+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 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 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

+  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

+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided

+
+                     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 <http://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
+<http://www.gnu.org/licenses/>.

+Spreed Speak Freely
+===================
+
+The latest version of Spreed Speak Freely can be found on GitHub:
+
+  https://github.com/strukturag/spreed-speakfreely
+
+
+## Build prerequisites
+
+  - [Go](http://golang.org) >= 1.1.0
+  - [NodeJS](http://nodejs.org/)
+  - [Sass](http://sass-lang.com/)
+  - [Compass](http://compass-style.org/)
+  - [Babel](http://babel.pocoo.org/)
+  - [po2json](https://github.com/mikeedwards/po2json)
+  - make
+
+
+## Building
+
+  Go, Sass and NodeJS need to be in your $PATH.
+
+  ```bash
+  $ make
+  ```
+
+
+## Build seperately
+
+  Get Go external dependencies first with ``make get``.
+
+  ```bash
+  $ make styles
+  $ make javascript
+  $ make binary
+  ```
+
+
+## Server startup
+
+  ```bash
+  spreed-speakfreely-server [OPTIONS]
+  ```
+
+  Options
+
+    -c="./server.conf": Configuration file.
+    -cpuprofile="": Write cpu profile to file.
+    -h=false: Show this usage information and exit.
+    -l="": Log file, defaults to stderr.
+    -memprofile="": Write memory profile to this file.
+    -v=false: Display version number and exit.
+
+  An example configuration file can be found in server.conf.in.
+
+
+## Usage
+
+  Connect to the server URL and port with a web browser and the
+  web client will launch.
+
+
+## In place start for development
+
+  Copy the server.conf.in to server.conf.
+
+  Build styles, javascript and binary using make. Then run
+  ``./spreed-speakfreely-server``
+
+  The server runs on http://localhost:8080/ per default.
+
+  HTML changes and Go rebuilds need a server restart. Javascript
+  and CSS reload directly.
+
+
+## Production use
+
+  Spreed Speak Freely should be run through a SSL frontend proxy with
+  support for Websockets. Example configuration for Nginx can be
+  found in `doc/NGINX.txt`.
+
+  In addion for real work use one also needs a STUN/TURN server
+  configured with shared secret support.
+
+  See https://code.google.com/p/rfc5766-turn-server/ for a free
+  open source TURN server implementation.
+
+
+## Contributing
+
+1. "Fork".
+2. Make a feature branch.
+3. Make changes.
+4. Do your commits (run ``make fmt`` before commit).
+5. Send "pull request".
+
+## License

+               Spreed Speak Freely Channeling API v1.1.4
+            =================================================
+                        (c)2014 struktur AG
+
+The server provides a Websocket connection end point as channeling API to
+share peer information for peer to peer connectivity.
+
+
+Quick signaling overview
+
+  1. Establish websocket connection to /ws path of the
+     channeling server. Optionally, add a token as request paramete
+     t to reclaim an existing session (Example /ws?t=my-secret-token).
+
+  2. Server sends Self document after connection was established.
+
+  3. Send Hello document to the server.
+
+  -- Channeling API is now established --
+
+  4. Wait for incoming Offer and Candidate documents
+
+     4.a. Process incoming Offer and Candidate documents Sdp data by
+          submitting it to the peer connection implementation.
+
+     4.b. If received an Offer, send Answer document with your own peer
+          connection Sdp data as payload.
+
+     4.c. Send out Candidates if not already sent in the Offer Sdp data.
+
+  5. To initiate a call, get your peer connection Sdp data and send it
+     and Offer document with Sdp payload.
+
+     5.a. Send Offer.
+
+     5.b. Send Candidates if not already sent in the Offer Sdp data.
+
+     5.c. Wait for Answer and Candidates. When received put the Sdp data
+          into your peer connection implementation.
+
+  6. To close a call, send a Bye document.
+
+
+In general all documents are JSON documents.
+
+
+Sending vs receiving document data encapsulation
+
+  All documents sent to the channeling server need to be wrapped in their
+  own type once more for security reasons.
+
+    {
+        "Type": "Whatever",
+        "Whatever": { /* your document */ }
+    }
+
+    So any document you sent, you have to specify a Type key pointing
+    to the key where the real document is to be found.
+
+  Received documents are wrapped by a special Document which provides
+  additional information.
+
+    {
+        "From": "4",
+        "To": "5",
+        "Data": {}
+    }
+
+  The Data key contains the real Document.
+
+  Keys:
+
+    From : The sending side Id as known to the server (uint64). Use this Id
+           as To, to reply to things.
+    To   : The Id, the server send this Document to. Should be the same as
+           your current Self Id.
+    Data : Contains the payload.
+
+
+Special purpose documents for channling

