To run OfflineIMAP, you just have to say offlineimap -- it will fire up, ask you for a login password if necessary, synchronize your folders, and exit. See? You can just throw away the rest of this finely-crafted, perfectly-honed manual! Of course, if you want to see how you can make OfflineIMAP FIVE TIMES FASTER FOR JUST $19.95 (err, well, $0), you have to read on!
Gotta love open source manuals :)
