depfinder finds the dependencies of Slackware packages. The dependency list can be output to stdout, to a .dep text file without version information, or to a slack-required file with version information. depfinder is very fast; its speed is mainly due to the C++ code that is used in depfinder to find in which package each individual library is included.
