+# Pi = has satnogs-client, rotator controller, SDR, etc.
+# Workstation = Your local workstation.
+#
+# Set up the Pi to use soapyremote.
+# On Pi, stop satnogs-client and start soapyremote.
+# On workstation, run CubicSDR and connect remotely
+# to "soapyremote" device (not rtlsdr) and the IP address of the Pi.
+#
+# This script needs CubicSDR running, as it takes screenshots from it.
+# Yes, this is very crufty. :)
+# Then it moves the rotator, lets things settle, takes another shot,
+# rinse, repeat.
+#
+# Reqires gnome-screenshot.
+#
+# So run this script on your worklstation, then make CubicSDR
+# the main active window # on the workstation, and let the script run.
+#
+# You will also want ssh key access set up from workstation to Pi.
+# The script sends commands using rotctl via ssh...
