{- TODO

Here we detail our support for the IEEE Std 1003.1-2001 standard.  For
each header file defined by the standard, we categorise its
functionality as

 - "supported" 

   Full equivalent functionality is provided by the specified Haskell
   module.

 - "unsupported" (functionality not provided by a Haskell module)

   The functionality is not currently provided.

 - "to be supported" 

   Currently unsupported, but support is planned for the future.

Exceptions are listed where appropriate.
