XBian tvheadend package

[Mark2013]

I have a working XBian and have ssh'd into the OS successfully.

I want to setup Live TV. In the past (RaspBMC and OpenELEC), I have used tvheadend.

Questions:

Does xbian support tvheadend?

Is it in-built? -Do I get an xbmc add-on of it?

If it is in the xbian repos, does it get installed with or with-OUT "sudo"? Or if it is an add-on is that installed as "root" or as "user"?

If you know a URL that shows how to install packages/apps/etc for XBian, SiliconDust's HDHomeRun (dual ATSC) tuner and Schedules Direct may I ask you to point me towards it? I have netsearched (I don't use Google as a verb) and cannot find XBian specific help.

I have XBian up & running for about 50 minutes at this point in time.
