers working in that language.
 

	
 
  The "System Libraries" of an executable work include anything, other
 
than the work as a whole, that (a) is included in the normal form of
 
packaging a Major Component, but which is not part of that Major
 
Component, and (b) serves only to enable use of the work with that
 
Major Component, or to implement a Standard Interface for which an
 
implementation is available to the public in source code form.  A
 
"Major Component", in this context, means a major essential component
 
(kernel, window system, and so on) of the specific operating system
 
(if any) on which the executable work runs, or a compiler used to
 
produce the work, or an object code interpreter used to run it.
 

	
 
  The "Corresponding Source" for a work in object code form means all
 
the source code needed to generate, install, and (for an executable
 
work) run the object code and to modify the work, including scripts to
 
control those activities.  However, it does not include the work's
 
System Libraries, or general-purpose tools or generally available free
 
programs which are used unmodified in performing those activities but
 
which are not part of the work.  For example, Corresponding Source
 
includes interface definition files associated with source files for
 
the work, and the source code for shared libraries and dynamically
 
linked subprograms that the work is specifically designed to require,
 
such as by intimate data communication or control flow between those
 
subprograms and other parts of the work.
 

	
 
  The Corresponding Source need not include anything that users
 
can regenerate automatically from other parts of the Corresponding
 
Source.
 

	
 
  The Corresponding Source for a work in source code form is that
 
same work.
 

	
 
  2. Basic Permissions.
 

	
 
  All rights granted under this License are granted for the term of
 
copyright on the Program, and are irrevocable provided the stated
 
conditions are met.  This License explicitly affirms your unlimited
 
permission to run the unmodified Program.  The output from running a
 
covered work is covered by this License only if the output, given its
 
content, constitutes a covered work.  This License acknowledges your
 
rights of fair use or other equivalent, as provided by copyright law.
 

	
 
  You may make, run and propagate covered works that you do not
 
convey, without conditions so long as your license otherwise remains
 
in force.  You may convey covered works to others for the sole purpose
 
of having them make modifications exclusively for you, or provide you
 
with facilities for running those works, provided that you comply with
 
the terms of this License in conveying all material for which you do
 
not control copyright.  Those thus making or running the covered works
 
for you must do so exclusively on your behalf, under your direction
 
and control, on terms that prohibit them from making any copies of
 
your copyrighted material outside their relationship with you.
 

	
 
  Conveying under any other circumstances is permitted solely under
 
the conditions stated below.  Sublicensing is not allowed; section 10
 
makes it unnecessary.
 

	
 
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
 

	
 
  No covered work shall be deemed part of an effective technological
 
measure under any applicable law fulfilling obligations under article
 
11 of the WIPO copyright treaty adopted on 20 December 1996, or
 
similar laws prohibiting or restricting circumvention of such
 
measures.
 

	
 
  When you convey a covered work, you waive any legal power to forbid
 
circumvention of technological measures to the extent such circumvention
 
is effected by exercising rights under this License with respect to
 
the covered work, and you disclaim any intention to limit operation or
 
modification of the work as a means of enforcing, against the work's
 
users, your or third parties' legal rights to forbid circumvention of
 
technological measures.
 

	
 
  4. Conveying Verbatim Copies.
 

	
 
  You may convey verbatim copies of the Program's source code as you
 
receive it, in any medium, provided that you conspicuously and
 
appropriately publish on each copy an appropriate copyright notice;
 
keep intact all notices stating that this License and any
 
non-permissive terms added in accord with section 7 apply to the code;
 
keep intact all notices of the absence of any warranty; and give all
 
recipients a copy of this License along with the Program.
 

	
 
  You may charge any price or no price for each copy that you convey,
 
and you may offer support or warranty protection for a fee.
 

	
 
  5. Conveying Modified Source Versions.
 

	
 
  You may convey a work based on the Program, or the modifications to
 
produce it from the Program, in the form of source code under the
 
terms of section 4, provided that you also meet all of these conditions:
 

	
 
    a) The work must carry prominent notices stating that you modified
 
    it, and giving a relevant date.
 

	
 
    b) The work must carry prominent notices stating that it is
 
    released under this License and any conditions added under section
 
    7.  This requirement modifies the requirement in section 4 to
 
    "keep intact all notices".
 

	
 
    c) You must license the entire work, as a whole, under this
 
    License to anyone who comes into possession of a copy.  This
 
    License will therefore apply, along with any applicable section 7
 
    additional terms, to the whole of the work, and all its parts,
 
    regardless of how they are packaged.  This License gives no
 
    permission to license the work in any other way, but it does not
 
    invalidate such permission if you have separately received it.
 

	
 
    d) If the work has interactive user interfaces, each must display
 
    Appropriate Legal Notices; however, if the Program has interactive
 
    interfaces that do not display Appropriate Legal Notices, your
 
    work need not make them do so.
 

	
 
  A compilation of a covered work with other separate and independent
 
works, which are not by their nature extensions of the covered work,
 
and which are not combined with it such as to form a larger program,
 
in or on a volume of a storage or distribution medium, is called an
 
"aggregate" if the compilation and its resulting copyright are not
 
used to limit the access or legal rights of the compilation's users
 
beyond what the individual works permit.  Inclusion of a covered work
 
in an aggregate does not cause this License to apply to the other
 
parts of the aggregate.
 

	
 
  6. Conveying Non-Source Forms.
 

	
 
  You may convey a covered work in object code form under the terms
 
of sections 4 and 5, provided that you also convey the
 
machine-readable Corresponding Source under the terms of this License,
 
in one of these ways:
 

	
 
    a) Convey the object code in, or embodied in, a physical product
 
    (including a physical distribution medium), accompanied by the
 
    Corresponding Source fixed on a durable physical medium
 
    customarily used for software interchange.
 

	
 
    b) Convey the object code in, or embodied in, a physical product
 
    (including a physical distribution medium), accompanied by a
 
    written offer, valid for at least three years and valid for as
 
    long as you offer spare parts or customer support for that product
 
    model, to give anyone who possesses the object code either (1) a
 
    copy of the Corresponding Source for all the software in the
 
    product that is covered by this License, on a durable physical
 
    medium customarily used for software interchange, for a price no
 
    more than your reasonable cost of physically performing this
 
    conveying of source, or (2) access to copy the
 
    Corresponding Source from a network server at no charge.
 

	
 
    c) Convey individual copies of the object code with a copy of the
 
    written offer to provide the Corresponding Source.  This
 
    alternative is allowed only occasionally and noncommercially, and
 
    only if you received the object code with such an offer, in accord
 
    with subsection 6b.
 

	
 
    d) Convey the object code by offering access from a designated
 
    place (gratis or for a charge), and offer equivalent access to the
 
    Corresponding Source in the same way through the same place at no
 
    further charge.  You need not require recipients to copy the
 
    Corresponding Source along with the object code.  If the place to
 
    copy the object code is a network server, the Corresponding Source
 
    may be on a different server (operated by you or a third party)
 
    that supports equivalent copying facilities, provided you maintain
 
    clear directions next to the object code saying where to find the
 
    Corresponding Source.  Regardless of what server hosts the
 
    Corresponding Source, you remain obligated to ensure that it is
 
    available for as long as needed to satisfy these requirements.
 

