man-db is a collection of tools for using the online manuals.  man-db uses
a Berkeley DB database instead of the traditional flat-text whatis
databases. It includes:

  apropos - search the manual page names and descriptions
  catman  - create or update the pre-formatted manual pages
  man     - an interface to the on-line reference manuals
  mandb   - create or update the manual page index caches
  manpath - determine search path for manual pages
  whatis  - search the manual page names
  zsoelim - satisfy .so requests in roff input

This version of the man suite is maintained by Colin Watson.
