   4 # ACE Virtual filesystem executive v0.1
   5 # Works with unace v2.5
   6
   7 # Note: There are two packages for Debian: 'unace' (v1.2b) and
   8 # 'unace-nonfree' (v2.x). This script supports 'unace-nonfree' only.
   9 # 'unace', which supports only old versions of ACE archives (and is
  10 # therefore of little use), uses the pipe character to separate columns
  11 # in its listing format.
