将rft格式文件转换成html格式文件

/* Think C program to make header files for Macintosh. 								*/
/* This program produces rtf.h and stdcharnames.h files for the DuBois RTF parser.	*/
/* The output files have been checked with the Compare Files command of BBEdit and	*/
/* are identical to those produced by awk and sed under UNIX.						*/

/* Input files "standard-names" and "rtf.h.dist" are expected to be in the			*/
/* the directory rtftohtml/Libs/h relative to where the program runs -CJH-		*/
/* Macintosh users may want to use a utility like FileTyper to set the output files	*/
/* creator to 'KAHL' for convenient Mac access.										*/
