This is an updated version of Simon Marlow's original
Haskell Web Server.

The original program is described in:
Developing a high-performance web server in Concurrent Haskell,
Simon Marlow, 
Journal of Functional Programming, 12(4+5):359--374, July 2002
http://www.haskell.org/~simonmar/papers/web-server-jfp.pdf

This version is based on the one available from:
http://cvs.haskell.org/cgi-bin/cvsweb.cgi/fptools/hws/

The following changes have been made:
- Use the hierarchical libraries.
- Use Data.Map instead of FiniteMap.
- Use Parsec from the hierarchical libraries and removed
  the included old parsec copy.
- Removed ifdefs for compatibility with GHC 4.x and 5.x 
  (they wouldn't work with the new imports anyway).
- Use IOUArray in Response.squirt
- Use Cabal for the build system.
