The CLPython source code is stored in a cvs repository at Franz. Until now the cvs module was named "python". The module has now been renamed to "clpython", the official name of this project.
To retrieve the code under the proper module name:
cvs -d :pserver:cvspublic@cvspublic.franz.com:/cvs-public login (use password: cvspublic) cvs -d :pserver:cvspublic@cvspublic.franz.com:/cvs-public checkout clpython
Of course these instructions are also on http://trac.common-lisp.net/clpython
There is more reorganization coming up, in terms of directory structure and packages. I'll describe that when it is submitted, in a few days.
