Hand it a package name as an argument, and it'll print out the names
of any packages providing libraries used by binaries in the package
given as an argument that aren't listed as a dependency for that
package. I fed it my complete list of packages, and it turned up some
interesting things - like a package that had a dependency on a newer
version of itself(!).
This is just a QAD hack. It certainly got a lot of rough edges yet.
See also the sysutils/libchk port. It's also great for finding stale
leftover files from e.g. earlier versions of the port that had a
broken pkg-plist, ports that were not updated correctly, etc.
