1491 Matt Wright, 6/3/97
1492 based on sendOSC.c, which was based on a version by Adrian Freed
1493
1494 Text-based OpenSoundControl client. User can enter messages via command
1495 line arguments or standard input.
1496
1497 Version 0.1: "play" feature
1498 Version 0.2: Message type tags.
1499
1500 pd version branched from http://www.cnmat.berkeley.edu/OpenSoundControl/src/sendOSC/sendOSC.c
1501 -------------
1502 -- added bundle stuff to send. jdl 20020416
1503 -- tweaks for Win32 www.zeggz.com/raf 13-April-2002
1504 -- ost_at_test.at + i22_at_test.at, 2000-2002
1505 modified to compile as pd externel
