2# This is a modified copy of version.pm 0.9909, bundled exclusively for
3# use by ExtUtils::Makemaker and its dependencies to bootstrap when
4# version.pm is not available.  It should not be used by ordinary modules.
5#
6# When loaded, it will try to load version.pm.  If that fails, it will load
7# ExtUtils::MakeMaker::version::vpp and alias various *version functions
8# to functions in that module.  It will also override UNIVERSAL::VERSION.
