+The development of FreeCalypso RF calibration software (sw that requires a
+Rohde&Schwarz CMU200 RF test machine, cannot do anything useful without one,
+and is of any use only to those who engage in *physical production* of Calypso
+hardware devices) was started in the present freecalypso-tools source
+repository, but it is now being moved to a new FC production tools repository.
+The latter repository is currently kept private for business reasons, but it
+WILL be made public hopefully soon, as soon as our present-time business
+complication is resolved one way or another.
+
+When our new FC production tools repository becomes public, all rfcal tools
+will be removed from freecalypso-tools, replaced with a pointer to the new
+public repository containing current versions of these tools; until then, the
+rfcal and doc/RF-cal subdirectories contain the last frozen versions of these
+tools and docs from before the beginning of private development.
