I believe Ryan Davis' ParseTree code has an ABC metric example.

Also, Kwala has a number of other options in addition to also being a
front-end to Saikuro.  For example, there is a hook for checking code
duplication using PMD's CPD.  Plus there is code to analyse your
require structure, which can act as a poor man's coupling, but
certainly writing specific coupling metrics would be interesting.  To
be honest I am hoping other people with help out in adding any missing
and useful metrics to Kwala.  Or at least, I hope you get some good
responses so I can find some time to hook them into Kwala ;-)

Cheers,
