[Gridflow-dev] problems with doc/5.reference/gridflow/*.pd (pd-0.39-test6)

[Claude Heiland-Allen]

Hi all,

Trying to open Help->Browser...->5.reference/gridflow/@checkers.pd fails 
partly with current gridflow cvs and pd-0.39-test6, complaining that it 
can't open an abstraction within itself.

$ cat .pdrc
-noadc
-lib gridflow

$ pd -verbose -path /usr/local/lib/pd/extra/

Creating a new patch, creating a [@greyscale_to_rgb], and selecting Help 
from the context menu opens the patch instead of opening the help patch.

I think this could be solved by renaming all help patches to X-help, and 
having make install spit out a message saying 'add 
pd/doc/5.reference/gridflow/ to -helppath':
