+=head1 NAME
+
+Crypt::PGP.pm - A wrapper over Network Associates command line PGP tool
+
+=head1 DESCRIPTION
+
+C<Crypt::PGP> is inherited from the abstract base class C<Crypt>, implementing the abstract methods required for PGP encryption, decryption, etc... by calling NAI Inc. PGP command line tool (tested with version 6). For this module to work the PGP executable must have the name C<pgp.exe> and exist in one of the directories defined in the users path.
