#============================================================
# Author: John Theofanopoulos
# A simple parser. Takes the output files generated during the build process and
# extracts information relating to the tests.
#
# Notes:
# To capture an output file under VS builds use the following:
# devenv [build instructions] > Output.txt & type Output.txt
#
# To capture an output file under GCC/Linux builds use the following:
# make | tee Output.txt
#
# To use this parser use the following command
# ruby parseOutput.rb [options] [file]
# options: -xml : produce a JUnit compatible XML file
# file : file to scan for results
#============================================================
