Hallo!
ATM the help path system does not work for Pd-Extended (at least on linux). All the helpfiles are installed in /5.reference/externalname, but pd automatically searches in extra/externalname.
So there are 2 possibilities to fix this:
1) we also have to add all /5.reference/externalname in libdir.pd_linux to the help path
2) why don't we install all the helpfiles simply in extra/externalname ? Then all this would be no problem and I also find it much clearer this way ...
So please anyone feel free to comment on this - then I will implement it.
LG Georg
