Courtesy of NPSL, the wonderful people that I work for, some of my work is available at no extra charge. There are some details of bits lying around, but first you need to know how to get at it. It’s all in a subversion repository which you can browse at:
http://www.blushingpenguin.com:8080/viewcvs
You can download tarballs from there.
Then for checking out the code (all of it, or change the path):
svn co svn://blushingpenguin.com/usr/local/svnroot/trunk/
or
svn co http://www.blushingpenguin.com:8080/svn/trunk/
should do.
