/**
 * TextDump provides a full description of the data structures in a Flash file.
 * 
 * The tool reads the Flash file and writes the names of the data structures
 * along with the fields and values decoded to a specified file. The output is
 * formatted with tab-stops to show the depth of the decoded data structures and
 * values.
 * 
 * The tool takes two arguments:
 * 
 * --fileIn <flashfile> the name of a Flash (.swf) file.
 * 
 * --fileOut <textfile> the name of the file where the text description will be 
 *                      saved.
