+$FreeBSD$
+
+This is a simple example of the firmware(9) system. It consists of two
+parts:
+
+1) fwimage
+ This is the firmware image (the ascii art of beastie from the boot
+ menu). The Makefile lists the firmware file "firmware.img" and the
+ short handle for this firmware image "beastie".
+ Note that the module is called "beastie" as well so that it can be
+ loaded automatically if requested.
+
+2) fwconsumer
+ This module tries to get the a firmware image called "beastie",
+ checks if the data is '\0'-terminated and prints it to the console.
+ It keeps a reference to the firmware until it is unloaded.
+
+This is mainly to demonstrate how to construct firmware image modules.
