JCLAP helps Java developers to create simple-to-use command-line interfaces for their applications. his utility allows you to easily parse all these command-line arguments, retrieve the values assigned, and even semi-automatically display help information about the available arguments. The primary aim is to parse command-line argument in the POSIX standard, which is what most end users will already recognize. In addition JCLAP supports long names for options, and an option to stop argument parsing, in the style of the GNU standard. JCLAP takes this hybrid approach to provide a highly flexible way to specify arguments.
