	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	* There are some restrictions compared to regular ls: all the names
	31	* on the command line must be directories rather than files; you
	32	* can't give wildcards either.
	33	*
	34	* We need to recurse downwards and show all the interesting
	35	* information and no more.
	36	*
	37	* \todo Use readdir64 if available?
	38	*
	39	* \todo Sort directory entries. Either that, or output file listing
	40	* in such a format that we can just pipe the whole lot through sort.
