/* NOTE: These LDIF2DB and DB2LDIF fn pointers are internal only for now.
   I don't believe you can get these functions from a plug-in and
   then call them without knowing what IFP or VFP0 are.  (These aren't
   declared in slapi-plugin.h.)  More importantly, it's a pretty ugly
   way to get to these functions. (Do we want people to get locked into
   this?)

   The correct way to do this would be to expose these functions as 
   front-end API functions. We can fix this for the next release.
   (No one has the time right now.)
