  28    The idea is that this file will eventually have wrappers around all
  29    important system calls in samba. The aims are:
  30
  31    - to enable easier porting by putting OS dependent stuff in here
  32
  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.
