Paranoid::Module -- Paranoid Module Loading Routines
=head1 VERSION
$Id: Module.pm,v 0.81 2009/03/05 00:09:34 acorliss Exp $
=head1 SYNOPSIS
use Paranoid::Module;
$rv = loadModule($module, qw(:all));
=head1 DESCRIPTION
This provides a single function that allows you to do dynamic loading of
modules at runtime.
=head1 SUBROUTINES/METHODS
=head2 loadModule
$rv = loadModule($module, qw(:all));
Accepts a module name and an optional list of arguments to
use with the import function. Returns a true or false depending
whether the require was successful. We do not currently
track the return value of the import function.