	
 
    e) Convey the object code using peer-to-peer transmission, provided
 
    you inform other peers where the object code and Corresponding
 
    Source of the work are being offered to the general public at no
 
    charge under subsection 6d.
 

	
 
  A separable portion of the object code, whose source code is excluded
 
from the Corresponding Source as a System Library, need not be
 
included in conveying the object code work.
 

	
 
  A "User Product" is either (1) a "consumer product", which means any
 
tangible personal property which is normally used for personal, family,
 
or household purposes, or (2) anything designed or sold for incorporation
 
into a dwelling.  In determining whether a product is a consumer product,
 
doubtful cases shall be resolved in favor of coverage.  For a particular
 
product received by a particular user, "normally used" refers to a
 
typical or common use of that class of product, regardless of the status
 
of the particular user or of the way in which the particular user
 
actually uses, or expects or is expected to use, the product.  A product
 
is a consumer product regardless of whether the product has substantial
 
commercial, industrial or non-consumer uses, unless such uses represent
 
the only significant mode of use of the product.
 

	
 
  "Installation Information" for a User Product means any methods,
 
procedures, authorization keys, or other information required to install
 
and execute modified versions of a covered work in that User Product from
 
a modified version of its Corresponding Source.  The information must
 
suffice to ensure that the continued functioning of the modified object
 
code is in no case prevented or interfered with solely because
 
modification has been made.
 

	
 
  If you convey an object code work under this section in, or with, or
 
specifically for use in, a User Product, and the conveying occurs as
 
part of a transaction in which the right of possession and use of the
 
User Product is transferred to the recipient in perpetuity or for a
 
fixed term (regardless of how the transaction is characterized), the
 
Corresponding Source conveyed under this section must be accompanied
 
by the Installation Information.  But this requirement does not apply
 
if neither you nor any third party retains the ability to install
 
modified object code on the User Product (for example, the work has
 
been installed in ROM).
 

	
 
  The requirement to provide Installation Information does not include a
 
requirement to continue to provide support service, warranty, or updates
 
for a work that has been modified or installed by the recipient, or for
 
the User Product in which it has been modified or installed.  Access to a
 
network may be denied when the modification itself materially and
 
adversely affects the operation of the network or violates the rules and
 
protocols for communication across the network.
 

	
 
  Corresponding Source conveyed, and Installation Information provided,
 
in accord with this section must be in a format that is publicly
 
documented (and with an implementation available to the public in
 
source code form), and must require no special password or key for
 
unpacking, reading or copying.
 

	
 
  7. Additional Terms.
 

	
 
  "Additional permissions" are terms that supplement the terms of this
 
License by making exceptions from one or more of its conditions.
 
Additional permissions that are applicable to the entire Program shall
 
be treated as though they were included in this License, to the extent
 
that they are valid under applicable law.  If additional permissions
 
apply only to part of the Program, that part may be used separately
 
under those permissions, but the entire Program remains governed by
 
this License without regard to the additional permissions.
 

	
 
  When you convey a copy of a covered work, you may at your option
 
remove any additional permissions from that copy, or from any part of
 
it.  (Additional permissions may be written to require their own
 
removal in certain cases when you modify the work.)  You may place
 
additional permissions on material, added by you to a covered work,
 
for which you have or can give appropriate copyright permission.
 

	
 
  Notwithstanding any other provision of this License, for material you
 
add to a covered work, you may (if authorized by the copyright holders of
 
that material) supplement the terms of this License with terms:
 

	
 
    a) Disclaiming warranty or limiting liability differently from the
 
    terms of sections 15 and 16 of this License; or
 

	
 
    b) Requiring preservation of specified reasonable legal notices or
 
    author attributions in that material or in the Appropriate Legal
 
    Notices displayed by works containing it; or
 

	
 
    c) Prohibiting misrepresentation of the origin of that material, or
 
    requiring that modified versions of such material be marked in
 
    reasonable ways as different from the original version; or
 

	
 
    d) Limiting the use for publicity purposes of names of licensors or
 
    authors of the material; or
 

	
 
    e) Declining to grant rights under trademark law for use of some
 
    trade names, trademarks, or service marks; or
 

	
 
    f) Requiring indemnification of licensors and authors of that
 
    material by anyone who conveys the material (or modified versions of
 
    it) with contractual assumptions of liability to the recipient, for
 
    any liability that these contractual assumptions directly impose on
 
    those licensors and authors.
 

	
 
  All other non-permissive additional terms are considered "further
 
restrictions" within the meaning of section 10.  If the Program as you
 
received it, or any part of it, contains a notice stating that it is
 
governed by this License along with a term that is a further
 
restriction, you may remove that term.  If a license document contains
 
a further restriction but permits relicensing or conveying under this
 
License, you may add to a covered work material governed by the terms
 
of that license document, provided that the further restriction does
 
not survive such relicensing or conveying.
 

	
 
  If you add terms to a covered work in accord with this section, you
 
must place, in the relevant source files, a statement of the
 
additional terms that apply to those files, or a notice indicating
 
where to find the applicable terms.
 

	
 
  Additional terms, permissive or non-permissive, may be stated in the
 
form of a separately written license, or stated as exceptions;
 
the above requirements apply either way.
 

	
 
  8. Termination.
 

	
 
  You may not propagate or modify a covered work except as expressly
 
provided under this License.  Any attempt otherwise to propagate or
 
modify it is void, and will automatically terminate your rights under
 
this License (including any patent licenses granted under the third
 
paragraph of section 11).
 

	
 
  However, if you cease all violation of this License, then your
 
license from a particular copyright holder is reinstated (a)
 
provisionally, unless and until the copyright holder explicitly and
 
finally terminates your license, and (b) permanently, if the copyright
 
holder fails to notify you of the violation by some reasonable means
 
prior to 60 days after the cessation.
 

	
 
  Moreover, your license from a particular copyright holder is
 
reinstated permanently if the copyright holder notifies you of the
 
violation by some reasonable means, this is the first time you have
 
received notice of violation of this License (for any work) from that
 
copyright holder, and you cure the violation prior to 30 days after
 
your receipt of the notice.
 

	
 
  Termination of your rights under this section does not terminate the
 
licenses of parties who have received copies or rights from you under
 
this License.  If your rights have been terminated and not permanently
 
reinstated, you do not qualify to receive new licenses for the same
 
material under section 10.
 

	
 
  9. Acceptance Not Required for Having Copies.
 

	
 
  You are not required to accept this License in order to receive or
 
run a copy of the Program.  Ancillary propagation of a covered work
 
occurring solely as a consequence of using peer-to-peer transmission
 
to receive a copy likewise does not require acceptance.  However,
 
nothing other than this License grants you permission to propagate or
 
modify any covered work.  These actions infringe copyright if you do
 
not accept this License.  Therefore, by modifying or propagating a
 
covered work, you indicate your acceptance of this License to do so.
 

	
 
  10. Automatic Licensing of Downstream Recipients.
 

	
 
  Each time you convey a covered work, the recipient automatically
 
receives a license from the original licensors, to run, modify and
 
propagate that work, subject to this License.  You are not responsible
 
for enforcing compliance by third parties with this License.
 

