+=head1 EXPLANATION
 
-This util is useful for package builders to identify all the CPAN dependencies we've made.  It required Module::CoreList (which is core, but is not yet in any stable
-release of perl)  to determine if a module is distributed with perl or not.  The output reports which version of perl the module is in.  If it reports 0.000000, then the
-module is not in core perl, and needs to be installed before Lx-Office will operate.
