Sexplib now available for OCaml 3.10

Archive: http://groups.google.com/group/fa.caml/browse_frm/thread/6d87dd2e32378d45/7357515c6ebe3223#7357515c6ebe3223

Markus Mottl announced:
I am happy to announce that the Sexplib library has been ported to OCaml 3.10: 

 http://ocaml.info/home/ocaml_sources.html#sexplib310 

It now depends on the type-conv library, which factors out common 
functionality for future type conversion libraries (e.g. an upcoming 
type-safe and extremely efficient binary protocol library): 

 http://ocaml.info/home/ocaml_sources.html#type-conv 

Sexplib is also available through Godi, which will automatically 
resolve the dependency on type-conv. 

The new release also comes with several bug fixes, performance 
improvements and small feature extensions. 

Here is a short description of Sexplib (from the README): 

 This library contains functionality for parsing and pretty-printing 
 S-expressions. In addition to that it contains an extremely useful 
 preprocessing module for Camlp4, which can be used to automatically 
 generate code from type definitions for efficiently converting OCaml-values 
 to  S-expressions and vice versa. In combination with the parsing and 
 pretty-printing functionality this frees users from having to write their own 
 I/O-routines for datastructures they define. Possible errors during automatic 
 conversions from S-expressions to OCaml-values are reported in a very 
 human-readable way. Another module in the library allows you to extract and 
 replace sub-expressions in S-expressions.
			

Using folding to read the cwn in vim 6+

Here is a quick trick to help you read this CWN if you are viewing it using vim (version 6 or greater).

:set foldmethod=expr
:set foldexpr=getline(v:lnum)=~'^=\\{78}$'?'<1':1
zM

If you know of a better way, please let me know.
