/* ansitar -- archiver for ansi-format labelled tapes
 *
 * ansitar [crxtvbl] [blocksize] [labelsize] file ...
 *
 * The options are similar to tar:
 *	c - create a tape
 *	r - replace (update) a tape
 *	x - extract files
 *	t - print table of contents
 *	v - set verbose mode: for crx, print names; for t print labels
 *	0-9 - select drive 0-9
 *	b - use next argument as a block size
 *	B - use next argument as tape block size, and
 *		following argument as line size (for blocking/unblocking)
 *	l - use next arg as a label size
 *	U - select upper(out)/lower(in) case translation of names
 *	R - use RT11 label and name conventions (UGH!)
 *	S - use RSTS conventions (==RT11 except 80-byte labels)
 *
 * Warning: The routines skipfile and backspace use nonstandard
 * ioctl calls!
