NAME
       OpaL::where - Perl extension for locating system resources.

SYNOPSIS
         use OpaL::where qw(which);

DESCRIPTION
       OpaL::where is a module for locating system resources.

FUNCTIONS
       which
           Which takes a program name and searches for that in the PATH envi-
           ronment variable and returns the path to the executable. If no pro-
           gram is found with that name undef is returned instead.

           This is similar to the program with the same name. See which(1).

           USAGE:
               $t = "which"("perl");
