Personally +we dislike any licence that needs more than a few pages of dense legal code to +get the message across. A \TEX\ related system like \CONTEXT\ is a hybrid of +programs, scripts and|/|or macro code as well as documentation and sample code, +including graphics. \TEX\ related systems also have a long standing tradition of +providing support structures for users. In order to make support feasible, a +\TEX\ based system like \CONTEXT\ assumes a certain logic and structure in the +way the related files are named and organized in a tree structure. Even a small +change in one of the elements may let such a system behave differently than +manuals suggest. Swap a font, change some style defaults, leave out some pieces, +and users may end up in confusion. A licence does not give a user any guarantees! + +In 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 that does not provide the guarantees that a +system will not be adapted in such ways that the advertised behaviour changes. On +the other hand, it is the responsibility of those distributing and extending the +system to make sure that this does not happen. However, users should not +automatically assume that what they get shipped is the same as the original, +which is why we stress that support (from our side) will only be given on +unaltered systems. + +First of all, what is \CONTEXT ? It's just a bunch of macros, written in \TEX\ +and \METAPOST, meant for typesetting documents. The macros are accompanied by +some scripts, written in \PERL\ (mainly the older scripts) \RUBY\ (also older +ones) and \LUA\ (the current fashion). The \CONTEXT\ distribution comes with a +few fonts, files that help manage resources (e.g.\ map files needed for \MKII), +as well as patterns (based on official ones, so this is a derived work). + +The \CONTEXT\ distribution is packaged in a zip file organized in the \TDS\ +structure. + +\starttabulate[|lT|p|] +\NC \type {cont-tmf.zip} \NC the main distribution that has all relevant files \NC \NR +\NC \type {cont-tst.7z} \NC a bunch of test files that can also serve as examples \NC \NR +\NC \type {cont-mpd.zip} \NC a \METAPOST\ to \PDF\ converter (not needed in \CONTEXT) \NC \NR +\NC \type {cont-ppc.zip} \NC a macro package for typesetting chemistry (not needed in \CONTEXT) \NC \NR +\NC \type {cont-sci.zip} \NC configuration files for using \CONTEXT\ in the \SCITE\ editor \NC \NR +\stoptabulate + +There are two flavours of \CONTEXT: \MKII\ and \MKIV. The first one is frozen and +will not be extended. It runs on top of \PDFTEX\ or \XETEX. The \MKIV\ version is +actively developed and runs on top of \LUATEX\ (an engine that is developed +alongside \CONTEXT\ but that can also be used for other macro packages). + +The documentation can be downloaded from our website or the Wiki. Some manuals +ship with source code. We might ship more source code but only when the source is +stable and clean and can serve as an example. + +That said, what licence does apply? We need to distinguish between things that +resemble a program on the one hand and documentation on the other hand. We +(currently) use a different licence for either of them. + +\stopsubject + +\startsubject[title={The Code}] + +The program code (i.e. anything not under the \type {/doc} subtree) is +distributed under the + +\startnarrower +\goto{Creative Commons GNU GPL}[url(gpl-simple)] +\stopnarrower + +For practical purposes distributers may also choose the \LATEX\ project licence, +which is considered to be a bit more \TEX\ friendly. (BSD alike licences, the +Ruby Licence and the Apache are all licences that apply well for \CONTEXT.) + +In practice, users may forget about the legal part, if only because I haven't +even read (and understood) it completely myself, so let's stick to what Creative +Commons makes of it: + +\startcolor[blue] +The GNU General Public License is a Free Software license. Like any Free Software +license, it grants to you the four following freedoms: + +\startitemize + \startitem + The freedom to run the program for any purpose. + \stopitem + \startitem + The freedom to study how the program works and adapt it to your needs. + \stopitem + \startitem + The freedom to redistribute copies so you can help your neighbour. + \stopitem + \startitem + The freedom to improve the program and release your improvements to the + public, so that the whole community benefits. + \stopitem +\stopitemize + +You may exercise the freedoms specified here provided that you comply with the +express conditions of this license. The principal conditions are: + +You must conspicuously and appropriately publish on each copy distributed an +appropriate copyright notice and disclaimer of warranty and keep intact all the +notices that refer to this License and to the absence of any warranty; and give +any other recipients of the Program a copy of the GNU General Public License +along with the Program. Any translation of the GNU General Public