% DownloadAdditionsForLinux(targetdirectory [, flavor]);
%
% Install missing Matlab or Octave mex files for older versions of the
% Psychtoolbox, as provided by some Linux distributions, e.g., Ubuntu 12.10
% or (as of April 2013) 13.04.
%
% It needs Subversion to be installed on your machine (sudo apt-get install
% subversion).
%
% You *do not need* this function if you downloaded Psychtoolbox from its
% home-site via DownloadPsychtoolbox(), or if you install Psychtoolbox from
% the NeuroDebian repository. If you install from NeuroDebian, simply
% install these packages:
%
% For Matlab:
%
% Basic Mex files: sudo apt-get install matlab-psychtoolbox-3
% Datapixx and Eyelink: sudo apt-get install matlab-psychtoolbox-3-nonfree
%
% For Octave, if you want to use the Datapixx or Eyelink functions:
% sudo apt-get install octave-psychtoolbox-3-nonfree
%
% However, some Linux distributinos bundle Psychtoolbox as part of their
% standard package repository, e.g., Ubuntu 12.10 and 13.04, and they
% provide outdated packages (as of April 2013) which require you to run
% this script manually after each installation or update in order to
% retrieve mex files for Matlab, or the Datapixx and Eyelink mex files for
% octave.
%
% You can call this function from within Matlab, providing the full path to
% a directory. The function will create a new folder PsychtoolboxAddOns
% inside that directory and add it to your path. The add on files will be
% downloaded from the Psychtoolbox main repository and stored there.
%
% After this function successfully completes, your Psychtoolbox should work
% with Matlab on Linux as well.
%
% If you call this function from within Octave, it will download only a few
% additional addon files for the Octave Psychtoolbox. Currently the only
% added files are the Eyelink mex files for SR-Research Eyelink
% Gazetrackers, and the Datapixx mex file for VPixx Inc. products.
%
% This function should eventually become obsolete when the regular mainstream
% Linux distributions update their packaged versions of Psychtoolbox.
%
% History:
% 29.09.2011 mk Written.
% 30.11.2011 mk Bugfix: Get from trunk, not beta.
% Bugfix: On Linux + Octave, get Datapixx.mex as well.
%
% 27.05.2012 mk - Strip backwards compatibility support to Matlab pre-R2007a.
% - Strip support for 'stable' / 'unsupported' flavors et al.
% - Change location of SVN repository to our SVN frontend for GIT:
% https://github.com/Psychtoolbox-3/Psychtoolbox-3
%
% 16.04.2013 mk - Rename to DownloadAdditionsForLinux. Make clear that
% this is no longer needed for NeuroDebian packages, but
% only for downloads from mainstream Ubuntu 12.10 &
% 13.04.
% - Replace textread() by textscan() on R2012a and later.
% - Use javaclasspath.txt instead of classpath.txt on
% R2013a and later.
