+%description
+Vala is a programming language using modern high level abstractions without
+imposing additional runtime requirements and without using a different ABI
+compared to applications and libraries written in C. Vala uses the GObject
+type system and has additional code generation routines that make targeting
+the GNOME stack simple. Vala has many other uses where native binaries are
+required.
