Hi,
If you can write an ASDL definition for the .sdf tree, asdlGen will
generate read/write code for you in Haskell (or SML/Java/C/C++).
Look at http://www.cs.princeton.edu/zephyr/ASDL/ if you don't know
about ASDL or asdlGen.
HTH.

Hi Keith,
I can point you to one written in ML. It comes with MLRISC.

It's in the library subdirectory. The whole thing is ~600kb. If you

papers are:
"Early Experience with ASDL in lcc", Software-Practice and Experience,
to appear.
"A Machine-Independent Debugger-Revisited", Microsoft Research TR 99-4
both available at http://www.research.microsoft.com/~drh/
> If anyone is interested in any of these facilities, drop us an email.
Do keep the mailing list informed of your progress!

ouple of mirror sites of Haskell.org would also be a good
idea.
