22 * tls -- Trivial recursive ls, for comparing two directories after
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.
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.
34 * We need to recurse downwards and show all the interesting
35 * information and no more.
37 * \todo Use readdir64 if available?
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.
