# This CMake script finds the BAZAAR version control system executable and

# and fetches the veresion string to valid that BAZAAR was found and executes

# properly.

#

# Usage:

#  find_package( BAZAAR )

#

# 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.

#
