JGit is a lightweight, pure Java library implementing the Git version control system, providing repository access routines, support for network protocols, and core version control algorithms.

JOpt Simple is a Java library for parsing command line options, such as those you might pass to an invocation of javac. In the interest of striving for simplicity, as closely as possible JOpt Simple attempts to honor the command line option syntaxes of POSIX getopt and GNU getopt_long. It also aims to make option parser configuration and retrieval of options and their arguments simple and expressive, without being overly clever.

Parallel Java (PJ) is an API and middleware for parallel programming in 100% Java on shared memory multiprocessor (SMP) parallel computers, cluster parallel computers, and hybrid SMP cluster parallel computers.

This package provides a parser for command line arguments.
