Vala is a programming language that aims to bring modern programming
language features to GNOME developers without imposing any additional
runtime requirements and without using a different ABI compared to
applications and libraries written in C.

valac, the Vala compiler, is a self-hosting compiler that translates
Vala source code into C source and header files. It uses the GObject
type system to create classes and interfaces declared in the Vala source
code.

This package contains the 0.24 release.
