Help browser doesn't find comport
https://forum.pdpatchrepo.info/topic/12464/query-dsp-state/19 :
Please hammer away at the help browser in Purr Data by adding issues to the tracker: https://git.purrdata.net/jwilkes/purr-data/issues ...
That help browser searches all the external libs that are already installed on your machine, so being able to successfully leverage that should address a lot of the problems.
OK, here's one: Searching for "comport" finds nothing. But...
$ locate comport
/opt/purr-data/lib/pd-l2ork/extra/comport/comport-help.pd
... and I can create a [comport] without adding any additional search/startup paths. The external is there, but the help browser doesn't see it.
