This module generates the configuration data structure for hblink.py and
|
|
assoicated programs that use it. It has been seaparated into a different
|
|
module so as to keep hblink.py easeier to navigate. This file only needs
|
|
updated if the items in the main configuraiton file (usually hblink.cfg)
|
|
change.
