     dnetc is a distributed computing client that coordinates with servers
     operated by to cooperate with other network-connected
     computers to work on a common task.  It communicates over public networks
     and processes work assigned by the keyservers. It is
     designed to run in idle time so as to not impact the normal operation of
     the computer.


     Since you are already reading this, I assume you know how to unpack an
     archive into a directory of your choice. :)

     Now, simply fire up the client...

     If you have never run the client before, it will initiate the menu-driven
     configuration. Save and quit when done, the configuration file will be
     saved in the same directory as the client. Now, simply restart the
     client. From that point on it will use the saved configuration.

     The configuration options are fairly self-explanatory and can be run at
     any time by starting the client with the ’-config’ option. A list of
     command line options is listed below.


     In addition to the conventional command line passed to the client from a
     shell, options may also be passed to the client using either or both of
     the following methods:
     -    using the dnetc_opt= environment variable.
          If set, this is parsed before the normal command line.
     -    using the /usr/local/etc/dnetc.opt and/or /etc/dnetc.opt
          command files. If found, these are parsed after the normal
          command line.
     "Mode commands" (see below) cannot be executed using these methods, and
     there is no run-time display of modified settings (unless the settings
     are also modified using the conventional command line, in which case the
     last effective change is displayed).

   Mode commands: (the client will execute the option and then exit)
     -config     start the configuration menu

     -flush      flush all output buffers

     -fetch      fill all input buffers

     -update     fetch + flush
