[ANNOUNCE] luaffi: call arbitrary C functions from Lua

[luagnome@...]

Hi everyone,

Some time ago, someone if it was possible to call arbitrary C function from the
Lua interpreter without writing wrappers. A kind soul mentionned a library,
called libffi that make this kind of feature possible.

I have wrapped libffi (with luaswig, also use for luagnome/luagtk) and I have
delivered a working snapshot of this developement. 
If you are interested, see <http://luagnome.free.fr/luaffi.php3>.
A short documentation (HOW_TO_USE.html) is included in the downloadable sources.

Feedback welcome!
