Since Sean asked:
Regarding guidelines for helpfiles, there are some on the swiki:
http://swiki.hfbk-hamburg.de:8888/MusicTechnology/517
Beyond this in general follow the existing formats, i.e.
Text in Helvetica 12 pt, code in Monaco 10 pt (Some older ones are in
12 pt; I propose we standardize to 10). Syntax colorize the code.
I propose we ashould stay with 9 pt monaco for now. Someday there
should be a scaleable SC font that looks good. 10 pt anti-aliased
monaco doesn't look very clear, at least to me.
