Hi, List
     Fan <http://www.seas.upenn.edu/~hongboz/hongbo_zhang_files/fan_doc/> ,
a* type-directed generic programming framework for OCaml*
Using Fan, a programmer can easily create generic libraries
for type-directed
programs, including pretty printing, equality, serialization and
deserialization, data generation, generic traversals, folds, etc.

Compared with deriving <http://code.google.com/p/deriving/>, Fan is mainly
different in such aspects:
1. It generate code *without touching your source tree*, module is
the basic unit. We generated code* fo**r all modules in ocaml's compiler*
*parsing/, typing/, and bootstrapped camlp4 source tree itself*.
Check here http://www.seas.upenn.edu/~hongboz/hongbo_zhang_files/fan_doc/
All modules beginning with Fan_ocaml is generated code for ocaml compiler
Fan_camlp4ast_o is for camlp4ast itself.
2. composable.  All extended syntax are in our mini dsl language "fan"
without polluting the original syntax
3. Lightweight   Check the modules
gen_plugins<http://www.seas.upenn.edu/~hongboz/hongbo_zhang_files/fan_doc/code_Gen_plugins.html>
we write generic printing, equality, map, fold traversal, etc,* 9 generic
plugins in less than 200 lines of code*.

It's still at alpha stage, and I have some ideas that need to be polished, *I
would be happy **to hear any feedback.* We hope that FAN can benefit ocaml
community* as a camlp4 platform.* Fan's code base is pretty small, all the
Ast Transformations are based on quasi-quotations. The only exception is
TyDcl which has no counter-part and Ast Lifting, since *the current camlp4
does not support  macro syntax in **common lisp something like ``(,,).*
*

*Many Thanks*
