cortav  Check-in [f552ca3518]

there's currently no standard way to describe the intent and desired formatting of a document besides placing pragmata in the source file itself. this is extremely suboptimal, as when generating collections of documents, it's ideal to be able to keep all formatting information in one place. users should also be able to specify their own styling overrides that describe the way they prefer to read [`cortav] files, especially for uses like gemini or gopher integration.

at some point soon [`cortav] needs to address this by adding intent files that can be activated from outside the source file, such as with a command line flag or a configuration file setting. these will probably consist of lines that are interpreted as pragmata. in addition to the standard intent format however, individual implementations should feel free to provide their own ways to provide intent metadata; e.g. the reference implementation, which has a lua interpreter available, should be able to take a lua script that runs after the parse stage and makes arbitrary alterations to the AST. this will be particularly useful for the end-user who wishes to specify a particular format she likes reading her files in without forcing that format on everyone she sends the compiled document to, as it will be able to interrogate the document and make intelligent decisions about what pragmata to apply.

intent files should also be able to define [>rsrc resources], [>ctxvar context variables], and macros.

                    GNU AFFERO GENERAL PUBLIC LICENSE
                       Version 3, 19 November 2007

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

                            Preamble

  The GNU Affero General Public License is a free, copyleft license for
software and other kinds of works, specifically designed to ensure
cooperation with the community in the case of network server software.

  The licenses for most software and other practical works are designed
to take away your freedom to share and change the works.  By contrast,
our General Public Licenses are 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.

  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.

  Developers that use our General Public Licenses protect your rights
with two steps: (1) assert copyright on the software, and (2) offer
you this License which gives you legal permission to copy, distribute
and/or modify the software.

  A secondary benefit of defending all users' freedom is that
improvements made in alternate versions of the program, if they
receive widespread use, become available for other developers to
incorporate.  Many developers of free software are heartened and
encouraged by the resulting cooperation.  However, in the case of
software used on network servers, this result may fail to come about.
The GNU General Public License permits making a modified version and
letting the public access it on a server without ever releasing its
source code to the public.

  The GNU Affero General Public License is designed specifically to
ensure that, in such cases, the modified source code becomes available
to the community.  It requires the operator of a network server to
provide the source code of the modified version running there to the
users of that server.  Therefore, public use of a modified version, on
a publicly accessible server, gives the public access to the source
code of the modified version.

  An older license, called the Affero General Public License and
published by Affero, was designed to accomplish similar goals.  This is
a different license, not a version of the Affero GPL, but Affero has
released a new version of the Affero GPL which permits relicensing under
this license.

  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 Affero 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. Remote Network Interaction; Use with the GNU General Public License.

  Notwithstanding any other provision of this License, if you modify the
Program, your modified version must prominently offer all users
interacting with it remotely through a computer network (if your version
supports such interaction) an opportunity to receive the Corresponding
Source of your version by providing access to the Corresponding Source
from a network server at no charge, through some standard or customary
means of facilitating copying of software.  This Corresponding Source
shall include the Corresponding Source for any work covered by version 3
of the GNU General Public License that is incorporated pursuant to the
following paragraph.

  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 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 work with which it is combined will remain governed by version
3 of the GNU General Public License.

  14. Revised Versions of this License.

  The Free Software Foundation may publish revised and/or new versions of
the GNU Affero 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 Affero 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 Affero 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 Affero 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 Affero 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 Affero General Public License for more details.

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

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

  If your software can interact with users remotely through a computer
network, you should also make sure that it provides a way for users to
get its source.  For example, if your program is a web application, its
interface could display a "Source" link that leads users to an archive
of the code.  There are many ways you could offer source, and different
solutions will be better for different programs; see section 13 for the
specific requirements.

  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 AGPL, see

OPEN-SOURCE-LIZENZ FÜR DIE EUROPÄISCHE UNION v. 1.2 
EUPL © Europäische Union 2007, 2016 
Diese Open-Source-Lizenz für die Europäische Union („EUPL“) gilt für Werke (im Sinne der nachfolgenden Begriffsbestimmung), die unter EUPL-Bedingungen zur Verfügung gestellt werden. Das Werk darf nur in der durch diese Lizenz gestatteten Form genutzt werden (insoweit eine solche Nutzung dem Urheber vorbehalten ist). 
Das Werk wird unter den Bedingungen dieser Lizenz zur Verfügung gestellt, wenn der Lizenzgeber (im Sinne der nachfolgenden Begriffsbestimmung) den folgenden Hinweis unmittelbar hinter dem Urheberrechtshinweis dieses Werks anbringt: 
                      Lizenziert unter der EUPL 
oder in einer anderen Form zum Ausdruck bringt, dass er es unter der EUPL lizenzieren möchte. 