+            "turns:213.203.211.154:443?transport=tcp"
+          }
+        },
+        "Stun": [
+          "stun:213.203.211.154:443"
+        ]
+    }
+
+    Self document is used by the server, to tell the client its own Id.
+
+    Keys:
+
+        Type   : Self (string)
+        Id     : Channel id for this connection (string)
+        Token  : Security token (string), to restablish connection with the same
+                 session. Pass the value as URL query parameter t, to the websocket URL.
+        Version: Server version number. Use this to detect server upgrades.
+        Turn   : Mapping (interface{}) to contain TURN server details, like
+                 urls, password and username. See
+                 http://tools.ietf.org/html/draft-uberti-behave-turn-rest-00
+                 and TURN REST API section in
+                 https://code.google.com/p/rfc5766-turn-server/wiki/turnserver
+                 for details.
+        Stun   : Array with STUN server URLs.
+
+    You can also send an empty Self document to the server to make the server
+    transmit a fresh Self document (eg. to refresh when ttl was reached). Please
+    note that you need to refresh before the ttl was reached - so add a grace
+    period like 10% to the refresh timeout.

+
+    Send an Alive document to the channeling server if you want to check if

+    check if nothing else was received from the channeling server for a
+    while.
+
+    The Alive value is a timestamp integer in milliseconds (unix time).
+
+
+Chat messages and status information
+
+  The chat is used to transfer simple messages ore more complex structures
+  using the Status sub key.
+
+  Chat (Send without time)
+
+    {
+        "Type": "Chat",
+        "Chat": {
+            "Message": "Some chat message"
+        }
+    }
+
+  Chat (Send without time and tell server not to loop send us our own mesasge)
+
+    {
+        "Type":"Chat",
+        "Chat":{
+          "Message":"hello",
+          "NoEcho":true
+        }
+    }
+
+    The NoEcho boolean key indicates that the client can display its own
+    messages directly without the need to receive it from the server. This
+    is the preferred client mode.
+
+  Chat (Received with time)
+
+    {
+        "Type": "Chat",
+        "Chat": {
+            "Message": "Some chat message",
+            "Time": "2006-01-02T15:04:05Z",
+            "Status": null
+        }
+    }
+
+  Chat typing state
+
+    {
+        "Message": "",
+        "Time": "2013-11-20T16:31:34+01:00",
+        "Status": {
+            "Typing": "start"
+        }
+    }
+
+    The typing state can either be "start" or "stop".
+
+  Chat with file sharing information
+
+    {
+        "Message": "File",
+        "Time": "2013-11-20T16:28:42+01:00",
+        "Status": {
+            "FileInfo": {
+                "chunks": 450,
+                "id": "file_null_MTM4NDk2MTA1M3xFd3dBRUxGZ0NYZUxqdWtBS2xPUUpYYURVblE9fDpVXfnE3KNz-Eq_I0zmi8mCX_OzP1mPSas6lC2BjhCI_1",
+                "name": "audio.wav",
+                "size": 26959472,
+                "type": "audio/wav"
+            }
+        }
+    }
+
+    The id of the FileInfo struct is the token which can be used to create
+    a token peer connection for file transfer. It is up to the UI if the
+    message is shown or not. For file transfer information the message is
+    always "File".
+
+  Chat message deliver status extensions
+
+    Send chat messages as normal, but add the "Mid" field which is a
+    client generated unique id to identify this single message. All status
+    messages for this message are sent back with this Mid. Whenever a Mid
+    is present in the Chat document, the server will trigger Status messages
+    automatically. Mid is completely optional. Only add it when the client
+    can handle it. Whenever a Status message is sent which should not trigger
+    another Status message, make sure to add the Mid below Status document
+    and not directly below Chat.
+
+    Generate the Mid from a secure random number generator to make it unique
+    and sufficiently unguessable.
+
