=head1 NAME

minimae - A small, cuddly version of maemian

=head1 PURPOSE

Maemian is the maemo version of lintian - a policy checker designed to
assure the quality of a package uploaded into the maemo.org repositories.
The goal of maemian is to improve quality by checking that the maemo
packaging policy is followed. In order to do that it reads files in the
uploaded deb. Currently maemian only looks at the .dsc file and tries to
ascertain who uploaded it, and if they used the correct email address.

=head1 SYNOPSIS
   
    # Check a debian description file
    minimae -i file.dsc