	
 
  An "entity transaction" is a transaction transferring control of an
 
organization, or substantially all assets of one, or subdividing an
 
organization, or merging organizations.  If propagation of a covered
 
work results from an entity transaction, each party to that
 
transaction who receives a copy of the work also receives whatever
 
licenses to the work the party's predecessor in interest had or could
 
give under the previous paragraph, plus a right to possession of the
 
Corresponding Source of the work from the predecessor in interest, if
 
the predecessor has it or can get it with reasonable efforts.
 

	
 
  You may not impose any further restrictions on the exercise of the
 
rights granted or affirmed under this License.  For example, you may
 
not impose a license fee, royalty, or other charge for exercise of
 
rights granted under this License, and you may not initiate litigation
 
(including a cross-claim or counterclaim in a lawsuit) alleging that
 
any patent claim is infringed by making, using, selling, offering for
 
sale, or importing the Program or any portion of it.
 

	
 
  11. Patents.
 

	
 
  A "contributor" is a copyright holder who authorizes use under this
 
License of the Program or a work on which the Program is based.  The
 
work thus licensed is called the contributor's "contributor version".
 

	
 
  A contributor's "essential patent claims" are all patent claims
 
owned or controlled by the contributor, whether already acquired or
 
hereafter acquired, that would be infringed by some manner, permitted
 
by this License, of making, using, or selling its contributor version,
 
but do not include claims that would be infringed only as a
 
consequence of further modification of the contributor version.  For
 
purposes of this definition, "control" includes the right to grant
 
patent sublicenses in a manner consistent with the requirements of
 
this License.
 

	
 
  Each contributor grants you a non-exclusive, worldwide, royalty-free
 
patent license under the contributor's essential patent claims, to
 
make, use, sell, offer for sale, import and otherwise run, modify and
 
propagate the contents of its contributor version.
 

	
 
  In the following three paragraphs, a "patent license" is any express
 
agreement or commitment, however denominated, not to enforce a patent
 
(such as an express permission to practice a patent or covenant not to
 
sue for patent infringement).  To "grant" such a patent license to a
 
party means to make such an agreement or commitment not to enforce a
 
patent against the party.
 

	
 
  If you convey a covered work, knowingly relying on a patent license,
 
and the Corresponding Source of the work is not available for anyone
 
to copy, free of charge and under the terms of this License, through a
 
publicly available network server or other readily accessible means,
 
then you must either (1) cause the Corresponding Source to be so
 
available, or (2) arrange to deprive yourself of the benefit of the
 
patent license for this particular work, or (3) arrange, in a manner
 
consistent with the requirements of this License, to extend the patent
 
license to downstream recipients.  "Knowingly relying" means you have
 
actual knowledge that, but for the patent license, your conveying the
 
covered work in a country, or your recipient's use of the covered work
 
in a country, would infringe one or more identifiable patents in that
 
country that you have reason to believe are valid.
 

	
 
  If, pursuant to or in connection with a single transaction or
 
arrangement, you convey, or propagate by procuring conveyance of, a
 
covered work, and grant a patent license to some of the parties
 
receiving the covered work authorizing them to use, propagate, modify
 
or convey a specific copy of the covered work, then the patent license
 
you grant is automatically extended to all recipients of the covered
 
work and works based on it.
 

	
 
  A patent license is "discriminatory" if it does not include within
 
the scope of its coverage, prohibits the exercise of, or is
 
conditioned on the non-exercise of one or more of the rights that are
 
specifically granted under this License.  You may not convey a covered
 
work if you are a party to an arrangement with a third party that is
 
in the business of distributing software, under which you make payment
 
to the third party based on the extent of your activity of conveying
 
the work, and under which the third party grants, to any of the
 
parties who would receive the covered work from you, a discriminatory
 
patent license (a) in connection with copies of the covered work
 
conveyed by you (or copies made from those copies), or (b) primarily
 
for and in connection with specific products or compilations that
 
contain the covered work, unless you entered into that arrangement,
 
or that patent license was granted, prior to 28 March 2007.
 

	
 
  Nothing in this License shall be construed as excluding or limiting
 
any implied license or other defenses to infringement that may
 
otherwise be available to you under applicable patent law.
 

	
 
  12. No Surrender of Others' Freedom.
 

	
 
  If conditions are imposed on you (whether by court order, agreement or
 
otherwise) that contradict the conditions of this License, they do not
 
excuse you from the conditions of this License.  If you cannot convey a
 
covered work so as to satisfy simultaneously your obligations under this
 
License and any other pertinent obligations, then as a consequence you may
 
not convey it at all.  For example, if you agree to terms that obligate you
 
to collect a royalty for further conveying from those to whom you convey
 
the Program, the only way you could satisfy both those terms and this
 
License would be to refrain entirely from conveying the Program.
 

	
 
  13. Use with the GNU Affero General Public License.
 

	
 
  Notwithstanding any other provision of this License, you have
 
permission to link or combine any covered work with a work licensed
 
under version 3 of the GNU Affero General Public License into a single
 
combined work, and to convey the resulting work.  The terms of this
 
License will continue to apply to the part which is the covered work,
 
but the special requirements of the GNU Affero General Public License,
 
section 13, concerning interaction through a network will apply to the
 
combination as such.
 

	
 
  14. Revised Versions of this License.
 

	
 
  The Free Software Foundation may publish revised and/or new versions of
 
the GNU General Public License from time to time.  Such new versions will
 
be similar in spirit to the present version, but may differ in detail to
 
address new problems or concerns.
 

	
 
  Each version is given a distinguishing version number.  If the
 
Program specifies that a certain numbered version of the GNU General
 
Public License "or any later version" applies to it, you have the
 
option of following the terms and conditions either of that numbered
 
version or of any later version published by the Free Software
 
Foundation.  If the Program does not specify a version number of the
 
GNU General Public License, you may choose any version ever published
 
by the Free Software Foundation.
 

	
 
  If the Program specifies that a proxy can decide which future
 
versions of the GNU General Public License can be used, that proxy's
 
public statement of acceptance of a version permanently authorizes you
 
to choose that version for the Program.
 

	
 
  Later license versions may give you additional or different
 
permissions.  However, no additional obligations are imposed on any
 
author or copyright holder as a result of your choosing to follow a
 
later version.
 

	
 
  15. Disclaimer of Warranty.
 

	
 
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 

	
 
  16. Limitation of Liability.
 

	
 
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 
SUCH DAMAGES.
 

	
 
  17. Interpretation of Sections 15 and 16.
 

	
 
  If the disclaimer of warranty and limitation of liability provided
 
above cannot be given local legal effect according to their terms,
 
reviewing courts shall apply local law that most closely approximates
 
an absolute waiver of all civil liability in connection with the
 
Program, unless a warranty or assumption of liability accompanies a
 
copy of the Program in return for a fee.
 

	
 
                     END OF TERMS AND CONDITIONS
 

	
 
            How to Apply These Terms to Your New Programs
 

	
 
  If you develop a new program, and you want it to be of the greatest
 
possible use to the public, the best way to achieve this is to make it
 
free software which everyone can redistribute and change under these terms.
 

