Password Analysis

[Roderick Ford]

I noticed that there was a sort of password analysis running during some "change 
password" procedure, where it was telling the "goodness" of a password on a 
scale.  If I entered a good mix of capitals and numbers and lowercase, of 
course, the "goodness" was best.

My question is whether there is some command-line program that does this 
analysis, or if there is a library, that the GUI (I think it was GTK or Gnome) 
was using.

Thanks,
Rod
