     11 # For each of a list of patches, invoke separate tools to update
     12 # sources, do a build, and run one or more tests. 
     13 #
     14 # Define these in a file whose name is the argument to this script:
     15 #   REG_IDLIST: List of patch identifiers.
     16 #   REG_UPDATE: Pathname of script to update the source tree.
     17 #   REG_BUILD:  Pathname of script to build enough of the product to run
     18 #               the test.
     19 #   REG_TEST:   Pathname of script to run one or more tests.
     20 # Optional:
     21 #   VERBOSITY:  Default is 0, to print only errors and final message.
     22 #   DATE_IN_MSG If set to anything but 0, include the time and date in
     23 #               messages
     24 #   REG_STOP    Pathname of a file whose existence says to quit; default
     25 #               is STOP in the current directory.