	
 
  To do so, attach the following notices to the program.  It is safest
 
to attach them to the start of each source file to most effectively
 
state the exclusion of warranty; and each file should have at least
 
the "copyright" line and a pointer to where the full notice is found.
 

	
 
    <one line to give the program's name and a brief idea of what it does.>
 
    Copyright (C) <year>  <name of author>
 

	
 
    This program is free software: you can redistribute it and/or modify
 
    it under the terms of the GNU General Public License as published by
 
    the Free Software Foundation, either version 3 of the License, or
 
    (at your option) any later version.
 

	
 
    This program is distributed in the hope that it will be useful,
 
    but WITHOUT ANY WARRANTY; without even the implied warranty of
 
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 
    GNU General Public License for more details.
 

	
 
    You should have received a copy of the GNU General Public License
 
    along with this program.  If not, see <http://www.gnu.org/licenses/>.
 

	
 
Also add information on how to contact you by electronic and paper mail.
 

	
 
  If the program does terminal interaction, make it output a short
 
notice like this when it starts in an interactive mode:
 

	
 
    <program>  Copyright (C) <year>  <name of author>
 
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
 
    This is free software, and you are welcome to redistribute it
 
    under certain conditions; type `show c' for details.
 

	
 
The hypothetical commands `show w' and `show c' should show the appropriate
 
parts of the General Public License.  Of course, your program's commands
 
might be different; for a GUI interface, you would use an "about box".
 

	
 
  You should also get your employer (if you work as a programmer) or school,
 
if any, to sign a "copyright disclaimer" for the program, if necessary.
 
For more information on this, and how to apply and follow the GNU GPL, see
 
<http://www.gnu.org/licenses/>.
 

	
 
  The GNU General Public License does not permit incorporating your program
 
into proprietary programs.  If your program is a subroutine library, you
 
may consider it more useful to permit linking proprietary applications with
 
the library.  If this is what you want to do, use the GNU Lesser General
 
Public License instead of this License.  But first, please read
 
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

                GNU Free Documentation License
 
                 Version 1.3, 3 November 2008
 

	
 

	
 
 Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
 
     <http://fsf.org/>
 
 Everyone is permitted to copy and distribute verbatim copies
 
 of this license document, but changing it is not allowed.
 

	
 
0. PREAMBLE
 

	
 
The purpose of this License is to make a manual, textbook, or other
 
functional and useful document "free" in the sense of freedom: to
 
assure everyone the effective freedom to copy and redistribute it,
 
with or without modifying it, either commercially or noncommercially.
 
Secondarily, this License preserves for the author and publisher a way
 
to get credit for their work, while not being considered responsible
 
for modifications made by others.
 

	
 
This License is a kind of "copyleft", which means that derivative
 
works of the document must themselves be free in the same sense.  It
 
complements the GNU General Public License, which is a copyleft
 
license designed for free software.
 

	
 
We have designed this License in order to use it for manuals for free
 
software, because free software needs free documentation: a free
 
program should come with manuals providing the same freedoms that the
 
software does.  But this License is not limited to software manuals;
 
it can be used for any textual work, regardless of subject matter or
 
whether it is published as a printed book.  We recommend this License
 
principally for works whose purpose is instruction or reference.
 

	
 

	
 
1. APPLICABILITY AND DEFINITIONS
 

	
 
This License applies to any manual or other work, in any medium, that
 
contains a notice placed by the copyright holder saying it can be
 
distributed under the terms of this License.  Such a notice grants a
 
world-wide, royalty-free license, unlimited in duration, to use that
 
work under the conditions stated herein.  The "Document", below,
 
refers to any such manual or work.  Any member of the public is a
 
licensee, and is addressed as "you".  You accept the license if you
 
copy, modify or distribute the work in a way requiring permission
 
under copyright law.
 

	
 
A "Modified Version" of the Document means any work containing the
 
Document or a portion of it, either copied verbatim, or with
 
modifications and/or translated into another language.
 

	
 
A "Secondary Section" is a named appendix or a front-matter section of
 
the Document that deals exclusively with the relationship of the
 
publishers or authors of the Document to the Document's overall
 
subject (or to related matters) and contains nothing that could fall
 
directly within that overall subject.  (Thus, if the Document is in
 
part a textbook of mathematics, a Secondary Section may not explain
 
any mathematics.)  The relationship could be a matter of historical
 
connection with the subject or with related matters, or of legal,
 
commercial, philosophical, ethical or political position regarding
 
them.
 

	
 
The "Invariant Sections" are certain Secondary Sections whose titles
 
are designated, as being those of Invariant Sections, in the notice
 
that says that the Document is released under this License.  If a
 
section does not fit the above definition of Secondary then it is not
 
allowed to be designated as Invariant.  The Document may contain zero
 
Invariant Sections.  If the Document does not identify any Invariant
 
Sections then there are none.
 

	
 
The "Cover Texts" are certain short passages of text that are listed,
 
as Front-Cover Texts or Back-Cover Texts, in the notice that says that
 
the Document is released under this License.  A Front-Cover Text may
 
be at most 5 words, and a Back-Cover Text may be at most 25 words.
 

	
 
A "Transparent" copy of the Document means a machine-readable copy,
 
represented in a format whose specification is available to the
 
general public, that is suitable for revising the document
 
straightforwardly with generic text editors or (for images composed of
 
pixels) generic paint programs or (for drawings) some widely available
 
drawing editor, and that is suitable for input to text formatters or
 
for automatic translation to a variety of formats suitable for input
 
to text formatters.  A copy made in an otherwise Transparent file
 
format whose markup, or absence of markup, has been arranged to thwart
 
or discourage subsequent modification by readers is not Transparent.
 
An image format is not Transparent if used for any substantial amount
 
of text.  A copy that is not "Transparent" is called "Opaque".
 

	
 
Examples of suitable formats for Transparent copies include plain
 
ASCII without markup, Texinfo input format, LaTeX input format, SGML
 
or XML using a publicly available DTD, and standard-conforming simple
 
HTML, PostScript or PDF designed for human modification.  Examples of
 
transparent image formats include PNG, XCF and JPG.  Opaque formats
 
include proprietary formats that can be read and edited only by
 
proprietary word processors, SGML or XML for which the DTD and/or
 
processing tools are not generally available, and the
 
machine-generated HTML, PostScript or PDF produced by some word
 
processors for output purposes only.
 

	
 
The "Title Page" means, for a printed book, the title page itself,
 
plus such following pages as are needed to hold, legibly, the material
 
this License requires to appear in the title page.  For works in
 
formats which do not have any title page as such, "Title Page" means
 
the text near the most prominent appearance of the work's title,
 
preceding the beginning of the body of the text.
 

	
 
The "publisher" means any person or entity that distributes copies of
 
the Document to the public.
 

	
 
A section "Entitled XYZ" means a named subunit of the Document whose
 
title either is precisely XYZ or contains XYZ in parentheses following
 
text that translates XYZ in another language.  (Here XYZ stands for a
 
specific section name mentioned below, such as "Acknowledgements",
 
"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
 
of such a section when you modify the Document means that it remains a
 
section "Entitled XYZ" according to this definition.
 

