+# Script:  logplot.py
+# Purpose: use GnuPlot to plot two columns from a LAMMPS log file
+# Syntax:  logplot.py log.lammps X Y
+#          log.lammps = LAMMPS log file
+#          X,Y = plot Y versus X where X,Y are thermo keywords
+#          once plot appears, you are in Python interpreter, type C-D to exit
