mtz2sca and mtz2hkl: facilitated transition from CCP4 to the SHELX program suite

Two programs are presented that facilitate the transition to refining macromolecular data with the SHELX suite. mtz2sca is used to convert data processed and integrated with MOSFLM into sca format for further processing with SHELXC and SHELXD; mtz2hkl is used to convert an mtz file used for refinement in REFMAC5 into or format for refinement with SHELXL or SHELXH.
