Hi

I wrote a little script I formerly used to start my seti@home clients, and modified to start my BOINC client.

It handles running BOINC as another user, nice'ing the process, starting/stopping, returning the results _really_ immediately (modifying the rpc_min_time field before restarting the client) and stats (I'm using BOINCStats).

I figured it may be useful to other, so here it is.

Enjoy.
