allspice is a collection of java libraries designed to make it easy to
create (or extend) languages that run on top of the JVM.

Major components in more or less top-down order:

javacompiler       A Java 1.0 compiler.
compiler           Utility for creating compilers.
structured         The representation of structured concepts (statements, expressions, etc)
structuredtobc     Converts structured concepts into intermediate byte code
bytecode           The representation of intermediate byte code  (ADD, MUL, PUSH, etc)
bctojvm            Converts intermediate byte code to raw jvm bytecode

Components that are more tool oriented and could
be used for other purposes:

parsergen          A YACC-like tool
parser             A highly generic LALR(1) parser
utilities          A set of useful classes used by other things here.
