/**
|
|
* \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.
|
|
*
|
|
* We need to recurse downwards and show all the interesting
|
|
* information and no more.
|
|
*
|
|
* \todo Use readdir64 if available?
|
|
*
|
|
* \todo Sort directory entries. Either that, or output file listing
|
|
* in such a format that we can just pipe the whole lot through sort.
