SiteName in a plugin? I'm sure it's obvious, but how do I get the current site name from within a plugin?

I tried a few things, including

craft()-&gt;systemSettings-&gt;getSettings('general')


Any ideas?
From searching the files (i.e. 'craft/app/Craft.php' line 124) it looks like you can get it using:

craft()-&gt;getSiteName()
