extended timetag support, including a first attempt at using (get-universal-time)
for timestamping. still not ntp compatible.

Open Sound Control

This is a common-lisp implementation of the Open Sound Control
Protocol, aka OSC. The code should be close to ansi standard, and does
not rely on any external code/ffi/etc+ to do the basic encoding and
decoding of packets. since OSC does not specify a transport layer,
messages can be send using TCP or UDP (or carrier pigeons), however it
seems UDP is more common amongst the programmes that communicate using
the OSC protocol. the osc-examples.lisp file contains a few simple
examples of how to send and recieve OSC via UDP, and so far seems
reasonably compatible with the packets send from/to max-msp, pd,
supercollider and liblo. . .

more details about OSC can be found at . .,
    http://www.cnmat.berkeley.edu/OpenSoundControl/

the current version of this code is avilable using darcs
    darcs get http://fo.am/darcs/osc 

or via asdf-install.. .
         (asdf-install:install :osc)

limitations
  - doesnt send nested bundles or timetags later than 'now' 
  - will raise an exception if the input is malformed
  - doesnt do any pattern matching on addresses
  - sbcl/cmucl/openmcl specific float en/decoding 
  - only supports the type(tag)s specified in the OSC spec

things to do in :osc
  - address patterns using pcre
  - data checking and error handling
  - portable en/decoding of floats -=> ieee754 tests
  - doubles and other defacto typetags
  - correct en/decoding of timetags

things to do in :osc-ex[tensions|tras]
  - liblo like network wrapping 
  - add namespace exploration using cl-zeroconf
