XDL VIEW, an X-windows-based toolkit for crystallographic and other applications

The XDL_VIEW toolkit is designed to provide a simple means of including X-windows-based functions into existing programs and to provide the basis for developing new programs. Its use does not require any detailed knowledge of X-windows and it is designed, in particular, to meet the needs of the Fortran programmer. Many of the functions provided are of general purpose but some functions designed for crystallographic programs are included. The current applications of the package are mainly in the field of protein crystallography.
