Distributing binaries and toolchains to developers is a pain but DotSlash makes it a breeze. Instead of committing large, platform-specific executables to your repository, DotSlash combines a fast Rust program with a JSON manifest prefixed with a #! to transparently fetch and execute the binary you need. Tune in to our interview with Andres and Michael to learn more.
