[Fwd: Graphics library for Hugs98?]

[Johan Nordlander]

The latest cvs version of Hugs works with the latest graphics 
library, thanks to some great work by Alastair.  We intend to 
release a new version with precompiled binaries and all in a few 
weeks time.  Everyone is encouraged to check their software 
against the cvs version and report any bugs or incompatibilities.

Point your browser to http://cvs.haskell.org/ for further directions.

All the best,
Johan
