Package: zgv
Version: 5.9-2+b1
Severity: wishlist
Below is an adaptation of the fimgs script, zgs, to use zgv in compliment
of fim/fbi to view pdf, ps etc., allowing use of unique zgv features such
as generation/viewing/selection via thumbnails.
The script is not perfect right now, could use a bit of cleanup,
but is usable. Thanks for any feedback/consideration.

# (c) 2010 Dallas Legan
# This is a modified version of the original fimgs script,by Michele Matone
# and is capable of displaying pdf, eps, ps, and dvi files.
# Now enhanced for viewing .cbr and .cbz files :)!
#
# Note : it won't probably work on bash, version < 3.0 because of regular
expressions.
# this script wants a temporary directory to stores rendered/wget'ed files
# this directory is named after the process ID
