%description
WABT (we pronounce it "wabbit") is a suite of tools for WebAssembly. These tools
are intended for use in (or for development of) toolchains or other systems that
want to manipulate WebAssembly files. Unlike the WebAssembly spec interpreter
(which is written to be as simple, declarative and "speccy" as possible), they
are written in C/C++ and designed for easier integration into other systems.
Unlike Binaryen these tools do not aim to provide an optimization platform or a
higher-level compiler target; instead they aim for full fidelity and compliance
with the spec (e.g. 1:1 round-trips with no changes to instructions).
