gemspec

# This section of the gemspec is for Puppet CI; it will pull in
# a supported beaker library for testing to overwrite the gemspec if
# a corresponding ENV var is found. Currently, the only supported lib
# is beaker-pe, which can be injected into the dependencies when the
# following ENV vars are defined: BEAKER_PE_PR_AUTHOR,
# BEAKER_PE_PR_COMMIT, BEAKER_PE_PR_REPO_URL. These correspond to the
# ghprb variables ghprbPullAuthorLogin, ghprbActualCommit,
# and ghprbAuthorRepoGitUrl respectively. In the "future", we should
# make this a standard format so we can pull in more than predefined
# variables.
