Disclosure => i'm participating in the Flaka project

Flaka is an extension for Ant that runs with Ant versions
1.7.x and 1.8.x.
A main project goal of Flaka is the simplification of writing
a build script.

Flaka requires:

Ant >= 1.7.x Java >= 1.5

Flaka provides:

1. An expression language (Java Unified Expression Language) allowing access to data objects, many scripting parts become obsolete
2. Conditional and repetitive control structures like when, unless, while, for, choose, switch ..
3. Exception handling
4. Additional types, tasks and macros
5. A comprehensive documentation
