Synopsis:
   set help_path [<directory>]

Description:
   This variable, if set, contains the path to the top-level help directory
   for ircII-EPIC.  The path may be relative or absolute; absolute is
   recommended.

See Also:
   help(1)

Restrictions:
   Unlike LOAD_PATH, and most other "path" settings, the HELP_PATH may
   only contain a single directory, not a list to search through.
