First round of 'complete_command' hook, implements customizable command line ...
r394 """ Tab completion support for a couple of linux package managers
This is also an example of how to write custom completer plugins
or hooks.
Practical use:

[ipython]|2> apt-get u<<< press tab here >>>
update upgrade
