# Important Environment Variables
# ---
# $ghprbActualCommit
#+  This is the hash of the most recent commit in the PR.
#+  The merge-base of this and master is the commit from which the PR was branched.
# $sha1
#+  If the patch merges cleanly, this is a reference to the merge commit hash
#+    (e.g. "origin/pr/2606/merge").
#+  If the patch does not merge cleanly, it is equal to $ghprbActualCommit.
#+  The merge-base of this and master in the case of a clean merge is the most recent commit
#+    against master.
