From man gpg2:

       gpg2 [--homedir dir] [--options file] [options] command [args]

       gpg2  is  the OpenPGP part of the GNU Privacy Guard (GnuPG). It is a tool to provide digital encryption and signing services using the OpenPGP standard. gpg2 features
       complete key management and all bells and whistles you can expect from a decent OpenPGP implementation.
