2 * codec.conf parser
3 * by Szabolcs Berecz <szabi@inf.elte.hu>
4 * (C) 2001
6 * to compile test application:
7 * cc -I. -DTESTING -o codec-cfg-test codec-cfg.c mp_msg.o osdep/getch2.o -ltermcap
8 * to compile CODECS2HTML:
9 * gcc -DCODECS2HTML -o codecs2html codec-cfg.c mp_msg.o
11 * TODO: implement informat in CODECS2HTML too
