/* sendOSC.c
Matt Wright, 6/3/97
based on sendOSC.c, which was based on a version by Adrian Freed
Text-based OpenSoundControl client. User can enter messages via command
line arguments or standard input.
Version 0.1: "play" feature
Version 0.2: Message type tags.
pd version branched from http://www.cnmat.berkeley.edu/OpenSoundControl/src/sendOSC/sendOSC.c
-------------
-- added bundle stuff to send. jdl 20020416
-- tweaks for Win32 www.zeggz.com/raf 13-April-2002
-- ost_at_test.at + i22_at_test.at, 2000-2002
modified to compile as pd externel
--20060308 MP clear out some unused code and improve conversion from pd types to OSC types
