The script eplot_lapw plots total energy vs. volume or total energy vs. c/a-ratio using the file case.analysis. The latter should have been created with grepline or the ``Analysis Analyze multiple SCF-files'' menu of WIEN in a BOX and the file names must be generated (or compatible) with ``optimize.job''.
For a description of how to use the script for batch like execution call the script using
eplot_lapw -hend:eplot
begin:dosplot
