[tor-talk] Real basic questions for linux

[Praedor]

As it appears that the only tor app being provided by the tor project these days is the tor browser bundle, how is one supposed to simply run tor as a relay or exit or bridge if it is only provided as a browser bundle?

How does one avoid staring multiple tor instances and only start up the browser component?  I close the aurora browser and that leaves tor client running but when I seek to start the browser again later, up comes a NEW tor client instance.
