Two graphical frontends have been written for slapt-get, the backwards-compatible dependency-tracking extension to Slackware's package tools used by VectorLinux. VL-APT was the first, written originally by the Vector developers to serve the need for GUI package installation and management, while gslapt was written by the original developers of slapt-get for the same purpose. Until recently, either option has been viable; however, recent changes in the slapt-get packaging format have made VL-APT obsolete, and the developers of Vector have consequently promoted gslapt as the preferred method of graphical package management.
