[j-nsp] Performing a junos-style diff offline

[Phil Mayers]

Does anyone know of a tool or code to do this? I'm writing some 
Junoscript to maintain the security config on our SRX from a database, 
and would like to be able to compare pairs of devices which should, 
after the updates, be identical but may end up with slight unmanaged 
differences.

Getting it in junos-style, rather than plain old diff, would allow the 
differences to be resolved by operator intervention and "load patch".

Alternatively, is there a Junoscript RPC which can be used to diff 
against a remote URL? I don't want to have to load the "other" config 
via <load-configuration> as some of these are (very) large, and that's 
relatively slow.
