# Version management helpers. These functions help to set, save and load the
# following variables:
#
# OPENIM_GIT_COMMIT - The git commit id corresponding to this
# source code.
# OPENIM_GIT_TREE_STATE - "clean" indicates no changes since the git commit id
# "dirty" indicates source code changes after the git commit id
# "archive" indicates the tree was produced by 'git archive'
# OPENIM_GIT_VERSION - "vX.Y" used to indicate the last release version.
# OPENIM_GIT_MAJOR - The major part of the version
# OPENIM_GIT_MINOR - The minor component of the version
# Grovels through git to set a set of env variables.
#
# If OPENIM_GIT_VERSION_FILE, this function will load from that file instead of
# querying git.
