+            Apache Commons CLI
+                Version 1.4
+               Release Notes
+
+
+INTRODUCTION:
+
+This document contains the release notes for this version of the Commons CLI
+package. Commons CLI provides a simple API for working with the command line
+arguments and options.
+
+Commons CLI 1.4 is a feature release and binary compatible with the
+previous versions, except for the OptionValidator class that is no longer public
+(change introduced in v1.2). Commons CLI 1.4 at least requires Java 5.0.
+
+More information can be found on the project site at
+https://commons.apache.org/cli.
+
+
+NEW FEATURES
+============
+
+o CLI-269: Introduce CommandLine.Builder
+o CLI-267: Add an addRequiredOption method to Options.
+           Thanks to Ricardo Ribeiro.
+
+
+BUG FIXES
+=========
+
+o CLI-265: Optional argument picking up next regular option as its argument.
+           Thanks to Martin Sandiford.
+o CLI-266: HelpFormatter.setOptionComparator(null) doesn't display the values
+           in inserted order. Thanks to Ravi Teja.

+
+
+                Release Notes for version 1.3
+
+NOTES
+=====
+
+A new parser is available: DefaultParser. It combines the features of the
+GnuParser and the PosixParser. It also provides additional features like
+partial matching for the long options, and long options without
+separator (i.e like the JVM memory settings: -Xmx512m). This new parser
+deprecates the previous ones.

+           trigger a ParseException instead of a NullPointerException.
+o CLI-201: Default properties provided as input to the Parser.parse() methods
+           are now correctly processed.
+o CLI-215: CommandLine.getParsedOptionValue() now returns a String object if no
+           option type has been explicitly set. Thanks to Manuel Müller.
+o CLI-212: HelpFormatter now prints command-line options in the same order as
+           they have been added. Thanks to Per Cederberg.
