whichman is a "which" alike search command for man pages.
whichman searches the
MANPATH environment variable.
Unlike "which" this program does not stop on the first match. The name
should probably have been something like whereman as this is not a
"which" at all. whichman shows all man-pages that match and allows you
to identify the different sections to which the pages belong.
whichman can handle international manpage path names for different languages.
Man pages in different languages may be stored in .../man/<country_code>/man[1-9]/...
whichman does fault tolerant approximate string matching. With a default tolerance level
(strlen(searchpattern) - number of wildcards)/6 + 1
