#
# This module is used to create signature.h and pgxc_ctl_bash.c files.
#
# pgxc_ctl_bash.c files contains two information,
# 1. Bash script to read pgxc_ctl configuration information and write
# it back to pgxc_ctl. This way, users can use their familiar bash
# script to configure postgres-xc cluster.
# This includes typical (test) configuration so that pgxc_ctl
# can run even with incomplete configuration.
# 2. Template postgres-xc cluster configuration used by pgxc_ctl.
# You can get this template by typing "prepare configu" command.
#
# signature.h contains signature information which is useful in
# checking the bash script and pgxc_ctl binary build.
#
# At present, the bash script is installed each time pgxc_ctl is invoked
# and uninstalled, this has no significant role. In the future,
# when we need to maintain this bash script, it will work to enforce
# the integrity between the two.
