+      The Black Magic Probe is a modern, in-application debugging tool
+      for embedded microprocessors. It allows you to see what is going
+      on "inside" an application running on an embedded microprocessor
+      while it executes.
+
+      This package builds the firmware for all supported platforms,
+      placing them in separate directories under the firmware
+      directory.  It also places the FTDI version of the blackmagic
+      executable in the bin directory.
