[Gllug] unzip - slightly off topic

[Zverina, David]

A superior replacement for pkzip is info-zip. It's OSS, 32-bit and fully
cross-platform so it works on *nix, windows, vms, MS-DOG and just about
anything else you could think of. For scripting type use I cannot really
recommend it highly enough.

Cheers,

Dave.
