# compare.shingle.benchmark.jira.tables.pl
#
# Takes as cmdline parameters two JIRA-formatted benchmark results, as produced
# by shingle.bm2jira.pl (located in the same directory as this script), and
# outputs a third JIRA-formatted comparison table.
#
# The difference is calculated as a percentage:
#
# 100 * (unpatched-elapsed - patched-elapsed / patched-elapsed)
#
# where (un)patched-elapsed values have had the no-shingle-filter
# (StandardAnalyzer) elapsed time subtracted from them.
