library for structural biology - executable

 Library for macromolecular crystallography and structural bioinformatics. For
 working with coordinate files (mmCIF, PDB, mmJSON), refinement restraints
 (monomer library), electron density maps (CCP4), and crystallographic
 reflection data (MTZ, SF-mmCIF). It understands crystallographic symmetries,
 it knows how to switch between the real and reciprocal space and it can do a
 few other things.
 .
 This package contains main gemmi executable.
