      33             :    - to allow for hooks into other "pseudo-filesystems"
      34             : 
      35             :    - to allow easier integration of things like the japanese extensions
      36             : 
      37             :    - to support the philosophy of Samba to expose the features of
      38             :      the OS within the SMB model. In general whatever file/printer/variable
      39             :      expansions/etc make sense to the OS should be acceptable to Samba.
