NAME
   Vcdiff::Xdelta3 - Xdelta3 backend for Vcdiff

SYNOPSIS
       use Vcdiff::Xdelta3;

       my $delta = Vcdiff::Xdelta3::diff($source, $target);

       my $target2 = Vcdiff::Xdelta3::patch($source, $delta);

       ## $target2 eq $target

   This module is a backend to the Vcdiff module and isn't usually used
   directly.

DESCRIPTION
   Xdelta3 is a delta encoding library by Joshua MacDonald. The Xdelta3
   source code is embedded into this module and built as a shared object.
   The "xdelta3" command-line binary is not built.

PROS
   *   Doesn't have arbitrary size limitations on source, target, or delta
       files.

   *   Has a really neat feature that lets you merge VCDIFF deltas into a
       single delta. Unfortunately this module doesn't expose that yet.

CONS
   *   GPL licensed

   *   Build system is really weird. I didn't bother figuring out how to
       run Xdelta3's test-suite when installing the CPAN module which is
       unfortunate. Note that installing this module does still run the
       shared test-suite in Vcdiff.