	
 
The Document may include Warranty Disclaimers next to the notice which
 
states that this License applies to the Document.  These Warranty
 
Disclaimers are considered to be included by reference in this
 
License, but only as regards disclaiming warranties: any other
 
implication that these Warranty Disclaimers may have is void and has
 
no effect on the meaning of this License.
 

	
 
2. VERBATIM COPYING
 

	
 
You may copy and distribute the Document in any medium, either
 
commercially or noncommercially, provided that this License, the
 
copyright notices, and the license notice saying this License applies
 
to the Document are reproduced in all copies, and that you add no
 
other conditions whatsoever to those of this License.  You may not use
 
technical measures to obstruct or control the reading or further
 
copying of the copies you make or distribute.  However, you may accept
 
compensation in exchange for copies.  If you distribute a large enough
 
number of copies you must also follow the conditions in section 3.
 

	
 
You may also lend copies, under the same conditions stated above, and
 
you may publicly display copies.
 

	
 

	
 
3. COPYING IN QUANTITY
 

	
 
If you publish printed copies (or copies in media that commonly have
 
printed covers) of the Document, numbering more than 100, and the
 
Document's license notice requires Cover Texts, you must enclose the
 
copies in covers that carry, clearly and legibly, all these Cover
 
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
 
the back cover.  Both covers must also clearly and legibly identify
 
you as the publisher of these copies.  The front cover must present
 
the full title with all words of the title equally prominent and
 
visible.  You may add other material on the covers in addition.
 
Copying with changes limited to the covers, as long as they preserve
 
the title of the Document and satisfy these conditions, can be treated
 
as verbatim copying in other respects.
 

	
 
If the required texts for either cover are too voluminous to fit
 
legibly, you should put the first ones listed (as many as fit
 
reasonably) on the actual cover, and continue the rest onto adjacent
 
pages.
 

	
 
If you publish or distribute Opaque copies of the Document numbering
 
more than 100, you must either include a machine-readable Transparent
 
copy along with each Opaque copy, or state in or with each Opaque copy
 
a computer-network location from which the general network-using
 
public has access to download using public-standard network protocols
 
a complete Transparent copy of the Document, free of added material.
 
If you use the latter option, you must take reasonably prudent steps,
 
when you begin distribution of Opaque copies in quantity, to ensure
 
that this Transparent copy will remain thus accessible at the stated
 
location until at least one year after the last time you distribute an
 
Opaque copy (directly or through your agents or retailers) of that
 
edition to the public.
 

	
 
It is requested, but not required, that you contact the authors of the
 
Document well before redistributing any large number of copies, to
 
give them a chance to provide you with an updated version of the
 
Document.
 

	
 

	
 
4. MODIFICATIONS
 

	
 
You may copy and distribute a Modified Version of the Document under
 
the conditions of sections 2 and 3 above, provided that you release
 
the Modified Version under precisely this License, with the Modified
 
Version filling the role of the Document, thus licensing distribution
 
and modification of the Modified Version to whoever possesses a copy
 
of it.  In addition, you must do these things in the Modified Version:
 

	
 
A. Use in the Title Page (and on the covers, if any) a title distinct
 
   from that of the Document, and from those of previous versions
 
   (which should, if there were any, be listed in the History section
 
   of the Document).  You may use the same title as a previous version
 
   if the original publisher of that version gives permission.
 
B. List on the Title Page, as authors, one or more persons or entities
 
   responsible for authorship of the modifications in the Modified
 
   Version, together with at least five of the principal authors of the
 
   Document (all of its principal authors, if it has fewer than five),
 
   unless they release you from this requirement.
 
C. State on the Title page the name of the publisher of the
 
   Modified Version, as the publisher.
 
D. Preserve all the copyright notices of the Document.
 
E. Add an appropriate copyright notice for your modifications
 
   adjacent to the other copyright notices.
 
F. Include, immediately after the copyright notices, a license notice
 
   giving the public permission to use the Modified Version under the
 
   terms of this License, in the form shown in the Addendum below.
 
G. Preserve in that license notice the full lists of Invariant Sections
 
   and required Cover Texts given in the Document's license notice.
 
H. Include an unaltered copy of this License.
 
I. Preserve the section Entitled "History", Preserve its Title, and add
 
   to it an item stating at least the title, year, new authors, and
 
   publisher of the Modified Version as given on the Title Page.  If
 
   there is no section Entitled "History" in the Document, create one
 
   stating the title, year, authors, and publisher of the Document as
 
   given on its Title Page, then add an item describing the Modified
 
   Version as stated in the previous sentence.
 
J. Preserve the network location, if any, given in the Document for
 
   public access to a Transparent copy of the Document, and likewise
 
   the network locations given in the Document for previous versions
 
   it was based on.  These may be placed in the "History" section.
 
   You may omit a network location for a work that was published at
 
   least four years before the Document itself, or if the original
 
   publisher of the version it refers to gives permission.
 
K. For any section Entitled "Acknowledgements" or "Dedications",
 
   Preserve the Title of the section, and preserve in the section all
 
   the substance and tone of each of the contributor acknowledgements
 
   and/or dedications given therein.
 
L. Preserve all the Invariant Sections of the Document,
 
   unaltered in their text and in their titles.  Section numbers
 
   or the equivalent are not considered part of the section titles.
 
M. Delete any section Entitled "Endorsements".  Such a section
 
   may not be included in the Modified Version.
 
N. Do not retitle any existing section to be Entitled "Endorsements"
 
   or to conflict in title with any Invariant Section.
 
O. Preserve any Warranty Disclaimers.
 

	
 
If the Modified Version includes new front-matter sections or
 
appendices that qualify as Secondary Sections and contain no material
 
copied from the Document, you may at your option designate some or all
 
of these sections as invariant.  To do this, add their titles to the
 
list of Invariant Sections in the Modified Version's license notice.
 
These titles must be distinct from any other section titles.
 

	
 
You may add a section Entitled "Endorsements", provided it contains
 
nothing but endorsements of your Modified Version by various
 
parties--for example, statements of peer review or that the text has
 
been approved by an organization as the authoritative definition of a
 
standard.
 

	
 
You may add a passage of up to five words as a Front-Cover Text, and a
 
passage of up to 25 words as a Back-Cover Text, to the end of the list
 
of Cover Texts in the Modified Version.  Only one passage of
 
Front-Cover Text and one of Back-Cover Text may be added by (or
 
through arrangements made by) any one entity.  If the Document already
 
includes a cover text for the same cover, previously added by you or
 
by arrangement made by the same entity you are acting on behalf of,
 
you may not add another; but you may replace the old one, on explicit
 
permission from the previous publisher that added the old one.
 

	
 
The author(s) and publisher(s) of the Document do not by this License
 
give permission to use their names for publicity for or to assert or
 
imply endorsement of any Modified Version.
 

	
 

	
 
5. COMBINING DOCUMENTS
 

	
 
You may combine the Document with other documents released under this
 
License, under the terms defined in section 4 above for modified
 
versions, provided that you include in the combination all of the
 
Invariant Sections of all of the original documents, unmodified, and
 
list them all as Invariant Sections of your combined work in its
 
license notice, and that you preserve all their Warranty Disclaimers.
 

