[rancid] Question about retaining multiple versions of Cisco configs

[Stephen Novotny]

Hello, 

We are currently on the verge of deploying RANCID as a production 
system.  Is there a way to retain a number of last good configs in the 
../rancid/var/<netname>/configs directory?  Currently it retains a 
single config which I assume is overwritten when a change is observed.  
We would like to retain the last 3 revisions.

Regards
Stephen
