Implies -2a. Negates -f and -8. Use for burning CDs.\n\

\n\
input(s) without a .mon or .dsk extension is assumed to be a binary with a 4\n\
byte header. If the header is missing then you must append ,load_address to\n\
each binary input missing a header, e.g. filename,800. The load address\n\
will be read as hex.\n\
\n\
input(s) with a .mon extension expected input format:\n\
\n\
0280: A2 FF 9A 20 8C 02 20 4F\n\
0288: 03 4C 00 FF 20 9E 02 A9\n\
\n\
A single input with a .dsk extension expected to be a 140K disk image.\n\
\n\
output must have aiff, aif, wav, wave, or mon extention.\n\
\n\
Examples:\n\
\n\
c2t hello hello.mon\n\
c2t -p hello.mon print.mon foo,800 | pbcopy\n\
c2t -2f moon.patrol,801 moon.patrol.aif\n\
c2t -2 hello,300 hello.aiff\n\
c2t -1 hello.mon hello.wav\n\
c2t -2 thief,801 thief.obj,3ffd thief.pic,2000 theif.aif\n\
c2t foo.dsk foo.wav\n\
