For each prerequisite, the version with which JArgs has been tested is given in parentheses. Any version equal to or later than this should work.

Apache Ant (1.4.1), by The Apache Software Foundation, from Ant is used to build JArgs, and to run its tests.

JUnit (3.7), by Eric Gamma, et al, from JUnit is used to run the unit tests, and is not needed to run the library itself.


To compile, package, and test the code, run


Two jars are created, one called lib/jargs.jar, which contains the runtime library, and one called lib/jargs-test.jar, which contains the unit tests and the examples. The Javadoc APIs are created in doc/api.

To use the library with your own code, simply ensure that lib/jargs.jar is on the CLASSPATH.


The main documentation is the detailed worked example in src/jargs/examples/gnu/, plus the generated API documentation in doc/api/.
