 //
-// This functionality is implemented by the lib/BytecodeWriter library.
-// This library is used to write VM bytecode files to an iostream.  First, you
-// have to make a BytecodeStream object, which you can then put a class into
-// by using operator <<.
-//
-// This library uses the Analysis library to figure out offsets for
-// variables in the method tables...
-//
-// Note that performance of this library is not as crucial as performance of the
-// bytecode reader (which is to be used in JIT type applications), so we have
-// designed the bytecode format to support quick reading.
