database.pl is where the settings to connect to your database can be found. If you change your database settings by hand you will need to edit this file to reflect those changes. Broadly speaking this file will never change.
Example
$c->{dbname} = 'trunk4'; $c->{dbhost} = 'localhost'; $c->{dbport} = undef; $c->{dbsock} = undef; $c->{dbuser} = 'trunk4'; $c->{dbpass} = 'SNsvkvEQ';
