Need help to batch create pfm files via pf2afm

[NoOp]

I've a large amount of licensed postscript fonts that I'd like to use in
OpenOffice/LO. I have both the .pfb and .pfm files in the same folder
and can generate the .afm file via:

$ pf2afm <fontfilename>

Unfortunately that will get old real fast with 400 font files. How would
I go about using pf2afm to batch convert all 400 in one go?

Note: Abiword only needs the .pfb, but OOo/LO require the .afm.
