Preprocessing tool: detector2nexus
==================================

Convert a complex detector definition (multiple modules, possibly in 3D) into
a single NeXus detector definition together with the mask (and much more in
the future)


Purpose
-------

Convert a detector to NeXus detector definition for pyFAI.

Usage:
------

detector2nexus [options] [options] -o nxs.h5