License must be +accompanied by the GNU General Public License. + +If you modify your copy or copies of the program or any portion of it, or develop +a program based upon it, you may distribute the resulting work provided you do so +under the GNU General Public License. Any translation of the GNU General Public +License must be accompanied by the GNU General Public License. + +If you copy or distribute the program, you must accompany it with the complete +corresponding machine-readable source code or with a written offer, valid for at +least three years, to furnish the complete corresponding machine-readable source +code. + +Any of these conditions can be waived if you get permission from the copyright +holder. + +Your fair use and other rights are in no way affected by the above. +\stopcolor + +\stopsubject + +\startsubject[title={Recommendations}] + +Here are a few recommendations in case you want to distribute, extend of embed +\CONTEXT\ in applications: + +\startitemize + +\startitem + 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. +\stopitem + +\startitem + Put your own code in the right subpaths, i.e.\ modules approved by the + development team under \type {.../third}, and styles and whatever else under + \type {.../user}. This way your code will not interfere with existing code + and updating will give less problems. Keep in mind that \TEX\ systems have + their own way and order in locating files, and the load order often matters. +\stopitem + +\startitem + Don't copy styles and change a few lines, but load the base one and + built|/|patch on top of that. In the end you may benefit from improvements to + the base style. +\stopitem + +\startitem + Be original. The whole idea behind \CONTEXT\ is that you can write your own + styles. On the \CONTEXT\ mailing list as well as on the Wiki there are enough + advanced users to help you make a start. +\stopitem + +\startitem + Don't hesitate to submit bugs reports and ask for extensions. It may even be + that what you want is already present but yet undocumented. +\stopitem + +\startitem + If things don't work as expected, check to what extend your system matches + the (more or less) standard. We provide so called minimal \CONTEXT\ trees + that can serve as a reference. Because \CONTEXT\ evolves, make sure your + system is up to date. The \CONTEXT\ garden provides ways to install and + update the standard distribution. +\stopitem + +\startitem + The scripts can best be called using \type {mtxrun}. This lessens dependencies + on the location in the tree and ensures upward compatibility. It also prevents + clashes with similar scripts. +\stopitem + +\startitem + Some scripts depend on each other. Don't mess around with the existing + functionality and names of the scripts and then feed them back into the + standard distributions. +\stopitem + +\stopitemize + +\stopsubject + +\startsubject[title={Documents}] + +The documentation is provided under another Creative Commons licence + +\startnarrower + \goto{Attribution NonCommercial ShareAlike}[url(byncsa-simple)] +\stopnarrower + +This one says: + +\startcolor[blue] +You are free: + +\startitemize + \startitem to copy, distribute, display, and perform the work \stopitem + \startitem to make derivative works \stopitem +\stopitemize + +{\sc Attribution:} You must attribute the work in the manner specified by the +author or licensor. + +{\sc NonCommercial:} You may not use this work for commercial purposes. + +{\sc Share Alike:} If you alter, transform, or build upon this work, you may +distribute the resulting work only under a license identical to this one. + +\startitemize + \startitem + For any reuse or distribution, you must make clear to others the license + terms of this work. + \stopitem + \startitem + Any of these conditions can be waived if you get permission from the + copyright holder. + \stopitem +\stopitemize + +Your fair use and other rights are in no way affected by the above. +\stopcolor + +The non||commercial part is mostly a safeguard. We don't mind if user groups +distribute printed copies, publish (parts of) manuals and|/|or if authors use +example code in manuals and books about \CONTEXT. + +If you distribute \CONTEXT\ and related software on electronic media as part of +\TEX\ distributions (either or not for money), you may also distribute the +manuals and their sources in electronic form, preferable as provided by the +maintainers of \CONTEXT. + +Keep in mind that logos and cover designs are not meant to be copied. We provide +the source code for some manuals, but we don't always provide all graphics and +other resources. For instance, in some manuals we use commercial fonts and you +have to buy those yourself. + +We provide the typeset manuals at our website. Those are the official ones. We +appreciate it if you do not to distribute manuals compiled on your own system as +substitutes. The manuals are a showcase for what \CONTEXT\ provides.
