# This reads out some metadata about the current running version of Barkeep from files written at deploy time.
# In particular, git information such as the current HEAD, current branch, and user info are written to
# "git_deploy_info.txt", and all the commits reachable from HEAD (that is, the set of all commits contained in the
# deploy) are written to "all_commits.txt".
# This information is exposed through the /statusz route.
