Hi, Aah now I've found it. The problem is what I was always going to the "official" documentation: https://www.gnu.org/software/apl/apl.html Otherwise I have to not only checkout sources from SVN, but also keep them checked out and browse for different sources of information (and of course I didn't since I assumed the link above is an official manual which should contain all the necessary information).
