21 # Takes as cmdline parameters two JIRA-formatted benchmark results, as produced
22 # by bm2jira.pl (located in the same directory as this script), and outputs a
23 # third JIRA-formatted comparison table, showing the differences between two
24 # benchmarking runs' java.text and ICU4J columns, after accounting for the
25 # KeywordAnalyzer column; the "ICU4J Improvement" column is ignored.
27 # The difference is calculated as a percentage:
29 # 100 * (patched-rate - unpatched-rate / unpatched-rate)
31 # where the (un)patched-rate is:
33 # 1 / ( elapsed-(un)patched-time - elapsed-KeywordAnalyzer-time)
