+# @section DESCRIPTION
+# A script to generate convergence plots from the error norms of an EDGE computation.
+# Identifies error norms in xml files and extracts them for plotting according to the error norm. 
+# The extracted files and the plots will be placed inside a "plots" folder in the same directory as the error directory.
+# MAKE SURE there is no other directory named "plots" in there!
+# The goal is to use display one plot for every error norm and quantity and display the values for gts, lts, parallel and not parallel.
+#
+# Usage ./error_norms_convergence_plots.sh /path/to/error/folder NumberOfQuantities 
+# 
+# @section DEPENDENCIES
+# This file depends on the following projects: 
+# xmlstarlet: http://xmlstar.sourceforge.net/
+# gnuplot: http://www.gnuplot.info/index.html
