* Creates a JAR file containing the runtime bits required to run app clients

*
* The resulting file will contain:
*
* - the stand-alone ACC JAR file (the one containing this class)
*
- all JARs listed in the Class-Path of this JAR's manifest
*
- the contents of the ${installDir}/lib/dtds and schemas directories (for
* local resolution of schemas and DTDs on the remote client system)
*
- the specified sun-acc.xml file (the one from domains/domain1/config if unspecified)
*
- the handful of other config files to which sun-acc.xml refers
*
*
* Optional command-line options:
*
* -output path-to-output-file (default: ${installDir}/lib/appclient/appclient.jar)
* -xml path-to-sun-acc.xml-config-file (default: ${installDir}/domains/domain1/config/sun-acc.xml)
