JSAP
JSAP (Java Simple Argument Parser) not only syntactically validates your program's commandline arguments, but it converts those arguments into objects you specify. There's a pretty big (and growing) list of return types suppored by JSAP, including Integers, Floats, Dates, URLs, and even java.awt.Colors; you can also add your own in a matter of minutes. Cascading configuration files can provide arguments not supplied at the command line, and a custom ANT task is included to generate a JSAP class based on your commandline configuration.

Release Notes: A new layout for option help was added to avoid problems with long option descriptions. The SimpleJSAP class was added to speed up common configurations. StringParsers were added. Singletons of most StringParsers were added to avoid unnecessary object creation. Default values for parameters are now indicated in auto-generated help. No-space short options, a la GNU getopt, were added ("-b5" == "-b 5"). A means to determine whether a value was specified by a user or obtained by default was added. Experimental XML support for JSAP configuration was added. Several minor bugfixes and documentation corrections were made.
