The group definitions must come **after** the panel definitions. A good way
to go is to put all the group definitions at the very end of the geometry file.
-If the detector consists of only one panel, CrystFEL will automatically create
-the **all** group containing it.
+If you do not define any groups, CrystFEL will automatically create the **all**

The **group** system replaces the **rigid_group** system used in older versions
of CrystFEL. If the geometry file contains any **rigid_group** lines, they
