       pwhich - Perl-only 'which'

         $ pwhich perl
         $ pwhich -a perl          # print all matches
         $ pwhich perl perldoc ... # look for multiple programs
         $ pwhich -a perl perldoc ...

       'pwhich' is a command-line utility program for finding paths to other programs based on the user's "PATH". It
       is similar to the usualy Unix tool 'which', and tries to emulate its functionality, but is written purely in
       Perl (uses the module "File::Which"), so is portable.

   Calling syntax
         $ pwhich [-a] [-v] programname [programname ...]

       -a  The option -a will make "pwhich" print all matches found in the "PATH" variable instead of just the first
           one. Each match is printed on a separate line.

       -v  Prints version (of "File::Which") and copyright notice and exits.

       Originated in modperl-2.0/lib/Apache/ Changed for use in DocSet (for the mod_perl site) and
       Win32-awareness by me, with slight modifications by Stas Bekman, then extracted to create "File::Which".

       Version 0.04 had some significant platform-related changes, taken from the Perl Power Tools `which'
       implementation by Abigail with enhancements from Peter Prymmer. See
       <>; for more information.
