urpm::signature - Package signature routines for urpmi
=head1 SYNOPSIS
=head1 DESCRIPTION
=over
=item check($urpm, $sources_install, $sources, %options)
Checks a package signature, return a list of error messages
Options:
=over
=item * basename
whether to show full file paths or only file names in messages (used by rpmdrake)
=item * callback
A callback called on package verification (used by rpmdrake in order to update its progressbar)
