	20	* \section tls
	21	*
	22	* tls -- Trivial recursive ls, for comparing two directories after
	23	* running an rsync.
	24	*
	25	* The problem with using the system's own ls is that some features
	26	* have little quirks that make directories look different when for
	27	* our purposes they're the same -- for example, the BSD braindamage
	28	* about setting the mode on symlinks based on your current umask.
	29	*
	30	* All the filenames must be given on the command line -- tls does not
	31	* even read directories, let alone recurse. The typical usage is
	32	* "find\|sort\|xargs tls".
	33	*
	34	* The format is not exactly the same as any particular Unix ls(1).
	35	*
	36	* A key requirement for this program is that the output be "very
	37	* reproducible." So we mask away information that can accidentally
	38	* change.