1.Begriffsbestimmungen 
Für diese Lizenz gelten folgende Begriffsbestimmungen:  
— „Lizenz“:diese Lizenz.

— „Bearbeitungen“:die Werke oder Software, die der Lizenznehmer auf der Grundlage des Originalwerks oder seiner Bearbeitungen schaffen kann. In dieser Lizenz wird nicht festgelegt, wie umfangreich die Änderung oder wie stark die Abhängigkeit vom Originalwerk für eine Einstufung als Bearbeitung sein muss; dies bestimmt sich nach dem Urheberrecht, das in dem unter Artikel 15 aufgeführten Land anwendbar ist.  
— „Werk“:das Originalwerk oder seine Bearbeitungen.  
— „Quellcode“:diejenige Form des Werkes, die zur Auffassung durch den Menschen bestimmt ist und die am besten geeignet ist, um vom Menschen verstanden und verändert zu werden.  
— „Ausführbarer Code“:die — üblicherweise — kompilierte Form des Werks, die von einem Computer als Programm ausgeführt werden soll.  
— „Lizenzgeber“:die natürliche oder juristische Person, die das Werk unter der Lizenz verbreitet oder zugänglich macht.  
— „Bearbeiter“:jede natürliche oder juristische Person, die das Werk unter der Lizenz verändert oder auf andere Weise zur Schaffung einer Bearbeitung beiträgt.

2.Umfang der Lizenzrechte 
Der Lizenzgeber erteilt Ihnen hiermit für die Gültigkeitsdauer der am Originalwerk bestehenden Urheberrechte eine weltweite, unentgeltliche, nicht ausschließliche, unterlizenzierbare Lizenz, die Sie berechtigt: 
—  das Werk uneingeschränkt zu nutzen, 
—  das Werk zu vervielfältigen, 
—  das Werk zu verändern und Bearbeitungen auf der Grundlage des Werks zu schaffen, 
—  das Werk öffentlich zugänglich zu machen, was das Recht einschließt, das Werk oder Vervielfältigungsstücke davon öffentlich bereitzustellen oder wahrnehmbar zu machen oder das Werk, soweit möglich, öffentlich aufzuführen, 
—  das Werk oder Vervielfältigungen davon zu verbreiten, 
—  das Werk oder Vervielfältigungen davon zu vermieten oder zu verleihen, 
—  das Werk oder Vervielfältigungen davon weiter zu lizenzieren. 
Für die Wahrnehmung dieser Rechte können beliebige, derzeit bekannte oder künftige Medien, Träger und Formate verwendet werden, soweit das geltende Recht dem nicht entgegensteht. Für die Länder, in denen Urheberpersönlichkeitsrechte an dem Werk bestehen, verzichtet der Lizenzgeber im gesetzlich zulässigen Umfang auf seine Urheberpersönlichkeitsrechte, um die Lizenzierung der oben aufgeführten Verwertungsrechte wirksam durchführen zu können. Der Lizenzgeber erteilt dem Lizenznehmer ein nicht ausschließliches, unentgeltliches Nutzungsrecht an seinen Patenten, sofern dies zur Ausübung der durch die Lizenz erteilten Nutzungsrechte am Werk notwendig ist. 

3.Zugänglichmachung des Quellcodes 
Der Lizenzgeber kann das Werk entweder als Quellcode oder als ausführbaren Code zur Verfügung stellen. Stellt er es als ausführbaren Code zur Verfügung, so stellt er darüber hinaus eine maschinenlesbare Kopie des Quellcodes für jedes von ihm verbreitete Vervielfältigungsstück des Werks zur Verfügung, oder er verweist in einem Vermerk im Anschluss an den dem Werk beigefügten Urheberrechtshinweis auf einen Speicherort, an dem problemlos und unentgeltlich auf den Quellcode zugegriffen werden kann, solange der Lizenzgeber das Werk verbreitet oder zugänglich macht. 

