Maintaining LJ
--------------

- Lightweight_Java_Definition.thy

Since "Lightweight_Java_Definition.thy" is generated by Ott, it should _not_
be modified directly. Please either:

1) E-mail the main author (rok@strnisa.com) to sort out any problem; or,

2) Modify the provided Ott-source files to obtain the desired result. Please
   notify the main author (rok@strnisa.com) of any such changes.


- Lightweight_Java_Equivalence.thy and Lightweight_Java_Proof.thy

These two files can be modified at will, as long as the semantics of "progress"
and "wf_preservation" is preserved.
