Version 0.5
    * Feature-for-feature reimplementation in C with a small XS layer
    * Remove option of "GNU extensions"; GNU extensions are now always available
      and use is implied
    * Slightly better adherence to POSIX ustar header format, such as with ustar
      header magic
Version 0.4
    Resolve an issue of build-time modules in mk/ being picked up by
    CPAN's indexer, resulting in an "UNAUTHORIZED RELEASE" warning, by declaring
    the PMLIBDIRS value in Makefile.PL to include only 'lib', and using a trick
    (thanks RURBAN!) to cause the PAUSE indexer to not pick up the package
    declarations in the files in mk/
