XCrySDen is a crystalline and molecular structure visualisation program aiming
at display of isosurfaces and contours, which can be superimposed on
crystalline structures and interactively rotated and manipulated.
Readme
This app currently just acts as a link to OSC's XDMoD installation and
is currently visible only to OSC staff.
When building the rpm, first change ownership of the directory to group oscstaff and chmod 750.
Hopefully the permissions will then be retained.
