+=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*
+ 
+=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.
+

+ 
+=head1 BUGS AND LIMITATIONS
+
+There are no known bugs in this application.
+
+Please report problems to the author.
+
+Patches are welcome.
