-Two programs are currently buildable in this target-utils tree: loadagent and
-pirexplore.  Loadagent is built to be loaded and run out of the Calypso internal
-(on-chip) RAM, and does not depend on any hardware outside of the Calypso chip
-itself - thus it should run unchanged on all Calypso targets.  It expects to be
-loaded by the Calypso ROM bootloader in the UART download mode, and it reads a
-RAM variable left behind by the ROM code that indicates which UART has been used
-to perform that download - it then uses that same UART to communicate with the
-host, presenting an interactive command prompt.  You can run loadagent "raw" by
-loading loadagent.srec with fc-iram, but normally it is used "behind the scenes"
-by fc-loadtool and fc-xram.
+The following target utilities or code components are currently buildable in
+this target-utils tree:
+
+compalstage	For Compal phones only: a little piece of code that is fed to
+		the original fw's bootloader via the serial download protocol
+		provided by the latter; it re-enables the Calypso chip boot ROM
+		and jumps to it, allowing our loadagent to be loaded in the
+		same way as on freedom-enabled devices.
+
+helloapp	Template/skeleton for building programs like loadagent and
+		pirexplore.
 
-Pirexplore is built in the same manner as loadagent (also runs out of IRAM,
-expects to be loaded with fc-iram, and presents an interactive command prompt
-on the autodetected UART), but it automatically performs some hardware (board
-level) initialization specific to the Pirelli, and offers additional commands
-for exploring the hardware features of this device.

+tf-breakin	Here we build the payload for the tfc139 hack-utility; see
