Neat!  I'll try it out and probably use it as a base for our config
management update system.  Thank you very much and please continue 
working on it and posting updates when you have made significant 
improvements to the previous version.

I added some more functionality to it so it can be used 
better. It even has a minimal help :-)

OK; I'm in the process of adding some additional functionality too.
I tweaked the version you sent over so that it has colorized diffs.
I'll merge in your new additions and post the result sometime tomorrow.
Please continue to enhance your script as you have time.

Best Regards,
