=head1 NAME
Perl::PrereqScanner::Scanner - something that scans for prereqs in a Perl document
=head1 VERSION
version 0.101890
=head1 DESCRIPTION
This is a role to be composed into classes that will act as scanners plugged
into a Perl::PrereqScanner object.
These classes must provide a C<scan_for_prereqs> method, which will be called
like this:
$scanner->scan_for_prereqs($ppi_doc, $version_requirements);
The scanner should alter alter the L<Version::Requirements> object to reflect
its findings about the PPI document.
