+=head1 EXPLINATION
+
+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 LedgerSMB will operate.

+=head1 LICENSE
+
+Distributed under the terms of the LedgerSMB code.
