If we're talking about code, then there's KArchive and its subclasses in
kdelibs. You can read and write from/to tar.bz2, tar.gz, .zip and even
.ar in case you need that. Its all in kdelibs/kio, api docs are here:
http://api.kde.org/4.x-api/kdelibs-apidocs/kio/html/classKArchive.html

We're using that in kdevelop for unpacking our project templates from
the .tar.bz or .zip files (depending on the OS thats being used).
