Ppi::xs provides xs-based acceleration of the core ppi packages. it selectively replaces a (small but growing) number of methods throughout ppi with identical but much faster c versions.

once installed, it will be auto-detected and loaded in by ppi completely transparently. the integration between the primary (perl) implementation and the xs-accelerated version are designed to degrade gracefully if they fall out of sync -- the perl version is preferred over the xs version.
