# ABSTRACT: something that scans for prereqs in a Perl document

use Moo::Role;

#pod =head1 DESCRIPTION
#pod
#pod This is a role to be composed into classes that will act as scanners plugged
#pod into a Perl::PrereqScanner object.
#pod
#pod These classes must provide a C method, which will be called
#pod like this:
#pod
#pod   $scanner->scan_for_prereqs($ppi_doc, $version_requirements);
#pod
#pod The scanner should alter the L object to reflect
#pod its findings about the PPI document.
#pod
#pod =cut

requires 'scan_for_prereqs';

# DO NOT RELY ON THIS EXISTING OUTSIDE OF CORE!
# THIS MIGHT GO AWAY WITHOUT NOTICE!