+    Also make sure you have implemented the NoEcho client chat feature as
+    specified above.
+
+    Send message:
+
+    {
+      "Type":"Chat",
+      "Chat":{
+        "To":"MTM5MDEzMTEyMXxFd3dBRU1qeFJ1OW9jTllTdndjUjRnbzZ4dk09fFtAr3XSgyr9U9qo-xU-dOvcs5t-h2ANll7sqKKy-ov6",
+        "Type":"Chat",
+        "Chat":{
+          "Mid":"346c7d6e2989dca262be2c0a6a29eba2",
+          "Message":"test",
+          "NoEcho":true
+        }
+      }
+    }
+
+    Receive sent status back (generated by channeling server). In peer to peer
+    chat the client needs to trigger this itself.
+
+    {
+      "Type":"Chat",
+      "Chat":{
+        "Mid":"346c7d6e2989dca262be2c0a6a29eba2",
+        "Status":{
+          "State":"sent"
+        }
+      }
+    }
+
+    Receive delivered status from receiving client. The Mid in receiving client
+    generated Status messages is below the Status key, to avoid another round
+    of Status messages triggered by the Server. This message needs to be
+    triggered by the client whenever a message whith an Mid was received.
+
+    {
+      "Type":"Chat",
+      "Chat":{
+        "Time":"2014-01-19T22:31:00+01:00",
+        "Status":{
+          "Mid":"346c7d6e2989dca262be2c0a6a29eba2",
+          "State":"delivered"
+        }
+      }
+    }
+
+    Receive read status of messages by batch mode Mid list. This needs to be
+    triggered by the client whenever a user has seen a particular message. As
+    this usually becomes true for multiple Mid messages this is implemented as
+    Mid list. Touch, mouse or text input qualify as indication of read status.
+
+    {
+      "Type":"Chat",
+      "Chat":{
+        "Time":"2014-01-19T22:29:05+01:00",
+        "Status":{
+          "SeenMids":[
+            "346c7d6e2989dca262be2c0a6a29eba2"
+          ]
+        }
+      }
+    }
+
+
+  Request being called from audio mixer
+
+    {
+        "Type": "Chat",
+        "Chat": {
+            "Message": null,
+            "Status": {
+                "type": "conference",
+                "id": "my-conference-room"
+            }
+        }
+    }
+
+    This can be sent to any participant that has a "Status" containing the "isMixer"
+    flag with a "true" value. The peer will then try to establish a peer connection
+    to the caller which it needs to pick up to join an audio conference.
+
+
+Data channel only messages
+
+  Each of the peer connections also create a data channel with the label
+  "default". The party sending the offer also creates this data channel.
+  The default data channel can be used to send all of the above messages
+  directly to the peer, bypassing the channeling server. Additionally some
+  message documents are only sent/received via a such data channel and are
+  never sent through the channeling server.
+
+  Talking (data channel only)
+
+    {
+        "Type": "Talking",
+        "Talking": true
+    }
+
+    The talking state sent by a given user as boolean value in "Talking"
+    key (true, false).
+
+  Screenshare (data channel only)
+
+    {
+        "Type": "Screenshare",
+        "Screenshare": {
+            "id": "screenshare_token"
+        }
+    }
+
+    The id is the token to be used to establish a token peer connection
+    to the user which sent the Screenshare document.
+
+
+Conferences and how to use them
+
+  There is a new data document "Conference" to share information about
+  conference participants. It is to be sent to the server, containing an Id
+  for this conference, and the user ids for the conference participants.
+
+  Once a client recieves such a Conference document, it has to check state
+  for all User ids in the Conference document Conference list like this:
+
+    - If not in a call already -> ignore.
+    - If in a call, and own Id is not in the Conference list -> ignore.
+    - Loop through all Ids, string compare the Id with own Id, and if result
+      is -1 (not 0 or 1), send Offer to this Id if not got a call with this
+      Id already.
+
+  Conference offers are the same as normal Offers, with one additional field
+  "_conference" inside the Offer.Offer mapping for the Conference Id.
+

