Subject: pgp private key / passphrase (How to?)

Dear list,
I'd like to try to recover my private passphrase fpr a pgp-key. I know
most of it but 3 parts of it, which leaves me with abou 217
possibilities. I suppose this would be "easy" for anybody "in the
knowing", however, this is my first time I'm using JtR. As far as I
understand I would have to write some rule for the to-try-passphrase to
add the specifics at a certain placeā€¦ say, the phrase is
> absdXXXXxyz
And I know that XXXX consists of a combination of numbers only, I could
then tell JtR to try the different combinations (I have a txt file
containing all possibilities, created with crunch), right?

The problem is
a) how do I add pgp support to JtR (I have john-1.7.9-jumbo-7 wit OMP
support running) and b) how would I write the personalized rule for to try?

I hope this is not to much to ask for help and thanks in advance,
Demian
