+
+This tool composes a firmware file, out of:
+1. Template for the first Flash page
+2. Bootloader
+3. Archos image
+4. Rockbox image
+
+Use with extreme caution, the components have to match!
+The aspects are:
+- Model (Player, Recorder, FM, V2)
+- boot type (standard boot ROM or ROMless)
+
+Such a firmware file can then be programmed with "firmware_flash.rock".
