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 environment variable and returns the path to the executable. If no program
	   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");
