Most of osFree's files are currently available through Sourceforge's SVN. osFree is currently a deep alpha stage project. You can test some packages and/or you can browse the sources. You can also access SVN directly at https://osfree.svn.sourceforge.net/svnroot/osfree/trunk through your preferred SVN client. Sourceforge has more information about accessing it through SVN. However we have information about it as well.
There is our Demo CD available too.