4.Einschränkungen des Urheberrechts
Es ist nicht Zweck dieser Lizenz, Ausnahmen oder Schranken der ausschließlichen Rechte des Urhebers am Werk, die dem Lizenznehmer zugutekommen, einzuschränken. Auch die Erschöpfung dieser Rechte bleibt von dieser Lizenz unberührt. 

5.Pflichten des Lizenznehmers 
Die Einräumung der oben genannten Rechte ist an mehrere Beschränkungen und Pflichten für den Lizenznehmer gebunden: 

Urheberrechtshinweis, Lizenztext, Nennung des Bearbeiters: Der Lizenznehmer muss alle Urheberrechts-, Patent- oder Markenrechtshinweise und alle Hinweise auf die Lizenz und den Haftungsausschluss unverändert lassen. Jedem von ihm verbreiteten oder zugänglich gemachten Vervielfältigungsstück des Werks muss der Lizenznehmer diese Hinweise sowie diese Lizenz beifügen. Der Lizenznehmer muss auf jedem abgeleiteten Werk deutlich darauf hinweisen, dass das Werk geändert wurde, und das Datum der Bearbeitung angeben.

„Copyleft“-Klausel: Der Lizenznehmer darf Vervielfältigungen des Originalwerks oder Bearbeitungen nur unter den Bedingungen dieser EUPL oder einer neueren Version dieser Lizenz verbreiten oder zugänglich machen, außer wenn das Originalwerk ausdrücklich nur unter dieser Lizenzversion — z. B. mit der Angabe „Nur EUPL V. 1.2“ — verbreitet werden darf. Der Lizenznehmer (der zum Lizenzgeber wird) darf für das Werk oder die Bearbeitung keine zusätzlichen Bedingungen anbieten oder vorschreiben, die die Bedingungen dieser Lizenz verändern oder einschränken. 

Kompatibilitäts-Klausel: Wenn der Lizenznehmer Bearbeitungen, die auf dem Werk und einem anderen Werk, das unter einer kompatiblen Lizenz lizenziert wurde, basieren, oder die Kopien dieser Bearbeitungen verbreitet oder zugänglich macht, kann dies unter den Bedingungen dieser kompatiblen Lizenz erfolgen. Unter „kompatibler Lizenz“ ist eine im Anhang dieser Lizenz angeführte Lizenz zu verstehen. Sollten die Verpflichtungen des Lizenznehmers aus der kompatiblen Lizenz mit denjenigen aus der vorliegenden Lizenz (EUPL) in Konflikt stehen, werden die Verpflichtungen aus der kompatiblen Lizenz Vorrang haben.

Bereitstellung des Quellcodes: Wenn der Lizenznehmer Vervielfältigungsstücke des Werks verbreitet oder zugänglich macht, muss er eine maschinenlesbare Fassung des Quellcodes mitliefern oder einen Speicherort angeben, über den problemlos und unentgeltlich so lange auf diesen Quellcode zugegriffen werden kann, wie der Lizenznehmer das Werk verbreitet oder zugänglich macht. 

Rechtsschutz: Diese Lizenz erlaubt nicht die Benutzung von Kennzeichen, Marken oder geschützten Namensrechten des Lizenzgebers, soweit dies nicht für die angemessene und übliche Beschreibung der Herkunft des Werks und der inhaltlichen Wiedergabe des Urheberrechtshinweises erforderlich ist.

6.Urheber und Bearbeiter 
Der ursprüngliche Lizenzgeber gewährleistet, dass er das Urheberrecht am Originalwerk innehat oder dieses an ihn lizenziert wurde und dass er befugt ist, diese Lizenz zu erteilen. 
Jeder Bearbeiter gewährleistet, dass er das Urheberrecht an den von ihm vorgenommenen Änderungen des Werks besitzt und befugt ist, diese Lizenz zu erteilen. 
Jedes Mal, wenn Sie die Lizenz annehmen, erteilen Ihnen der ursprüngliche Lizenzgeber und alle folgenden Bearbeiter eine Befugnis zur Nutzung ihrer Beiträge zum Werk unter den Bedingungen dieser Lizenz. 

