KEYWORDS="~amd64"
IUSE="+7za +rar unzip"

# Sabnzbd is installed to /usr/share/ as upstream makes it clear they should not
# be in python's sitedir.  See:  http://wiki.sabnzbd.org/unix-packaging

# TODO:  still bundled but not in portage:
# kronos, rsslib, ssmtplib, listquote, json-py, msgfmt, happyeyeballs
# pynewsleecher
#
# dev-python/rarfile is bundled as of 2.0.1 because sabnzbd is modifying it
# https://github.com/sabnzbd/sabnzbd/commit/de6d642b0dc6eaed63199a99d9a1a8b2e3d0018b
#
# Also note that cherrypy is still bundled.  It's near impossible to find
# out where the bundled and heavily patched version came from (pulled from
# cherrypy subversion, patched somewhere, then imported to sabnzbd and patched
# further.  Upstream is planning on making this easier with 0.8.0.
