# Bugs, TODO:
#
#  o Added beep upon success. Take it out if you don't like it. - Raphael
#
#  o .pkg support is premature! It only works if the .pkg
#    is bzip'd, not with gzip'd .pkg's such as Slackware has. - Raphael
#
#  o Needs to pass options (like -v) to called programs
#
#  o STDIN support
#
#  o Need to add a which statement with decompressor missing error
#
#  o I added some support without actually having
#    it, so some more testing is needed
