# This is a modified copy of version.pm 0.9909, bundled exclusively for
# use by ExtUtils::Makemaker and its dependencies to bootstrap when
# version.pm is not available.  It should not be used by ordinary modules.
#
# When loaded, it will try to load version.pm.  If that fails, it will load
# ExtUtils::MakeMaker::version::vpp and alias various *version functions
# to functions in that module.  It will also override UNIVERSAL::VERSION.
