+# 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.
