 *
 *  Convert a raw binary file into an unsigned char array, usable from C.
 *  Example:
 *
 *	./Xconv_raw_to_c somefile.raw hello
 *
 *  gives the following output:
 *
 *	unsigned char hello[] = {
 *		35,10,35,32,32,77,97,107,101,102,
 *		105,108,101,32,105,115,32,103,101,110,
 *		101,114,97,116,101,100,32,102,114,111,
 *		109,32,77,97,107,101,102,105,108,101,
 *		46,115,107,101,108,46,32,68,111,110,
 *	...
 *	}
 *
 *  This is useful to include things such as trampoline code, which needs
 *  to be copied to some specific address at runtime, into a kernel image.
