#
# @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


echo "Hi, I am starting now!"

# remove and make new files
# $1 is /path/to/error/folder
# $2 is NumberOfQuantities

rm -r -f $1/plots
mkdir $1/plots

# find relevant data and extract into different files
