SBT is run similarly to Ant or Maven via a series of commands that you add on the end of the command line:
$ sbt clean
[info] Loading global plugins from /Users/Sean/.sbt/plugins
[info] Set current project to default-66315d (in build file:/Users/Sean/test/)
[success] Total time: 0 s, completed Feb 15, 2012 12:24:21 PM
SBT also supports being run interactively if no commands are specified:
$ sbt
[info] Loading global plugins from /Users/Sean/.sbt/plugins
[info] Set current project to default-66315d (in build file:/Users/Sean/test/)
> clean
[success] Total time: 0 s, completed Feb 15, 2012 12:25:07 PM
