I just ran dired, put point on the name of a subdirectory, and hit Z
(dired-do-compress), hoping that maybe Emacs would offer to create a
compressed tarball or zip file out of the directory.  Alas, it simply
said "gzip: /private/tmp/rs5rack12.2015-04-19.1109PDT is a directory".

bug#20384: 24.5; feature suggestion: in dired-mode, "Z" on a directory should create a tarball or zip file

[Oleh Krehel]

Thanks, I've installed a change for this in master:

- "Z" on dirname will run "tar -czf dirname.tar.gz dirname"
- "Z" on dirname.tar.gz will run "tar -zxvf dirname"
