Probably the most granularity you can get is by listening for the snmp 
traps when you get out of configuration mode and pull down the config 
when you see the trap, and push it into an RCS/CVS file.

I can't remember the snmp line you have to put in the config, and I'm 
not even sure what the trap is, but if you experiment a little, it 
shouldn't be too difficult to figure out.

I've never actually used this in practice, but I have thought about it 
- I think you may have issues if you do something like this:

conf t
CTRL-Z
[short space of time]
conf t
CTRL-Z

So you may need a timer/lock file to make sure you don't try to grab 
the config from a router at the same time as another instance of your 
script.

Best regards,
