/**
 * \section tls
 *
 * tls -- Trivial recursive ls, for comparing two directories after
 * running an rsync.
 *
 * The problem with using the system's own ls is that some features
 * have little quirks that make directories look different when for
 * our purposes they're the same -- for example, the BSD braindamage
 * about setting the mode on symlinks based on your current umask.
 *
 * There are some restrictions compared to regular ls: all the names
 * on the command line must be directories rather than files; you
 * can't give wildcards either.
 *
 * At the moment we don't sort the output, but all the files have full
 * names, so you can run it through sort(1).
 *
 * We need to recurse downwards and show all the interesting
 * information and no more.
 *
 * \todo Use readdir64 if available?
