+4.3.28, and supports all commands (in some extent ;)).
+
+
+Installation
+============
+

+
+    $ . /path/to/this/repo/VBoxManage
+
+or add it to a proper place depending on your distribution. Ususal place would

+* /usr/local/etc/bash-completion.d/
+* /etc/bash_completion.d/
+* etc.
+
+It's also okay to copy it into some directory, and place proper line in
