[turba] Question on sources.php

[Eric]

In sources.php it says:

"This file is where you specify the sources of contacts available to users 
at your installation. It contains a large number of EXAMPLES. Please remove 
or comment out those examples that YOU DON'T NEED."

So, if all I'm using is MySQL for a database, then all I need to keep is 
the block that starts with

$cfgSources['localsql'] = array(  (at about line 113)

... and ends with ...

     'use_shares' => true,
);

at about line 173.

Everything else in that whole file can be blown away.

Right?
