[metapost] ANN: Metappeal 0.1.0

[Nicola]

Metappeal is an extension to Plain MetaPost, providing a lightweight framework 
for consistent development in MetaPost. Metappeal 0.1.0 is the second release of 
this newborn project, bringing you new prominent features:

- classes and templates;
- delegation;
- new basic data structures (bigints, bigstrings);
- much better documentation (which is different from "very good documentation").

in addition to a unit testing framework, other data structures (arrays, records, 
stacks, lists, trees, mboxes, ...) and parametrized code blocks. Nothing 
graphical yet, sorry (getting classes right was hard enough).

Metappeal is available from:

and feedback is welcome.

Happy MetaPost development!
Nicola
