[Dovecot] Password scheme module thoughts?

Hi, all.

I have successfully deployed the code I wrote to handle Post.Office password hashes. However, I had to implement it as a hack to password-scheme.c. I'd like to implement it as a module so I don't have to hack Dovecot whenever a new release comes out. However, I had a few thoughts:

1. I used Dovecot's own MD5 routines in my implementation because I know how they behave. However, would it make sense to distribute the C sources for the MD5 routines, or would it make far more sense to have a Dovecot build tree already (so I can use Dovecot's function library)?

2. Is there good documentation for Dovecot's plugin API? I need it so I can figure out how to write the parts which the main program call so then the code can be used as a plugin.

Thanks!
