/*******************************************************************************
* Generates Java, C, or XML source code containing embedded build version
* information.
*
* <p>
* This program creates source code containing constants describing version
* information for another program.  It is intended to be used as part of a
* makefile or batch script file used to combine one or more components into a
* single executable program or library.  When the source code produced by this
* utility is compiled, the resulting executable object file can be combined with
* the other components of the target program or library.
*
* <p>
* The executable object file resulting from the compilation of the source code
* produced by this utility will contain embedded string constants, reflecting
* the version information specified by the command line options when this
* utility was run.  The embedded strings can be displayed using an appropriate
* file searching utility, such as the <tt>what(1)</tt> and <tt>strings(1)</tt>
* programs of Unix.
*
* <p>
* The resulting Java executable <tt>.class</tt> file can also be run as a
* stand-alone program.  If any options are specified on the command line, the
* embedded version information is displayed on the console; if no options are
* specified, an AWT GUI window is displayed containing the version information.
* The GUI can also be invoked if the <tt>.class</tt> file is contained within a
* jar file and the class is named as the <tt>Main-Class</tt> attribute in the
* manifest file of the jar file.
