JSON 
====

Parser **program** is generated as C99 code by default.
However, you can generate it as JSON.  You can convert the JSON program
to C program using a function call.  A library is provided utility file for this.

    	static int ReadFile(const char * filename, char ** text, unsigned int * length)

		*text = malloc(length[0] + 1);
		memset(*text, 0, length[0] + 1);
		fread(*text, 1, length[0], fp);
		fclose(fp);
		return 1;
