Okay. I think that this has been discussed a lot, and decided that it will be
benefitial to a lot of people. Since the compression would most likely be on
the computer, it would be very likely that adding in this BWT later wouldn't be
too hard. I hope whoever is gonna do this eventually will do it soon.
Hmm. Maybe this is a sugestion to add in ZShell 5.0. Make it do the
uncompression automatically, then delete the program. That would be cool.
