# Given a machine-optimal patch makeup table (see ctfcvtptbl), this program
# will allow the build process to determine the following:
#
#   * The patch ID associated with a given module
#   * The KU required by the patch associated with a given module
#   * The patch ID and location of the genunix module preceding the genunix
#     module currently being built.