+            }
+        }
+    }
+
+    This sends an Offer to Id "5" for conference "the-conference-id".
+
+    Whenever an offer is received for a Conference id, and the client
+    already is in a call with matching conference id, all subsequent Offers
+    for this Conference Id should be accepted automatically.
+
+  Conference information
+
+    {
+        "Type": "Conference",
+        "Id": "the-conference-id",
+        "Conference": [
+            "user-a-id",
+            "user-b-id"
+        ]
+    }
+
+    Use Conference documents, to create a conference / add new users to a
+    conference.
+
+    The Id is to be generated by the client and needs to be unique. It
+    should ne the Id of the client creating the conference (as received from
+    Self document) plus some random string, and both hashed together. Create
+    it as secure and unpredictable as possible.
+
+    The Conference list inside the Conference document, does contain ids
+    (string) to be added to the conference. You should always send all Ids
+    including those already in the conference and the ones to be added to
+    the conference.
+
+
+Additional token based peer connections
+
+  In addition to the normal audio/video peer connections multiple other
+  token trust peer connections can be estabished to any number of peers. A
+  existing peer connection is not required. Offers for a token based peer
+  connection can be always recevied.
+
+  In general a token is shared through the channeling server or another
+  peer connection first. Whoever has that exact token is trusted and can
+  establish (== send an offer) to establish a peer connection for exactly
+  this token to a peer which is expected also to know this token. The peer
+  is then expected to answer the offer automatically and pass all the
+  control of this token peer connection to the token registrant ui
+  component (eg. for file sharing or screen sharing).
+
+  In addition to each token which is present as key _token in the payload
+  mapping there also needs to be an id as key _id, which identifies exactly
+  this connection. The _id is required to match multiple connections
+  between the same two peers.
+
+  The additional keys _token and _id need to be added to all payload data
+  keys for Offer, Answer and Candidate.
+
+  Example token Offer

+
+  Token peer connections als have a default data channel with label
+  "default" which is used for feature wise communication like flow control
+  in file sharing.
+
+
+File sharing data channel protocol
+
+  File sharing uses a token peer connection for transferring the data
+  through the default data channel with label default.
+
+  There are the following two supported message types which are received
+  for file sharing on such a data channel:
+
+    ArrayBuffer
+
+      Payload data in the following format (version 0):
+        1 byte UInt8  : Version.
+        3 byte        : Reserved for future use.
+        4 byte UInt32 : Chunk sequence number.
+        4 byte UInt32 : Chunk Crc32 checksum.
+        ... bytes     : Payload data.
+
+    String
+
+      JSON chunk request
+
+        {
+            "m": "r",
+            "i": 0
+        }
+
+        m is the mode. Currently only "r" is known to request chunks.
+        i is the chunk sequence number to request (integer).
+
+      Whenever you want the peer to send a chunk, request it by sending a
+      JSON chunk request over the data channel with the sequence which
+      should be transmitted. The current web implementation requests chunks
+      sequentially, and waiting for each chunk to be complete before
+      sending the request for the next one.
+
+
+End of Channeling API.

+A few notes on Nginx configuration
+
+  In general Nginx with websocket support is required 
+  (I am using Nginx 1.4). It should work with Nginx 1.3 too.
+
+  Add the following to your Nginx server section:
+
+    location / {
+	proxy_pass http://localhost:8090;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection $connection_upgrade;
+	proxy_set_header X-Forwarded-Proto $scheme;
+	proxy_set_header Host $http_host;
+	proxy_set_header X-Real-IP $remote_addr;
+	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    }
+
+  This is using a map to provide the Upgrade and Connection 
+  headers to the backend server. You need to add this map to 
+  the http section of your server:
+
+    map $http_upgrade $connection_upgrade {
+        default upgrade;
+        ''      close;
+    }
+
+  Also make sure that you have the general proxy configuration 
+  like this in place:
+
+	proxy_buffering             on;
+	proxy_ignore_client_abort   off;
+	proxy_redirect              off;
+	proxy_connect_timeout       90;
+	proxy_send_timeout          90;
+	proxy_read_timeout          90;
+	proxy_buffer_size           4k;
+	proxy_buffers               4 32k;
+	proxy_busy_buffers_size     64k;
+	proxy_temp_file_write_size  64k;
+	proxy_next_upstream error timeout invalid_header http_502 http_503 http_504;
+
+  Thats it.