7.Gewährleistungsausschluss 
Die Arbeit an diesem Werk wird laufend fortgeführt; es wird durch unzählige Bearbeiter ständig verbessert. Das Werk ist nicht vollendet und kann daher Fehler („bugs“) enthalten, die dieser Art der Entwicklung inhärent sind. 
Aus den genannten Gründen wird das Werk unter dieser Lizenz „so, wie es ist“ ohne jegliche Gewährleistung zur Verfügung gestellt. Dies gilt unter anderem — aber nicht ausschließlich — für Marktreife, Verwendbarkeit für einen bestimmten Zweck, Mängelfreiheit, Richtigkeit sowie Nichtverletzung von anderen Immaterialgüterrechten als dem Urheberrecht (vgl. dazu Artikel 6 dieser Lizenz). 
Dieser Gewährleistungsausschluss ist wesentlicher Bestandteil der Lizenz und Bedingung für die Einräumung von Rechten an dem Werk.

8.Haftungsausschluss/Haftungsbeschränkung 
Außer in Fällen von Vorsatz oder der Verursachung von Personenschäden haftet der Lizenzgeber nicht für direkte oder indirekte, materielle oder immaterielle Schäden irgendwelcher Art, die aus der Lizenz oder der Benutzung des Werks folgen; dies gilt unter anderem, aber nicht ausschließlich, für Firmenwertverluste, Produktionsausfall, Computerausfall oder Computerfehler, Datenverlust oder wirtschaftliche Schäden, und zwar auch dann, wenn der Lizenzgeber auf die Möglichkeit solcher Schäden hingewiesen wurde. Unabhängig davon haftet der Lizenzgeber im Rahmen der gesetzlichen Produkthaftung, soweit die entsprechenden Regelungen auf das Werk anwendbar sind. 

9.Zusatzvereinbarungen 
Wenn Sie das Werk verbreiten, können Sie Zusatzvereinbarungen schließen, in denen Verpflichtungen oder Dienstleistungen festgelegt werden, die mit dieser Lizenz vereinbar sind. Sie dürfen Verpflichtungen indessen nur in Ihrem eigenen Namen und auf Ihre eigene Verantwortung eingehen, nicht jedoch im Namen des ursprünglichen Lizenzgebers oder eines anderen Bearbeiters, und nur, wenn Sie sich gegenüber allen Bearbeitern verpflichten, sie zu entschädigen, zu verteidigen und von der Haftung freizustellen, falls aufgrund der von Ihnen eingegangenen Gewährleistungsverpflichtung oder Haftungsübernahme Forderungen gegen sie geltend gemacht werden oder eine Haftungsverpflichtung entsteht. 

10.Annahme der Lizenz 
Sie können den Bestimmungen dieser Lizenz zustimmen, indem Sie das Symbol „Lizenz annehmen“ unter dem Fenster mit dem Lizenztext anklicken oder indem Sie Ihre Zustimmung auf vergleichbare Weise in einer nach anwendbarem Recht zulässigen Form geben. Das Anklicken des Symbols gilt als Anzeichen Ihrer eindeutigen und unwiderruflichen Annahme der Lizenz und der darin enthaltenen Klauseln und Bedingungen. In gleicher Weise gilt als Zeichen der eindeutigen und unwiderruflichen Zustimmung die Ausübung eines Rechtes, das in Artikel 2 dieser Lizenz angeführt ist, wie das Erstellen einer Bearbeitung oder die Verbreitung oder Zugänglichmachung des Werks oder dessen Vervielfältigungen. 

11.Informationspflichten
Wenn Sie das Werk verbreiten oder zugänglich machen (beispielsweise, indem Sie es zum Herunterladen von einer Website anbieten), müssen Sie über den Vertriebskanal oder das benutzte Verbreitungsmedium der Öffentlichkeit zumindest jene Informationen bereitstellen, die nach dem anwendbaren Recht bezüglich der Lizenzgeber, der Lizenz und ihrer Zugänglichkeit, des Abschlusses des Lizenzvertrags sowie darüber, wie die Lizenz durch den Lizenznehmer gespeichert und vervielfältigt werden kann, erforderlich sind.

