/*
  jcf-dump is a program to print out the contents of class files.
  Usage:  jcf-dump [FLAGS] CLASS
  Each CLASS is either:
  + the name of a class in the CLASSPATH (e.g "java.lang.String"), or
  + the name of a class *file* (e.g. "/home/me/work/package/Foo.class").
  + The name of a .zip or .jar file (which prints all the classes in the
  archive).

  OPTIONS:
  -c
	Dis-assemble each method.
  -classpath PATH
	Overrides $CLASSPATH.
  --print-main
	Print nothing if there is no valid "main" method;
	otherwise, print only the class name.
  --javap
	Print output in the style of Sun's javap program.  VERY UNFINISHED.
