SCRATCH
directory where case.vector and case.help?? are stored. For parallel execution this directory must be available from all remote machines!

if set will pop up instead of an editor with case.struct during init_lapw
XCRYSDEN_TOPDIR
if this variable is set will activate all interface extensions to XCrysDen.

WIEN_GRANULARITY
Default granularity for parallel execution. It is overridden by setting the granularity in the .machines file or in $WIENROOT/parallel_options

if set the residual k-points are spread one by one over the processors.
