/**
\page services Background Services
The librobotcontrol package sets up two systemd services which the user can enable/disable at will.
Older BeagleBoard images have these services installed but disabled by default. Enable manually like any systemd service or with `sudo dpkg-reconfigure librobotcontrol`.
\section services_s1 rc_battery_monitor service
This service runs in the background and illuminates the 4 battery monitor LEDs on the Robotics Cape and BeagleBone Blue based on the state of a 2-cell lithium battery connected to the white balance connector, or a 3 or 4 cell pack connected to the DC input jack.
If you wish to control those LEDs manually through the [LED module](group___l_e_d.html), then please disable this service first to avoid conflicts.
\section services_s2 robotcontrol service
This service does some preliminary startup checks on boot to ensure the hardware is configured correctly. A short log file of this process is written to /var/log/robotcontrol/startup_log.txt on boot.
After completing the startup checks, this service will then start any program the user as elected to run automatically on boot. If the user's startup program has a problem, closes, or doesn't exist then the librobotcontrol service will show up as failed when calling `systemctl status robotcontrol`. This allows the user to treat their own robot control program like a systemd service, starting and stopping it with `systemctl`. See the <a href="runonboot.html">run on boot page</a> for how to configure this startup program.
