The easiest way of dowloading the source code is via CVS from cvs.sourceforge.net as an anonymous user; Follow the instructions from sourceforge and substitute the module with sourcecode to access the latest versions of our source code. In case just a particular component or file from CSTK is needed, a web-based CVS database containing all source code can be accessed as well (courtesy of Sourceforge.net). Compressed packages can also be found on this site for dowload, but they are almost guaranteed to be old and near-obsolete.
These are the commands to check out the entire source code collection of CSTK:
cvs -d:pserver:firstname.lastname@example.org:/cvsroot/cstk login
cvs -z3 -d:pserver:email@example.com:/cvsroot/cstk co -P sourcecode
Simply press Enter when the system asks for a password. Instead of entering these commands in a terminal or console, you can also use your cvs client of choice to check out the CSTK source code.
If you have been added as a Sourceforge developer to CSTK by one of the current developers, you
can also log in using your username:
cvs -z3 -d:ext:firstname.lastname@example.org:/cvsroot/cstk co -P sourcecode
