This program does very little on its own. It is intended to be used as a module
to build applications on top of the HomeBrew Repeater Protocol. By itself, it
will only act as a peer or master for the systems specified in its configuration
file (usually freedmr.cfg). It is ALWAYS best practice to ensure that this program
works stand-alone before troubleshooting any applications that use it. It has
sufficient logging to be used standalone as a troubleshooting application.

'''
This program does very little on its own. It is intended to be used as a module
to build applications on top of the HomeBrew Repeater Protocol. By itself, it
will only act as a peer or master for the systems specified in its configuration
file (usually freedmr.cfg). It is ALWAYS best practice to ensure that this program
works stand-alone before troubleshooting any applications that use it. It has
sufficient logging to be used standalone as a troubleshooting application.
