                  (required when executing compiled scripts).
- jawk_src_{rel}.jar - JAR containing the Jawk source code.
- jawk_doc_{rel}.jar - JAR containing the Jawk JavaDoc documentation.

Changes:
Version 1.02:
- ENHANCEMENT: AVM modified to use JRT.
- ENHANCEMENT: Added getSUBSEP to VariableManager.
- ENHANCEMENT: Release of Extension Subsystem for interpreted mode.
  + Addition of _EXTENSION_ intermediate code instruction.
  + Addition of org.jawk.ext to jrt.jar (for future inclusion to compiled mode).
  + Release of Core, Socket, and Stdin extensions.
  + Added broadcast.awk to jawk_ex.{rel}.jar.
  (Note: the opcode is not recognized in compiled mode.)
- ENHANCEMENT: Made [s]printf supporting routines and some other JRT routines static.
- ENHANCEMENT: For interpreted mode, improved operand stack
  checking and error reporting.
- ENHANCEMENT: For interpreted mode, introduced exec() function to
  parse/execute Jawk scripts within a Jawk script.
  + Addition of _EXEC_ intermediate code instruction.
  (Note: the opcode is not recognized in compiled mode.)
- BUG FIX: Not all references to JRT class in AwkCompilerImpl.java
  are referred to by the JRT_Class static class field.
- BUG FIX: In compiled mode, ENVIRON is not populated with
  environment variables.
  + Added envr.awk regression test script.
- BUG FIX: ARGC is off by 1.
  + Added argc.awk regression test script.
- BUG FIX: scalar[key] causes a ClassCastException (should cause
  an AwkRuntimeException).
- BUG FIX: In compiled mode, OFMT, CONVFMT, SUBSEP and OFS cannot be
  integers or doubles.
  + Added vaob.awk regression test script.
- BUG FIX: Jawk throws a semantic exception while parsing "delete ID".
  + Addition of _DELETE_ARRAY_ intermediate code instruction.
  + Added del2.awk regression test script.
- BUG FIX: AwkScript.EXTENSION_DESCRIPTION described as public
  in JavaDocs when actually defined as private.  (Should be public.)
- DEPRECATED: The -c and -f arguments will continue to support
  intermediate file construction/processing.  However, mismatches
  and inconsistencies resulting from changes in intermediate code
  format between releases is now undefined.  That is, Jawk may fail
  to indicate this as a versioning issue when encountered, resulting
  in other types of runtime errors (i.e., NullPointerException).
