// This file is the main sketch for the Command Station.

// CONFIGURATION:
// Configuration is normally performed by editing a file called config.h.
// This file is NOT shipped with the code so that if you pull a later version
// of the code, your configuration will not be overwritten.
//
// If you used the automatic installer program, config.h will have been created automatically.
//
// To obtain a starting copy of config.h please copy the file config.example.h which is
// shipped with the code and may be updated as new features are added.
//
// If config.h is not found, config.example.h will be used with all defaults.
