The hkl library is a framework for diffraction computation and diffractometer control, heavily used at the soleil synchrotron. it supports various types of diffractometer geometry: eulerian 4-circle, eulerian 6-circle, kappa 4-circle, kappa 6-circle, and z-axis geometry. for each of these it provides several numerically computed modes, such as bisector and constant psi.

this package provides the runtime hkl library.
