Extensions to L<PPI|PPI>.http://search.cpan.org/dist/PPIx-Utilities/
This is a collection of functions for dealing with PPI objects, many of
which originated in Perl::Critic. They are organized into modules by the
kind of PPI class they relate to, by replacing the "PPI" at the front of
the module name with "PPIx::Utilities", e.g. functionality related to
PPI::Nodes is in PPIx::Utilities::Node.