12.Beendigung der Lizenz 
Die Lizenz und die damit eingeräumten Rechte erlöschen automatisch, wenn der Lizenznehmer gegen die Lizenzbedingungen verstößt. Ein solches Erlöschen der Lizenz führt nicht zum Erlöschen der Lizenzen von Personen, denen das Werk vom Lizenznehmer unter dieser Lizenz zur Verfügung gestellt worden ist, solange diese Personen die Lizenzbedingungen erfüllen. 
13.Sonstiges
Unbeschadet des Artikels 9 stellt die Lizenz die vollständige Vereinbarung der Parteien über das Werk dar. Sind einzelne Bestimmungen der Lizenz nach geltendem Recht nichtig oder unwirksam, so berührt dies nicht die Wirksamkeit oder Durchsetzbarkeit der Lizenz an sich. Solche Bestimmungen werden vielmehr so ausgelegt oder modifiziert, dass sie wirksam und durchsetzbar sind. Die Europäische Kommission kann weitere Sprachfassungen oder neue Versionen dieser Lizenz oder aktualisierte Fassungen des Anhangs veröffentlichen, soweit dies notwendig und angemessen ist, ohne den Umfang der Lizenzrechte zu verringern. Neue Versionen werden mit einer eindeutigen Versionsnummer veröffentlicht. Alle von der Europäischen Kommission anerkannten Sprachfassungen dieser Lizenz sind gleichwertig. Die Parteien können sich auf die Sprachfassung ihrer Wahl berufen.

14.Gerichtsstand
Unbeschadet besonderer Vereinbarungen zwischen den Parteien gilt Folgendes: 
—  Für alle Streitigkeiten über die Auslegung dieser Lizenz zwischen den Organen, Einrichtungen und sonstigen Stellen der Europäischen Union als Lizenzgeber und einem Lizenznehmer ist der Gerichtshof der Europäischen Union gemäß Artikel 272 des Vertrags über die Arbeitsweise der Europäischen Union zuständig; 
—  Gerichtsstand für Streitigkeiten zwischen anderen Parteien über die Auslegung dieser Lizenz ist allein der Ort, an dem der Lizenzgeber seinen Wohnsitz oder den wirtschaftlichen Mittelpunkt seiner Tätigkeit hat. 

15.Anwendbares Recht
Unbeschadet besonderer Vereinbarungen zwischen den Parteien gilt Folgendes: 
—  Diese Lizenz unterliegt dem Recht des Mitgliedstaats der Europäischen Union, in dem der Lizenzgeber seinen Sitz, Wohnsitz oder eingetragenen Sitz hat; 
—  diese Lizenz unterliegt dem belgischen Recht, wenn der Lizenzgeber keinen Sitz, Wohnsitz oder eingetragenen Sitz in einem Mitgliedstaat der Europäischen Union hat.

                      EUROPEAN UNION PUBLIC LICENCE v. 1.2
                      EUPL © the European Union 2007, 2016

This European Union Public Licence (the ‘EUPL’) applies to the Work (as defined
below) which is provided under the terms of this Licence. Any use of the Work,
other than as authorised under this Licence is prohibited (to the extent such
use is covered by a right of the copyright holder of the Work).

The Work is provided under the terms of this Licence when the Licensor (as
defined below) has placed the following notice immediately following the
copyright notice for the Work:

        Licensed under the EUPL

or has expressed by any other means his willingness to license under the EUPL.

1. Definitions

In this Licence, the following terms have the following meaning:

- ‘The Licence’: this Licence.

- ‘The Original Work’: the work or software distributed or communicated by the
  Licensor under this Licence, available as Source Code and also as Executable
  Code as the case may be.

- ‘Derivative Works’: the works or software that could be created by the
  Licensee, based upon the Original Work or modifications thereof. This Licence
  does not define the extent of modification or dependence on the Original Work
  required in order to classify a work as a Derivative Work; this extent is
  determined by copyright law applicable in the country mentioned in Article 15.

- ‘The Work’: the Original Work or its Derivative Works.

- ‘The Source Code’: the human-readable form of the Work which is the most
  convenient for people to study and modify.

- ‘The Executable Code’: any code which has generally been compiled and which is
  meant to be interpreted by a computer as a program.

- ‘The Licensor’: the natural or legal person that distributes or communicates
  the Work under the Licence.

- ‘Contributor(s)’: any natural or legal person who modifies the Work under the
  Licence, or otherwise contributes to the creation of a Derivative Work.

