Sometimes it is difficult to find the location of opensource software. It is not always available where you would look for it. I have been looking for the source code location of Adept for a while now (well, I haven’t wanted it so badly that I was willing to install Ubuntu.) Currently the only source copies are in KDE svn. Get adept from anonomous KDE svn this way:
svn co svn://anonsvn.kde.org/trunk/playground/sysadmin/adept
