# User definable.
# BAZAAR_EXECUTABLE Set this to use a version of BAZAAR that is not in
# current path. Defaults to bzr.

# Defines:
# BAZAAR_FOUND Set to TRUE if BAZAAR command line client is found
# and the bzr --version command executes properly.
# BAZAAR_VERSION Result of the bzr --version command.
