Bravo ! The installation is complete.
You can now start to register programs for completion.

To help you in your programming, we advise you to add the following variables to your environment.
>> PYTHONPATH=\$PYTHONPATH:\$HOME/.bash-completer/lib
>> RUBYLIB=\$RUBYLIB:\$HOME/.bash-completer/lib

The bash-completer has been installed in ~/.bash-completer. It's important that you do not move it to another location.
Otherwise, the program will stop to work.

To uninstall this, go to ~/.bash-completer and execute th uninstaller
cd ~/.bash-completer
./uninstall

Up to now, there is no system to update automatically your version of bash-completer.
Just uninstall and reinstall everything if a newer version comes up.

One more note:
You can always review this message by executing ./install --notes