- ‘The Licensee’ or ‘You’: any natural or legal person who makes any usage of
  the Work under the terms of the Licence.

- ‘Distribution’ or ‘Communication’: any act of selling, giving, lending,
  renting, distributing, communicating, transmitting, or otherwise making
  available, online or offline, copies of the Work or providing access to its
  essential functionalities at the disposal of any other natural or legal
  person.

2. Scope of the rights granted by the Licence

The Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
sublicensable licence to do the following, for the duration of copyright vested
in the Original Work:

- use the Work in any circumstance and for all usage,
- reproduce the Work,
- modify the Work, and make Derivative Works based upon the Work,
- communicate to the public, including the right to make available or display
  the Work or copies thereof to the public and perform publicly, as the case may
  be, the Work,
- distribute the Work or copies thereof,
- lend and rent the Work or copies thereof,
- sublicense rights in the Work or copies thereof.

Those rights can be exercised on any media, supports and formats, whether now
known or later invented, as far as the applicable law permits so.

In the countries where moral rights apply, the Licensor waives his right to
exercise his moral right to the extent allowed by law in order to make effective
the licence of the economic rights here above listed.

The Licensor grants to the Licensee royalty-free, non-exclusive usage rights to
any patents held by the Licensor, to the extent necessary to make use of the
rights granted on the Work under this Licence.

3. Communication of the Source Code

The Licensor may provide the Work either in its Source Code form, or as
Executable Code. If the Work is provided as Executable Code, the Licensor
provides in addition a machine-readable copy of the Source Code of the Work
along with each copy of the Work that the Licensor distributes or indicates, in
a notice following the copyright notice attached to the Work, a repository where
the Source Code is easily and freely accessible for as long as the Licensor
continues to distribute or communicate the Work.

4. Limitations on copyright

Nothing in this Licence is intended to deprive the Licensee of the benefits from
any exception or limitation to the exclusive rights of the rights owners in the
Work, of the exhaustion of those rights or of other applicable limitations
thereto.

5. Obligations of the Licensee

The grant of the rights mentioned above is subject to some restrictions and
obligations imposed on the Licensee. Those obligations are the following:

Attribution right: The Licensee shall keep intact all copyright, patent or
trademarks notices and all notices that refer to the Licence and to the
disclaimer of warranties. The Licensee must include a copy of such notices and a
copy of the Licence with every copy of the Work he/she distributes or
communicates. The Licensee must cause any Derivative Work to carry prominent
notices stating that the Work has been modified and the date of modification.

Copyleft clause: If the Licensee distributes or communicates copies of the
Original Works or Derivative Works, this Distribution or Communication will be
done under the terms of this Licence or of a later version of this Licence
unless the Original Work is expressly distributed only under this version of the
Licence — for example by communicating ‘EUPL v. 1.2 only’. The Licensee
(becoming Licensor) cannot offer or impose any additional terms or conditions on
the Work or Derivative Work that alter or restrict the terms of the Licence.

Compatibility clause: If the Licensee Distributes or Communicates Derivative
Works or copies thereof based upon both the Work and another work licensed under
a Compatible Licence, this Distribution or Communication can be done under the
terms of this Compatible Licence. For the sake of this clause, ‘Compatible
Licence’ refers to the licences listed in the appendix attached to this Licence.
Should the Licensee's obligations under the Compatible Licence conflict with
his/her obligations under this Licence, the obligations of the Compatible
Licence shall prevail.

Provision of Source Code: When distributing or communicating copies of the Work,
the Licensee will provide a machine-readable copy of the Source Code or indicate
a repository where this Source will be easily and freely available for as long
as the Licensee continues to distribute or communicate the Work.

Legal Protection: This Licence does not grant permission to use the trade names,
trademarks, service marks, or names of the Licensor, except as required for
reasonable and customary use in describing the origin of the Work and
reproducing the content of the copyright notice.

6. Chain of Authorship

The original Licensor warrants that the copyright in the Original Work granted
hereunder is owned by him/her or licensed to him/her and that he/she has the
power and authority to grant the Licence.

Each Contributor warrants that the copyright in the modifications he/she brings
to the Work are owned by him/her or licensed to him/her and that he/she has the
power and authority to grant the Licence.

