# ACE Virtual filesystem executive v0.1
# Works with unace v2.5

# Note: There are two packages for Debian: 'unace' (v1.2b) and
# 'unace-nonfree' (v2.x). This script supports 'unace-nonfree' only.
# 'unace', which supports only old versions of ACE archives (and is
# therefore of little use), uses the pipe character to separate columns
# in its listing format.
