%description
Visualizing crystal structures and selected area electron diffraction
(SAED) patterns.  It provides functions cry_demo() and dp_demo() to load a
file in 'CIF' (Crystallographic Information Framework) formats and display
crystal structures and electron diffraction patterns.  The function
dp_demo() also performs simple simulation of powder X-ray diffraction
(PXRD) patterns, and the results can be saved to a file in the working
directory.  The package has been tested on several platforms, including
Linux on 'Crostini' with a Core™ m3-8100Y Chromebook, I found that even on
this low-powered platform, the performance was acceptable. T. Hanashima
