event.dispatch
---
A group of applications supporting distributed event handling and retention.
It capitalizes on OTP for hot deployment, communication, and process management.

To build
----
Currently the build file is simple, supporting build and clean targets.
To build:

$ make

To clean:

$ make clean

To run
----
After running make to build the modules, Create to erlang nodes, one named foo:

$ erl -sname foo

and the other bar:

$ erl -sname bar

You may at this time need to edit the client_node.app file and add the
appropriate hostname (see the prompt in the foo node for the correct hostname).
It's currently set to foo@fawkes (the second argument is the name of the
event queue gen_event manages).

Now, in the bar node, load and run the application:

(bar@fawkes)1> application:load(client_node).

Then start it:

(bar@fawkes)2> application:start(client_node).

You'll see some debug printed to the screen.  Now, load the event descriptor
record (you'll need this to send an event):

(bar@fawkes)3> rr("event_descriptor.hrl").

Now back at the foo node, start the command server:

(foo@fawkes)1> command_server:start().

Back at the bar node, send and event:

(bar@fawkes)4> gen_event:notify(event_manager, #event_descriptor{originating_host=bar@fawkes, id=1, message="frankly"}).

Back at foo, you should see something like this indicating the event was
received:

command_server delegating event...{event_descriptor,bar@fawkes,1,
                                      {1283,653263,12500},
                                      low,low,informational,"frankly"}
command_handler handling event: {event_descriptor,bar@fawkes,1,
                                    {1283,653263,12500},
                                    low,low,informational,"frankly"}

At this point you've demonstrated communication between the client node and the
command node (though the command server is currently admittedly a shim module).

Some of these commands are recorded in the scratch file for reuse.  Feel free
to add to this file if needed, but don't delete.
