RANCID is enough :)

A quick expect hack;

Put the following into a file (f.ex. your-script-file.tcl)
expect "#"
send "conf term\n"
expect "(config)#"
send "no logging host 1.1.1.1\n"
expect "(config)#"
send "logging host 2.2.2.2\n"
expect "(config)#"
send "ntp server 2.2.2.2\n"
expect "(config)#"
send "end\n"
expect "#"
send "copy running-config startup-config\n"
expect "#"

And run it on your hosts like;

clogin -s your-script-file.tcl 10.0.0.1 10.0.0.2 10.0.0.3 10.0.0.4 etc. etc.

You can put all the "intelligence" you want into the script, checking for something and acting upon it or not.
