\subsection{UB Matrix Calculation for Four Circle Diffractometers}
This module helps in the calculation of UB matrices for four
circle diffraction. This is only an interpreter interface, the
actual functionality is in the ubfour.h, .c files. These are documented
in ubfour.h in order to be able to give this away separatly as a
library.
