-update            fetch + flush
-benchmark [prj]   16-20 sec speed check [optional: only project prj]
-benchmark2 [prj]  half (8-10 sec) and slightly inaccurate -benchmark
-bench [prj [cn]]  -benchmark all cores [optional: only project prj]
                   [optional: only core cn, must be used with prj]
-test [prj [cn]]   tests for core errors [optional: only project prj]
                   [optional: only core cn, must be used with prj]

-restart           restart all active clients
-shutdown          gracefully shut down all active clients
-pause             pause all active clients
-unpause           unpause all active clients
-install           install the client in the StartupItems folder
-uninstall         remove the client from the StartupItems folder

Project and buffer related options:

-ini <filename>    override default name of INI file

-nodisk            don't use disk buffer files
-n <count>         packets to complete. -1 forces exit when buffer is empty.
-runbuffers        set -n == -1 (exit when buffers are empty)
-frequent          frequently check if buffers need topping-up
-inbase <fname>    input buffer basename (ie without 'extension'/suffix)
-outbase <fname>   output buffer basename (ie without 'extension'/suffix)
-ckpoint <fname>   set the name of the checkpoint file
-blsize [prj] <n>  set preferred packet size (2^n keys/packet)
-bin <prj> <n>     set fetch buffer threshold to <n> work units
-btime [prj] <n>   set fetch time threshold to <n> hours
                   If not specified, project name <prj> defaults to RC5

Network update related options:

-runoffline        disable network access
-runonline         enable network access
-nettimeout <secs> set the network timeout. Use -1 to force blocking mode
-a <address>       keyserver name or IP address
-p <port>          keyserver port number
-nofallback        don't fallback to a distributed.net keyserver

-ha <address>      http/socks proxy name or IP address
-hp <port>         http/socks proxy port

Performance related options:

-c [prj] <n>       core number (run -config for a list of valid core numbers)
                   project name "prj" defaults to RC5
-numcpu <n>        run <n> threads/run on <n> cpus. 0 forces single-threading.
-priority <0-9>    scheduling priority from 0 (lowest/idle) to 9 (normal/user)

Logging options:

-l <filename>      name of the log file
