Some people seem gaga over this kind of file tree representation, but my own file sub-trees that I run file listings on are almost never small enough for the idea to be very helpful. Anyway, with a high profile README feature list bullet, it makes sense to release soon after.

That's the only change, though.

Also a few documentation clean-ups for the probably still impenetrable README.

That's about it; Bump minor to 0.21 though really this code base is pretty stable at this point.

That's about it (plus some README tweaks.)

See changelog for details.

Fix incorrect hyperlink path with absolute files.

This is really only a release to update documentation.

Might work better on OpenBSD or other less popular Unices (if it works at all).

No longer error out even though default "." may be unreadable.

Also some documentation changes & dep updates.
