# Use this program to fix up files that have the wrong
#  end-of-line character. It will rewrite the file (with the same name)
#  with the fixed up characters.
# Call it like this:
#  python fixupEOL.py <name of broken file>
# where <name of broken file> should be the name of your .csv or .txt file
# for example
#  python fixupEOL.py tree_data.csv
