like the file says by its name, its the Vidalia Geo IP Cache, in longer
words: its a file where vidalia stores the location of routers and
destinations, because getting the location is expensive, this information is
cached.

those accept and reject lines define the exit policy, look at:
http://www.torproject.org/tor-manual.html.en

there is no flag for a tor server "i'm a exit node", "i'm a middle man", tor
simply fetches for all servers the exit policy and trys to find a node which
allows your kind of service, this node becomes _your_ exit node for this
connection.
