-=head1 NAME
-
-ard-reset-arduino - Reset an Arduino
-
-=head1 USAGE
-
-    $ ard-reset-arduino /dev/cu.usb*
-
-    $ ard-reset-arduino --verbose --period=0.1 /dev/cu.usb*
-
-    $ ard-reset-arduino --verbose --caterina /dev/ttyUSB0
-
-=head1 DESCRIPTION
-
-To reset (most) Arduinos, it's enough to just pulse the DTR line.
-
-You can do that from the shell with stty, but there's an interesting
-diversity of command flags. This little program gives a uniform interface
-at the cost of requiring C<Device::SerialPort>.
-
-=head1 OPTIONS
-
-=over
-
-=item --verbose
-
-Watch what's going on on STDERR.
-
-=item --period=0.25
-
-Specify the DTR pulse width in seconds.
-
-=item --caterina
-
-Reset a Leonardo, Micro, Robot or LilyPadUSB.
-
-=back
-
-=head1 BUGS AND LIMITATIONS
-
-There are no known bugs in this application.
-
-Please report problems to the author.
-
-Patches are welcome.
-
-=head1 AUTHOR
-
-Martin Oldfield, ex-atelier@mjo.tc
-
-Support for Leonardo/Micro added by sej7278, https://github.com/sej7278
-
-Thanks to Daniele Vergini who suggested this to me, and supplied
-a command line version.