	
 
The combined work need only contain one copy of this License, and
 
multiple identical Invariant Sections may be replaced with a single
 
copy.  If there are multiple Invariant Sections with the same name but
 
different contents, make the title of each such section unique by
 
adding at the end of it, in parentheses, the name of the original
 
author or publisher of that section if known, or else a unique number.
 
Make the same adjustment to the section titles in the list of
 
Invariant Sections in the license notice of the combined work.
 

	
 
In the combination, you must combine any sections Entitled "History"
 
in the various original documents, forming one section Entitled
 
"History"; likewise combine any sections Entitled "Acknowledgements",
 
and any sections Entitled "Dedications".  You must delete all sections
 
Entitled "Endorsements".
 

	
 

	
 
6. COLLECTIONS OF DOCUMENTS
 

	
 
You may make a collection consisting of the Document and other
 
documents released under this License, and replace the individual
 
copies of this License in the various documents with a single copy
 
that is included in the collection, provided that you follow the rules
 
of this License for verbatim copying of each of the documents in all
 
other respects.
 

	
 
You may extract a single document from such a collection, and
 
distribute it individually under this License, provided you insert a
 
copy of this License into the extracted document, and follow this
 
License in all other respects regarding verbatim copying of that
 
document.
 

	
 

	
 
7. AGGREGATION WITH INDEPENDENT WORKS
 

	
 
A compilation of the Document or its derivatives with other separate
 
and independent documents or works, in or on a volume of a storage or
 
distribution medium, is called an "aggregate" if the copyright
 
resulting from the compilation is not used to limit the legal rights
 
of the compilation's users beyond what the individual works permit.
 
When the Document is included in an aggregate, this License does not
 
apply to the other works in the aggregate which are not themselves
 
derivative works of the Document.
 

	
 
If the Cover Text requirement of section 3 is applicable to these
 
copies of the Document, then if the Document is less than one half of
 
the entire aggregate, the Document's Cover Texts may be placed on
 
covers that bracket the Document within the aggregate, or the
 
electronic equivalent of covers if the Document is in electronic form.
 
Otherwise they must appear on printed covers that bracket the whole
 
aggregate.
 

	
 

	
 
8. TRANSLATION
 

	
 
Translation is considered a kind of modification, so you may
 
distribute translations of the Document under the terms of section 4.
 
Replacing Invariant Sections with translations requires special
 
permission from their copyright holders, but you may include
 
translations of some or all Invariant Sections in addition to the
 
original versions of these Invariant Sections.  You may include a
 
translation of this License, and all the license notices in the
 
Document, and any Warranty Disclaimers, provided that you also include
 
the original English version of this License and the original versions
 
of those notices and disclaimers.  In case of a disagreement between
 
the translation and the original version of this License or a notice
 
or disclaimer, the original version will prevail.
 

	
 
If a section in the Document is Entitled "Acknowledgements",
 
"Dedications", or "History", the requirement (section 4) to Preserve
 
its Title (section 1) will typically require changing the actual
 
title.
 

	
 

	
 
9. TERMINATION
 

	
 
You may not copy, modify, sublicense, or distribute the Document
 
except as expressly provided under this License.  Any attempt
 
otherwise to copy, modify, sublicense, or distribute it is void, and
 
will automatically terminate your rights under this License.
 

	
 
However, if you cease all violation of this License, then your license
 
from a particular copyright holder is reinstated (a) provisionally,
 
unless and until the copyright holder explicitly and finally
 
terminates your license, and (b) permanently, if the copyright holder
 
fails to notify you of the violation by some reasonable means prior to
 
60 days after the cessation.
 

	
 
Moreover, your license from a particular copyright holder is
 
reinstated permanently if the copyright holder notifies you of the
 
violation by some reasonable means, this is the first time you have
 
received notice of violation of this License (for any work) from that
 
copyright holder, and you cure the violation prior to 30 days after
 
your receipt of the notice.
 

	
 
Termination of your rights under this section does not terminate the
 
licenses of parties who have received copies or rights from you under
 
this License.  If your rights have been terminated and not permanently
 
reinstated, receipt of a copy of some or all of the same material does
 
not give you any rights to use it.
 

	
 

	
 
10. FUTURE REVISIONS OF THIS LICENSE
 

	
 
The Free Software Foundation may publish new, revised versions of the
 
GNU Free Documentation License from time to time.  Such new versions
 
will be similar in spirit to the present version, but may differ in
 
detail to address new problems or concerns.  See
 
http://www.gnu.org/copyleft/.
 

	
 
Each version of the License is given a distinguishing version number.
 
If the Document specifies that a particular numbered version of this
 
License "or any later version" applies to it, you have the option of
 
following the terms and conditions either of that specified version or
 
of any later version that has been published (not as a draft) by the
 
Free Software Foundation.  If the Document does not specify a version
 
number of this License, you may choose any version ever published (not
 
as a draft) by the Free Software Foundation.  If the Document
 
specifies that a proxy can decide which future versions of this
 
License can be used, that proxy's public statement of acceptance of a
 
version permanently authorizes you to choose that version for the
 
Document.
 

	
 
11. RELICENSING
 

	
 
"Massive Multiauthor Collaboration Site" (or "MMC Site") means any
 
World Wide Web server that publishes copyrightable works and also
 
provides prominent facilities for anybody to edit those works.  A
 
public wiki that anybody can edit is an example of such a server.  A
 
"Massive Multiauthor Collaboration" (or "MMC") contained in the site
 
means any set of copyrightable works thus published on the MMC site.
 

	
 
"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 
 
license published by Creative Commons Corporation, a not-for-profit 
 
corporation with a principal place of business in San Francisco, 
 
California, as well as future copyleft versions of that license 
 
published by that same organization.
 

	
 
"Incorporate" means to publish or republish a Document, in whole or in 
 
part, as part of another Document.
 

	
 
An MMC is "eligible for relicensing" if it is licensed under this 
 
License, and if all works that were first published under this License 
 
somewhere other than this MMC, and subsequently incorporated in whole or 
 
in part into the MMC, (1) had no cover texts or invariant sections, and 
 
(2) were thus incorporated prior to November 1, 2008.
 

	
 
The operator of an MMC Site may republish an MMC contained in the site
 
under CC-BY-SA on the same site at any time before August 1, 2009,
 
provided the MMC is eligible for relicensing.
 

	
 

	
 
ADDENDUM: How to use this License for your documents
 

	
 
To use this License in a document you have written, include a copy of
 
the License in the document and put the following copyright and
 
license notices just after the title page:
 

	
 
    Copyright (c)  YEAR  YOUR NAME.
 
    Permission is granted to copy, distribute and/or modify this document
 
    under the terms of the GNU Free Documentation License, Version 1.3
 
    or any later version published by the Free Software Foundation;
 
    with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
 
    A copy of the license is included in the section entitled "GNU
 
    Free Documentation License".
 

