This document presents What licence information on ConTeXt, suits best for a TeX like system is a matter oftaste. Personally we dislike any licence that needs more than a macro packagewritten in few pages of dense legal code to get the typographical programming language message accross. A TeX. This documentrelated system like ConTeXt is ''not'' an installation manuala hybrid of programs, scripts and/or macro code as well as documentation and sample code, includinggraphics. For installation TeX related systems also have a long standing traditionof providing support structures for users. In order to makesupport feasable, a TeX based system like ConTeXt assumes acertain logic and itsstructure in the way the related files areaccompanying programs we refer to named and organized in a tree structure. Even a small change inone of the following documents: elements may let such a system behave differently thanmanuals suggest. Swap a font, change some style defaults, leaveout some pieces, and users may end up in confusion. A licencedoes not give a user any guarantees!

=== Introduction ===First of all, what is ConTeXt? It's just a bunch of macros,written in TeX and METAPOST, meant for typesetting documents. Themacros are accompanied by some scripts, written in Perl (mainlythe older scripts) Ruby (the official ones) and Lua (for embeddedusage). The ConTeXt distribution comes with a few fonts, filesthat help manage resources (e.g. map files), as well aspatterns (based on official ones, so this is a derived work). The ConTeXt distribution is packaged in a zip file organized in the tds structure. cont-tmf.zip The main distribution. cont-img.zip A few extra resources. cont-ext.zip Third party modules. When we talk about ConTeXt we also mean its graphical companionMetaFun and foXet, an xml related product. All these are includedin the main distribution archive. The documentation can bedownloaded from our website, one of its mirrors, the TeXcollection as distributed by TeX user groups. For some manuals,source code is available in a subversion repository. Thearchives are also kept on ctan.

'''[1.2]''' The ConTeXt distribution includes TeX macro files as well as
some utility programs written in Perl, Perl/Tk, and Ruby as well as
graphic macros written in the METAPOST language. The same conditions
apply to all files.

All kinds of comment from<div style="color:gray;">users The GNU General Public License is welcomed and will be taken seriouslya Free Software license. When we talk aboutLike any Free Software ConTeXtlicense, we refer it grants to you the version as distributed by Pragma ADE anddescribed in the official reference manual. four following freedoms:

'''[2.6]''' For special purposes, not covered by existing functionality,
users can write their own extensions. ConTeXt provides hooks into the
core routines. These are documented in the source code.
'''[2.7]''' ConTeXt is available for free for everyone who want to useit. Distributors are free to choose between You may exercise the latest officialfreedoms specified here provided that you complyrelease and with the (in most cases stable) beta versionexpress conditions of this license. The principal conditionsare:
'''[2You must conspicuously and appropriately publish on each copydistributed an appropriate copyright notice and disclaimer of warrantyand keep intact all the notices that refer to this License and to theabsence of any warranty; and give any other recipients of the Programa copy of the GNU General Public License along with the Program.8]''' Experimental, and thereby potentially non-stable, versions asAnywell as certain dedicated modules, will translation of the GNU General Public License must be distributed under differentaccompanied byconditionsthe GNU General Public License.

'''[3.3]''' The official version (i.e. the original zipped archiverecognized by the prefix cont-) may only be redistributed as a wholeand under this licence. === Recommendations ===
'''[3.4]''' This licence does not automatically apply Here are a few recommendations in case you want to third partydistribute, extendextensions.of embed ConTeXt in applications:
=== Third party developments ===* You can best leave the code base untouched. Most of ConTeXt provides hooks and it's relatively easy to overload code. Leave the lower level system code untouched: changes may backfire when you update. Asking for more hooks is the best way to go.
'''[4* Put your own code in the right subpaths, i.e. modules approved by the development team under <tt>.../third</tt>, and styles and whatever else under <tt>.../user</tt>.1]''' This sections way your code will not introduce limitations in use thatconflict interfere with the gnu general public licenceexisting code and updating will give less problems. We only want to makesure Keep in mind that TeX systems have their own way and order in locating files, and the average user will get the ConTeXt they expect and thatwe can continue to support users efficientlyload order often matters.
'''[4* Be original.3]''' Keywords and command names should conform to the already definedones and therefore not clash with existing functionalityThe whole idea behind ConTeXt is that you can write your own styles. An exampleof extending On the user interface can be seen in ConTeXt mailing list as well as on the ppchTeXmoduleWiki there are enough advanced users to help you make a start.
'''[4* The scripts can best be called using texmfstart.6]''' We strongly advice users who write their own macros for ConTeXt,to package them This lessens dependencies on the location in document specific environments or third partymodules (prefixed by t-)the tree and ensures upward compatibility. It also prevents clashes with similary named scripts.
'''[4* Some scripts depend on each other.7]'Don'' Users may not change t mess around with the official distribution existing functionality and redistributethat changed version as official. This will ensure the integrity names ofConTeXt. Local settings cq. bug fixes can be added in the filescont-sys scripts and cont-new. Distributers may add configuration settings tocont-usr and cont-systhen feed them back into the standard distributions.
'''[4.8]''' When adapted versions of ConTeXt are distributed, these versionsmust contain the original distribution as a separate item. The runtimeversions (format files) must have different names and changed filesmust have an additional \writestatus message, expressing thatsomething is changed. The rationale behind this is that some modulesare generic, and are sometimes distributed on request separately. Whendistributing self contained modules and styles, a full distribution oforiginals is not required. === Documents ===
'''[4.9]''' Because many TeX systems support recursive directory search,those who write extensions or change files, must make sure that theoriginal ConTeXt does not suffer from loading the wrong files. Werealize that this The documentation is not always easy, but please keep in mind thatthere are many users who cannot sort out these problems. Together wemust guarantee that when users want to run original ConTeXt, nothingunexpected is loaded, because it makes support nearlyimpossible. provided under another Creative Commons licence

=== Preamble Introduction ===
In addition you may order to satisfy those responsible for distributing ConTeXt,we need to choose a licence that makes them feel comfortable.Unfortunately we don't feel that comfortable with a licence thatdoes not provide the guarantees that a system will not be adaptedin such ways that the advertised behaviour changes. On the otherhand, it is the introduction responsibility of those distributing and/or referencemanualextending the system to make sure that this does not happen. There are more documentsHowever, but you need only these to users should not automatically assume that what they getstarted. Unless you are going to change and redistribute ConTeXtshipped is the same as the original, youwhich is why we stress thatcan quit reading nowsupport (from our side) will only be given on unaltered systems.
