# Ensure a certain valac version is available
#
# The initial argument is the version to check for
#
# It may be followed by a optional parameter to specifiy a version range. The
# following options are valid:
#
# EXACT
# Vala needs to be available in the exact version given
#
# MINIMUM
# The provided version is the minimum version. Therefore Vala needs to be
# available in the given version or any higher version
#
# MAXIMUM
# The provided version is the maximum. Therefore Vala needs to be available
# in the given version or any version older than this
#
# If no option is specified the version will be treated as a minimal version.
