 # Time in Saudi Arabia and other countries in the Arabian peninsula was not
-# standardized until relatively recently; we don't know when, and possibly it
+# standardized until 1968 or so; we don't know exactly when, and possibly it
 # has never been made official.  Richard P Hunt, in "Islam city yielding to
 # modern times", New York Times (1961-04-09), p 20, wrote that only airlines
 # observed standard time, and that people in Jeddah mostly observed quasi-solar
 # time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
 # o'clock for "Arab" time).
 #
+# Timekeeping differed depending on who you were and which part of Saudi
+# Arabia you were in.  In 1969, Elias Antar wrote that although a common
+# practice had been to set one's watch to 12:00 (i.e., midnight) at sunset -
+# which meant that the time on one side of a mountain could differ greatly from
+# the time on the other side - many foreigners set their watches to 6pm
+# instead, while airlines instead used UTC +03 (except in Dhahran, where they
+# used UTC +04), Aramco used UTC +03 with DST, and the Trans-Arabian Pipe Line
+# Company used Aramco time in eastern Saudi Arabia and airline time in western.
+# (The American Military Aid Advisory Group used plain UTC.)  Antar writes,
+# "A man named Higgins, so the story goes, used to run a local power
+# station. One day, the whole thing became too much for Higgins and he
+# assembled his staff and laid down the law. 'I've had enough of this,' he
+# shrieked. 'It is now 12 o'clock Higgins Time, and from now on this station is
+# going to run on Higgins Time.' And so, until last year, it did."  See:
+# Antar E. Dinner at When? Saudi Aramco World, 1969 March/April. 2-3.
+# http://archive.aramcoworld.com/issue/196902/dinner.at.when.htm

+ * The class reads J2DBench scores and reports them into output stream in format applicable for TeamCity charts.
+ * The directory, where J2DBench result files placed, is specified via command line parameter like follows:
+ * <p>
+ * <code>-basexml | -b <xml file path></code>
+ * </p>
+ * This directory must contain one file with pattern <code>*{openjdk}*.{res}</code> which is considered as a container
+ * of reference scores and several <code>*{jbsdk}*.{res}</code>.
+ * <p>
+ * <p> Names of these files have several mandatory fields separated by <code>"_"</code> and look like
+ * <code>osName_jdkName_renderName_*.res</code>
+ * </p>
+ * <p>
+ * If any of score is less than corresponding reference value by 5% then exit code <code>1</code> is returned otherwise
+ * exit code <code>0</code> is returned.
+ * <p>
+ * Standard output will contain scores in format required for TeamCity charts.
