Uh... I'm checking stuff in. Jeremy will by *so* pleased :)
netatalk.c contains the meat of the code required to move Macintosh resource forks around when Windows users manipulate files created by a mac. This allows for greater integration between netatalk and Samba, but is, of course, potentially a recipe for disaster. All the netatalk related code is insulated by #ifdefs from the standard build. (This used to be commit 05a5243d841cecd128e29379eab2a2784262ccc7)
