# For a package which only configures another, "parent" package.

#   PACKAGE=short-name
#   GEN_FILES=(files to generate)
#   PARENTPACKAGE=(parent-package another-parent-package)
#   . /lib/init/config-init.sh
#   config_init "$1"
#
# PACKAGE       - name to appear in log message
# GEN_FILES     - files to be generated with gen-files.sh
# PARENTPACKAGE - packages to receive start, etc, commands passed through
#
# Global variables GEN_FILES, PARENTPACKAGE may be unset for zero
# values, or scalars for one.  If run under sh, they cannot be arrays.