Each time You accept the Licence, the original Licensor and subsequent
Contributors grant You a licence to their contributions to the Work, under the
terms of this Licence.

7. Disclaimer of Warranty

The Work is a work in progress, which is continuously improved by numerous
Contributors. It is not a finished work and may therefore contain defects or
‘bugs’ inherent to this type of development.

For the above reason, the Work is provided under the Licence on an ‘as is’ basis
and without warranties of any kind concerning the Work, including without
limitation merchantability, fitness for a particular purpose, absence of defects
or errors, accuracy, non-infringement of intellectual property rights other than
copyright as stated in Article 6 of this Licence.

This disclaimer of warranty is an essential part of the Licence and a condition
for the grant of any rights to the Work.

8. Disclaimer of Liability

Except in the cases of wilful misconduct or damages directly caused to natural
persons, the Licensor will in no event be liable for any direct or indirect,
material or moral, damages of any kind, arising out of the Licence or of the use
of the Work, including without limitation, damages for loss of goodwill, work
stoppage, computer failure or malfunction, loss of data or any commercial
damage, even if the Licensor has been advised of the possibility of such damage.
However, the Licensor will be liable under statutory product liability laws as
far such laws apply to the Work.

9. Additional agreements

While distributing the Work, You may choose to conclude an additional agreement,
defining obligations or services consistent with this Licence. However, if
accepting obligations, You may act only on your own behalf and on your sole
responsibility, not on behalf of the original Licensor or any other Contributor,
and only if You agree to indemnify, defend, and hold each Contributor harmless
for any liability incurred by, or claims asserted against such Contributor by
the fact You have accepted any warranty or additional liability.

10. Acceptance of the Licence

The provisions of this Licence can be accepted by clicking on an icon ‘I agree’
placed under the bottom of a window displaying the text of this Licence or by
affirming consent in any other similar way, in accordance with the rules of
applicable law. Clicking on that icon indicates your clear and irrevocable
acceptance of this Licence and all of its terms and conditions.

Similarly, you irrevocably accept this Licence and all of its terms and
conditions by exercising any rights granted to You by Article 2 of this Licence,
such as the use of the Work, the creation by You of a Derivative Work or the
Distribution or Communication by You of the Work or copies thereof.

11. Information to the public

In case of any Distribution or Communication of the Work by means of electronic
communication by You (for example, by offering to download the Work from a
remote location) the distribution channel or media (for example, a website) must
at least provide to the public the information requested by the applicable law
regarding the Licensor, the Licence and the way it may be accessible, concluded,
stored and reproduced by the Licensee.

12. Termination of the Licence

The Licence and the rights granted hereunder will terminate automatically upon
any breach by the Licensee of the terms of the Licence.

Such a termination will not terminate the licences of any person who has
received the Work from the Licensee under the Licence, provided such persons
remain in full compliance with the Licence.

13. Miscellaneous

Without prejudice of Article 9 above, the Licence represents the complete
agreement between the Parties as to the Work.

If any provision of the Licence is invalid or unenforceable under applicable
law, this will not affect the validity or enforceability of the Licence as a
whole. Such provision will be construed or reformed so as necessary to make it
valid and enforceable.

The European Commission may publish other linguistic versions or new versions of
this Licence or updated versions of the Appendix, so far this is required and
reasonable, without reducing the scope of the rights granted by the Licence. New
versions of the Licence will be published with a unique version number.

All linguistic versions of this Licence, approved by the European Commission,
have identical value. Parties can take advantage of the linguistic version of
their choice.

14. Jurisdiction

Without prejudice to specific agreement between parties,

- any litigation resulting from the interpretation of this License, arising
  between the European Union institutions, bodies, offices or agencies, as a
  Licensor, and any Licensee, will be subject to the jurisdiction of the Court
  of Justice of the European Union, as laid down in article 272 of the Treaty on
  the Functioning of the European Union,

- any litigation arising between other parties and resulting from the
  interpretation of this License, will be subject to the exclusive jurisdiction
  of the competent court where the Licensor resides or conducts its primary
  business.

15. Applicable Law

Without prejudice to specific agreement between parties,

- this Licence shall be governed by the law of the European Union Member State
  where the Licensor has his seat, resides or has his registered office,

- this licence shall be governed by Belgian law if the Licensor has no seat,
  residence or registered office inside a European Union Member State.
