centralized management of clientlaunch.cfg

I have a number of custom scripts spread across multiple machines; I
understand how to configure them in clientlaunch.cfg  but I would like
to keep them in a single config file (it's impractical to maintain
this many individual configs). Has anyone written a tool to manage
push/pull of the configs and generating individual hobbit-clients.cfg,
or otherwise duplicate what bb-bbexttab did?
