TODO
  ==========
  
  * Convert comments to the Kernel-Doc format.
  
  * Befs_fs.h has gotten big and messy. No reason not to break it up into 
  	smaller peices.
  
  * See if Alexander Viro's option parser made it into the kernel tree. 
  	Use that if we can. (include/linux/parser.h)
  
  * See if we really need separate types for on-disk and in-memory 
  	representations of the superblock and inode.
