# Test:
#
#  1. Install old verson of Alien::Base
#  2. Build an alien dist (defaults to Acme::Alien::DontPanic out of git)
#  3. test that dist
#  4. Upgrade to current version of Alien::Base
#  5. run test tests again
#
# The defaults check a specific regression that happened between 0.019 and 0.020 where
# the format in ConfigData.pm changed.  I expect this script should be used to verify
# the goodness of any future change to the format of the data in ConfigData.pm in the
# future, but it does require the attention of developers to recognize this danger and
# add the appropriate test to the .travis.yml

# arguments: url git_tag subdir ab_git_old_tag
#
# WHERE
#
#  url - the URL to the Perl module that you want to test (either a .git repo or a .tar.gz file)
#  git_tag - the tag to checkout if using a .git repo
#  subdir - which directory in the git repository or tarball that should change into
#  ab_git_old_tag - the tag to the old version of Alien::Base
