  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.
