You can use it from the command line, from a built in CLI shell or from a GUI (that resembles Synaptic somewhat but actually seems better in a few ways I found right off the top). It's actually supposed to work better than the other tools (apt/yum/etc) in that occassionally there will be problems that those resolvers can't handle. Smart is supposed to be able to resolve dependency issues where the others can't, and supposedly you can even mix repos that will cause major disasters if mixed using the other tools.

Mind you I've only played with this for a couple of hours now, but I am rapidly becoming a fan. Have fun!
