JOpt Simple [1] is a Java library for parsing command line options. The JDK has several
different home-grown versions of command line option-parsing code. Where possible,
new and existing tools in the JDK should consider using JOpt Simple. JOpt Simple is
being used in a number of tools in project jigsaw [2].

This issue proposes to integrate JOpt Simple into JDK 9 as a new module that be used,
internally, by tools in the JDK. It is NOT intended to be exported for use outside the JDK.
