pkfind – A 'find' command which understands pk files
The TDS standard specifies that pk and gf files contain \special strings to identify the contents of the files. Pkfind is a variant of the GNU find utility modified to understand those specials, and to act on them in some cases. For example, it can be used to delete all pk files created by gsftopk from a subdirectory tree.
