ffstools	This directory subtree was originally created to hold the source
		for our TIFFS In Vitro Analyzer tool, but has since been
		extended to contain various tools that perform static (or "in
		vitro") transformations on various bits of data that go into
		the flash file system on our FreeCalypso GSM devices or are
		contained in other vendors' flash data structures.

librftab	A library for reading and writing RF parameter tables in our
		FreeCalypso ASCII format - see doc/RF_tables.

libserial	All of our host programs that operate on serial ports (the way
		in which we communicate with GSM device targets) go through
		libserial, i.e., our serial port handling code has been factored
		out into a common library.

loadtools	fc-loadtool, fc-iram, fc-xram and fc-compalram form the part of
		FC host tools called loadtools, which used to be its own
		package.

		fc-buzplay is also built in the loadtools suite because it uses
		many of the same components.

miscutil	A few miscellaneous utilities are built here.

ringtools	Tools for working with ringtone melodies are built here.

rvinterf	Everything dealing with the RVTMUX interface to running GSM
		firmwares and everything based on the rvinterf framework is
		built under rvinterf.

		The tfc139 utility, which logically belongs with loadtools, is
		built in the rvinterf subtree because it is built from mostly
		the same source components as rvtdump and rvinterf.

target-utils	The source for loadagent and compalstage lives here, along with
		a few extra target utilities that are of interest only to
		developers.

toolchain	Scripts and patches for building the gcc+binutils toolchain
		targeting ARM7, the CPU core of the Calypso GSM/GPRS baseband
		processor.  You'll need to build and install this toolchain
		first before you can build target-utils.

uptools		The User Phone Tools suite is built here - see
		doc/User-phone-tools.