	
 
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
 
replace the "with...Texts." line with this:
 

	
 
    with the Invariant Sections being LIST THEIR TITLES, with the
 
    Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
 

	
 
If you have Invariant Sections without Cover Texts, or some other
 
combination of the three, merge those two alternatives to suit the
 
situation.
 

	
 
If your document contains nontrivial examples of program code, we
 
recommend releasing these examples in parallel under your choice of
 
free software license, such as the GNU General Public License,
 
to permit their use in free software.

:rem:`|||:sec:|||`\ Installation
 
==================================================
 

	
 
#. Alias `/vacation` in `lib/ws-vacation.conf.in` ändern, falls
 
   gewünscht.
 

	
 
#. Folgende Kommandos ausführen, um die fertigen Dateien zu erzeugen:
 

	
 
   >>> make clean
 
   >>> make
 

	
 
   Damit wird das Installationverzeichnis an den notwendigen Stellen
 
   eingetragen.
 

	
 
#. Datei `lib/ws-vacation.conf` nach `/etc/apache2/conf.d/` kopieren.
 

	
 
#. Apache server neu laden:
 

	
 
   >>> rcapache2 reload.
 

	
 
#. Damit der WWW-Prozess das vacation(1)-Kommando als beliebiger
 
   Benutzer (außer `root`) ausführen kann, muss die Datei
 
   `lib/ws-vacation-sudo` in das Verzeichnis `/etc/sudoers.d` kopiert
 
   werden (ubuntu):
 

	
 
   >>> cp lib/ws-vacation-sudo /etc/sudoers.d/ws-vacation-sudo
 
   >>> chmod 0440 /etc/sudoers.d/ws-vacation-sudo
 

	
 
   oder an die Datei `/etc/sudoers` angehängt werden (SuSE):
 

	
 
   >>> cat lib/ws-vacation-sudo >>/etc/sudoers
 

	
 
==================================================
 
:rem:`|||:sec:|||`\ Benutzerverwaltung
 
==================================================

#   The  snippet category is  determined as  the substring  before the
 
#   first underscore.
 
#
 
#   If no mode is specified for a snippet, the prefix category is used
 
#   as such.
 
#
 
#   If a supplied  snippet name for storage does  not have a category,
 
#   the current mode is automatically prepended.
 
#
 
#   In order to allow for  an optional sub-category / name scheme, the
 
#   first dot  is used separate  categories and name. This  allows for
 
#   underscores  to appear  in  a  name part  after  the dot,  without
 
#   implying a category::
 
#
 
#       <category> `_` [ <sub-category> `.` ] <name>
 
#
 
#   The sub-category is  just a suggestion and has  no special meaning
 
#   for snippets(1).
 
#
 
#   The dot-separator is only used  to determine the end of substring,
 
#   where snippets(1) looks for an underscore. It is entirely optional
 
#   and has no other special meaning.

# @s@SNIPPET TAG QUOTING@e@
 
#   Snippet  tags are  only recognized  at  the beginning  of a  line,
 
#   optionally proceeded  by a comment start  skip. Therefore, snippet
 
#   tags within  a line do not  need to be quoted.  Other snippet tags
 
#   can be quoted through the final replacement mechanism. E.g.::
 
#
 
#     ;; |@|fempty@|<-snap->||
 
#
 
#   results in::
 
#
 
#     ;; ||<-snap->||
 
#
 
#   and still allows symbol  tag navigation with the reduced delimiter
 
#   set `("|<-" . "->|")`.
 

	
 
# @s@REPLACEMENT QUOTING@eb@

#     @|||quoted@  => @||quoted@
 
#     @||||quoted@ => @|||quoted@

# @s@INCLUDE FILE RX REPLACEMENTS@e@
 
#   The  first  level  of  quotes   is  removed  on  FILE-RX  and  the
 
#   appropriate replacements  are filled  in.  Then, another  level of
 
#   quotes is removed. This works exactly like the `subst` command.
 
#
 
#   If you  wish to match a  filename with a valid  replacement in it,
 
#   you must  double-quote it (e.g.  `@|||space@`), or  use other means
 
#   like @\|match@ or `@[m]atch@`.
 
#
 
#   The following replacements are  defined as defaults (i.e., if they
 
#   are not  yet defined) when replacing  the first quote  level of an
 
#   `include` file regexp::
 
#
 
#     @|snip_fn_space@  => ` `
 
#     @|snip_fn_tab@    => `\t`
 
#     @|snip_fn_cr@     => `\r`
 
#     @|snip_fn_nl@     => `\n`
 

	
 
# @s@CONFIGURATION@e@
 
#   SNIPS_PATH is taken from the environment variable `SNIPS_PATH`. If
 
#   the variable is not set, `${HOME}/snippets` is used.
 
#
 
#   SNIPS_DIR   is   then   taken   from  the   environment   variable
 
#   `SNIPS_DIR`.  If the  variable is  not set,  the first  element of
 
#   SNIPS_PATH is used.
 
#
 
#   All  directories  named  `.snippets`  going up  from  the  current
 
#   directory to the root level are prepended to SNIPS_PATH in reverse
 
#   order.  I.e., the  `.snippets`  directory in  the current  working
 
#   directory takes highest precedence.
 
#
 
#   SNIPS_PATH  is  searched for  `snip_setup`.   The first  occurence
 
#   found is processed. Any resulting text is discarded.
 
#
 
#   SNIPS_PATH is then  searched in reverse order for  all files named
 
#   `.snips.rc`,  which  are  all  processed. Any  resulting  text  is
 
#   discarded.
 
#
 
#   It  is really  intended  to process  `snip_setup` and  `.snips.rc`
 
#   before option processing. However, this still remains ``|:todo:|``.
 
#
 
#   The   configuration  processing   is  mainly   useful   to  define
 
#   replacements. But  can also be  used with the `exec`  mechanism to
 
#   create directories, files and the like.
 

	
 
# @s@ENVIRONMENT@eb@
 
#   SNIPS_PATH is searched for snippets
 
#      SNIPS_PATH="${SNIPS_PATH-${HOME}/snippets}"
 
#
 
#   SNIPS_DIR is used to store snippets
 
#     SNIPS_DIR="${SNIPS_DIR-first element of SNIPS_PATH}"
 
#
 
#   SNIPS_MODE is the default mode to be used.

=head1 DESCRIPTION
 

	
 
UUID::Tiny is a lightweight, low dependency Pure Perl module for UUID
 
creation and testing. This module provides the creation of version 1 time
 
based UUIDs (using random multicast MAC addresses), version 3 MD5 based UUIDs,
 
version 4 random UUIDs, and version 5 SHA-1 based UUIDs.
 

	
 
ATTENTION! UUID::Tiny uses Perl's C<rand()> to create the basic random
 
numbers, so the created v4 UUIDs are B<not> cryptographically strong!
 

	
 
No fancy OO interface, no plethora of different UUID representation formats
 
and transformations - just string and binary. Conversion, test and time
 
functions equally accept UUIDs and UUID strings, so don't bother to convert
 
UUIDs for them!
 

	
 
All constants and public functions are exported by default, because if you
 
didn't need/want them, you wouldn't use this module ...
 

