The Nana project was inspired by some other projects, in particular:
Anna is available from:Anna is a language for formally specifying the intended behaviour of Ada programs. It extends Ada with various different kinds of specification constructs from ones as simple as assertions, to as complex as algebraic specifications. A tool set has been implemented at Stanford for Anna, including:
- standard DIANA extension packages, parsers, pretty-printers;
- a semantic checker;
- a specification analyser;
- an annotation transformer; and
- a special debugger that allows program debugging based on formal specifications
All tools have been developed in Ada and are therefore extremely portable. Anna has thus been ported to many platforms. For more information send e-mail to "[email protected]". Before down loading the huge Anna release, you may wish to copy and read some Anna LaTeX reports.

Eiffel is a pure object-oriented language featuring multiple inheritance, polymorphism, static typing and dynamic binding, genericity (constrained and unconstrained), a disciplined exception mechanism, systematic use of assertions to promote programming by contract, and deferred classes for high-level design and analysis.
Nana is essentially a poor mans implementation of some of these ideas which works for C and C++. Ideally in the best of all possible worlds you might want to look at Eiffel or in the military world Ada and Anna. If you use TCL/TK you might also be interested in Jon Cook's `AsserTCL' package.
