%description
AsmTools helps develop tools to create proper and improper Java '.class' files.
Aids various Java .class based testing and OpenJDK development applications.
Asmtools supports latest class file formats, in lock-step with JDK development.
AsmTools consist of a set of (Java class file) assembler/dis-assemblers:
Jasm/Jdis:
An assembler language to provide Java-like declaration of member signatures,
providing Java VM specification compliant mnemonics for byte-code instructions.
JCod/JDec:
An assembler language to provide byte-code containers of class-file constructs.
