# contents of VERSION is used.

# usage:
# getversion.sh <keyword> [sha]
# keywords:
# release
# describe the version of the latest release.
# Marked by tags of this form: vX.Y[.Z]
# prerelease
# describe the version of the latest prerelease.
# Marked by tags of this form: vX.Y[.Z]-rc[C]
# snapshot
# describe the version of the current HEAD commit.
# build
# describe the version of the currently checked out
# commit; used as the version in the cmc binary.
#
# If the second parameter to the script is the string 'sha',
# getversion.sh will display the sha1 checksum of the commit
# in question rather than a human readable name.
