Package: hpodder
Version: 0.99.1
Severity: wishlist
Tags: patch
In some circumstances, it's useful or necessary to postprocess
podcasts after downloading them. For instance, my little music player
can play videos too, but only if they're in a very particular format. A
posthook could be used to
The attached patch implements this by adding a "setposthook" command,
which takes the full pathname of a script to execute after downloading a
podcast. The script should take a single argument, the full pathname of
the podcast.
