# How to invoke:
#  jobs_runtime.R <tsvfile> <testname>
# This script takes in input a TSV file with the following header:
# workload        runtime     build_number
# It generates a png where x is the build number, y is the runtime
# and each workload is a different line. The test name is used to generate
# the output file's name.
# R needs to be installed with the graphic libraries
