UseTheSource - How to access the Psychtoolbox source code.

If you are interested in the source code for the C language
modules of Psychtoolbox (i.e., the MEX file extensions
like Screen, WaitSecs, GetSecs, PsychHID, ...) then use the
following procedure.

The Psychtoolbox source code is stored in a Git code repository at
GitHub.

1. Open a Unix terminal window on OS-X or Linux or a NT command
   shell on M$-Windows.

2. Use the "svn" commandline tool to download source code. On
   OS-X or Linux, the svn tool is usually stored in the
   /usr/local/bin directory, you may want to add this to your
   PATH. On Windows, the svn client should be already in your
   %PATH%

3. The following command would download the current development branch of
   the full PTB distribution into the subdirectory /Users/kleinerm/MyPTB :

   svn checkout https://github.com/Psychtoolbox-3/Psychtoolbox-3/ /Users/kleinerm/MyPTB/

   This command would download the full 'beta' distribution instead,
   which corresponds to the most recent official, tested, production release:

   svn checkout https://github.com/Psychtoolbox-3/Psychtoolbox-3/branches/beta/ /Users/kleinerm/MyPTB/

   Inside the /Users/kleinerm/MyPTB folder you would see the following
   subfolders:

   Psychtoolbox/ -- The regular Psychtoolbox folder.
   managementools/ -- Miscellaneous scripts for managing PTB releases.
   PsychSourceGL/ -- The C source code for Psychtoolbox.

   Inside PsychSourceGL you will find everything you need to understand
   or to modify Psychtoolbox inner working if you are brave and patient
   enough ;-)

trunk - The code that is currently under development. May or may not
compile and work at any given point in time, may or may not
be consistent. For developers and early testers only! This is
a view onto the GitHub Git "master" branch.

beta - Source code corresponding to the current 'beta' release, derived
from 'trunk'. This is what normal users should use, because
it is somewhat tested.

If you type the command "PsychtoolboxVersion" in Matlab or Octave, it
will tell you the flavor (trunk or beta) and SVN revision number of
your currently installed PTB distribution. This allows you to locate
the corresponding code in the GIT/SVN repository.

Be aware that you can only download code from the repository. If you
want to participate in PTB's development contact Mario Kleiner or
David Brainard for instructions. Make yourself familiar with Git if
you want to do serious work.

An even more recent view of current development can be found on
GitHub, where our master and experimental branches are hosted. If you
intend to contribute to C code development or other complex parts of
the software, we will require you to use git instead of Subversion and
you will work with the git repository at GitHub.

For almost all source code, i.e., unless otherwise stated in the
source files themselves or accompanying documentation, the MIT license
applies. See the file License.txt in the Psychtoolbox root folder for
more details.

Components & Libraries which are not covered by the MIT license, but
other MIT compatible free software licenses will carry individual
descriptions of their licenses inside the source files or in
accompanying license files within the corresponding subfolders. Such
libraries are usually contained in the PsychSourceGL/Cohorts/
subdirectory of the distribution.

Good luck and "Use the source" (Master Yoda).
