The first package on SlackPack for the recently relased Slackware 13.0 is SWareT. The main reason for its realase are the new package formats (tbz, tlz and txz), introduced with the latest Slackware relase. I've patched the original SWareT 1.6.3 release to enable support for these new formats and update the Bulgarian localization.
Enjoy using this excelent tool!