	
 
UUID::Tiny deliberately uses a minimal functional interface for UUID creation
 
(and conversion/testing), because in this case OO looks like overkill to me
 
and makes the creation and use of UUIDs unnecessarily complicated.
 

	
 
If you need raw performance for UUID creation, or the real MAC address in
 
version 1 UUIDs, or an OO interface, and if you can afford module compilation
 
and installation on the target system, then better look at other CPAN UUID
 
modules like L<Data::UUID>.
 

	
 
This module is "fork safe", especially for random UUIDs (it works around
 
Perl's rand() problem when forking processes).
 

	
 
This module should be "thread safe," because its global variables
 
are locked in the functions that access them. (Not tested - if you can provide
 
some tests, please tell me!)

=head1 DEPENDENCIES
 

	
 
This module should run from Perl 5.8 up and uses mostly standard (5.8 core)
 
modules for its job. No compilation or installation required. These are the
 
modules UUID::Tiny depends on:
 

	
 
    Carp
 
    Digest::MD5   Perl 5.8 core
 
    Digest::SHA   Perl 5.10 core (or Digest::SHA1, or Digest::SHA::PurePerl)
 
    MIME::Base64  Perl 5.8 core
 
    Time::HiRes   Perl 5.8 core
 
    POSIX         Perl 5.8 core
 

	
 
If you are using this module on a Perl prior to 5.10 and you don't have
 
Digest::SHA1 installed, you can use Digest::SHA::PurePerl instead.

=head1 ATTENTION! NEW STANDARD INTERFACE (IN PREPARATION FOR V2.00)
 

	
 
After some debate I'm convinced that it is more Perlish (and far easier to
 
write) to use all-lowercase function names - without exceptions. And that it
 
is more polite to export symbols only on demand.
 

	
 
While the 1.0x versions will continue to export the old, "legacy" interface on
 
default, the future standard interface is available using the C<:std> tag on
 
import from version 1.02 on:
 

	
 
    use UUID::Tiny ':std';
 
    my $md5_uuid = create_uuid(UUID_MD5, $str);
 

	
 
In preparation for the upcoming version 2.00 of UUID::Tiny you should use the
 
C<:legacy> tag if you want to stay with the version 1.0x interface:
 

	
 
    use UUID::Tiny ':legacy';
 
    my $md5_uuid = create_UUID(UUID_V3, $str);

This module provides the common pre-defined namespace UUIDs (shown with their
 
string representation):
 

	
 
    UUID_NS_DNS:  '6ba7b810-9dad-11d1-80b4-00c04fd430c8'

=item B<UUID versions>
 

	
 
This module provides the UUID version numbers as constants:
 

	
 
    UUID_V1
 
    UUID_V3
 
    UUID_V4
 
    UUID_V5
 

	
 
With C<use UUID::Tiny ':std';> you get additional, "speaking" constants:
 

	
 
    UUID_TIME
 
    UUID_MD5
 
    UUID_RANDOM
 
    UUID_SHA1

=item B<UUID_SHA1_AVAIL>
 

	
 
    my $uuid = create_UUID( UUID_SHA1_AVAIL? UUID_V5 : UUID_V3, $str );
 

	
 
This function returns 1 if a module to create SHA-1 digests could be loaded, 0
 
otherwise.
 

	
 
UUID::Tiny (since version 1.02) tries to load Digest::SHA, Digest::SHA1 or
 
Digest::SHA::PurePerl, but does not die if none of them is found. Instead
 
C<create_UUID()> and C<create_UUID_as_string()> die when trying to create an
 
SHA-1 based UUID without an appropriate module available.

=head1 FUNCTIONS
 

	
 
All public functions are exported by default (they should not collide with
 
other functions).
 

	
 
C<create_UUID()> creates standard binary UUIDs in network byte order
 
(MSB first), C<create_UUID_as_string()> creates the standard string
 
represantion of UUIDs.
 

	
 
All query and test functions (except C<is_UUID_string>) accept both
 
representations.

=item B<create_UUID()>, B<create_uuid()> (:std)
 

	
 
    my $v1_mc_UUID   = create_UUID();
 
    my $v1_mc_UUID   = create_UUID(UUID_V1);
 
    my $v3_md5_UUID  = create_UUID(UUID_V3, $ns_uuid, $name_or_filehandle);
 
    my $v3_md5_UUID  = create_UUID(UUID_V3, $name_or_filehandle);
 
    my $v4_rand_UUID = create_UUID(UUID_V4);
 
    my $v5_sha1_UUID = create_UUID(UUID_V5, $ns_uuid, $name_or_filehandle);
 
    my $v5_sha1_UUID = create_UUID(UUID_V5, $name_or_filehandle);
 

	
 
Creates a binary UUID in network byte order (MSB first). For v3 and v5 UUIDs a
 
C<SCALAR> (normally a string), C<GLOB> ("classic" file handle) or C<IO> object
 
(i.e. C<IO::File>) can be used; files have to be opened for reading.
 

	
 
I found no hint if and how UUIDs should be created from file content. It seems
 
to be undefined, but it is useful - so I would suggest to use UUID_NIL as the
 
namespace UUID, because no "real name" is used; UUID_NIL is used by default if
 
a namespace UUID is missing (only 2 arguments are used).

In addition to the standard UUID string representation and its URN forms
 
(starting with C<urn:uuid:> or C<uuid:>), this function accepts 32 digit hex
 
strings, variants with different positions of C<-> and Base64 encoded UUIDs.
 

	
 
Throws an exception if string can't be interpreted as a UUID.
 

	
 
If you want to make shure to have a "pure" standard UUID representation, check
 
with C<is_UUID_string>!

=item B<Why version 1 only with random multi-cast MAC addresses?>
 

	
 
The random multi-cast MAC address gives privacy, and getting the real MAC
 
address with Perl is really dirty (and slow);
 

	
 
=item B<Should version 3 or version 5 be used?>
 

	
 
Using SHA-1 reduces the probabillity of collisions and provides a better
 
"randomness" of the resulting UUID compared to MD5. Version 5 is recommended
 
in RFC 4122 if backward compatibility is not an issue.
 

	
 
Using MD5 (version 3) has a better performance. This could be important with
 
creating UUIDs from file content rather than names.

See RFC 4122 (L<http://www.ietf.org/rfc/rfc4122.txt>) for technical details on
 
UUIDs.

Some of this code is based on UUID::Generator by ITO Nobuaki
 
E<lt>banb@cpan.orgE<gt>. But that module is announced to be marked as
 
"deprecated" in the future and it is much too complicated for my liking.
 

	
 
So I decided to reduce it to the necessary parts and to re-implement those
 
parts with a functional interface ...
 

	
 
Jesse Vincent, C<< <jesse at bestpractical.com> >>, improved version 1.02 with
 
his tips and a heavy refactoring.

Kudos to ITO Nobuaki E<lt>banb@cpan.orgE<gt> for his UUID::Generator::PurePerl
 
module! My work is based on his code, and without it I would've been lost with
 
all those incomprehensible RFC texts and C codes ...
 

	
 
Thanks to Jesse Vincent (C<< <jesse at bestpractical.com> >>) for his feedback, tips and refactoring!
