MissileManager.
The problem MissileManager tries to solve is to provide a unified high level API
for communicating with missile launchers. While the hardware and functions are
similar, the protocol to control the missile launcers (like moving around, fire 
missile) varies a lot.

Using.
MissileManager is a system daemon and is not meant to be used directly from
the command line. However, since it provides DBus API, it is possible to use
'dbus-send' command to control it from the terminal. There's an example
program (tests/missile-test.py) that demonstrates the basic API usage.

Implementation.
MissileManager is a DBus system bus activated service (meaning it's started 
automatically when a request arrives). It is written in C. The devices are
queried from udev and automatically updated based on hardware events.

API.
The API is open for changes, so if you're writing a plugin and need to add or
change some public method, feel free to suggest it!
