/** @file ccp4_spg.h
*
* @brief Data structure for symmetry information.
*
* A data structure for spacegroup information and related
* quantities. Some items are loaded from syminfo.lib while
* others are calculated on the fly.
*
* There is also a struct for symop rotation matrices and translation
* vectors. This can be converted to other representations using
* functions in ccp4_parser.
