 =head1 DESCRIPTION
 
-tpm is a tiny shell script which is heavily inspired by pass(1) and uses
-gpg2(1) to securely store your passwords. Invoking tpm consists of
-specifying a command, either I<insert> or I<show>, and supplying one
-entry as a target. If I<insert> is specified as a command tpm will
-create a new entry and read the corresponding password from STDIN. If
-you specify I<show> as a command tpm will print the password of the
-corresponding entry to STDOUT.
