The main file that you need to hack is the arlad/messages.c, just clean
out everything else. The other file that is intresting that you want
to use is *-subr.c, this file does all conversion from your dir-format
in the smartcard to the OS native format.

The documents are mostly in our heads, the source, some half done pappers
and other places that I have forgot.
If you have any further question I'll happly answer them.
