Apparently the only way is to get the source code through Subversion. From the Open Komodo Development README:
The Open Komodo sources are kept in a Subversion repository
hosted at the openkomodo.com site. Read-only public access
is available via:
svn co http://svn.openkomodo.com/repos/openkomodo/trunk openkomodo
For Windows, using TortoiseSVN (see
Practical guide to subversion on Windows with TortoiseSVN
for installation, setup and use):
Right click on <folder to receive the source code>/SVN
Checkout/set "URL of repository" to
"http://svn.openkomodo.com/repos/openkomodo/trunk"
The result was 15164 files in 6120 folders, 138 MB transferred, 348 MB on disk.
Including 93 C files, 138 C++ files and 971 Python files.
The source code files can also be browsed online.
