#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<scan_for_prereqs> 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<CPAN::Meta::Requirements> object to reflect
#pod its findings about the PPI document.

Perl::PrereqScanner::Scanner - something that scans for prereqs in a Perl document
=head1 VERSION
version 1.100
=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 the L<CPAN::Meta::Requirements> object to reflect
its findings about the PPI document.
=head1 PERL VERSION
This library should run on perls released even a long time ago.  It should work
on any version of perl released in the last five years.
Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.
