Announcing Beam

beam is a file format that makes it easier to write LaTeX beamer. A beam compiler (synonymously implementation) turns a .beam file into a .tex file and invokes latexmk. As of writing one exists in Rust and one for C is planned (partially for greater portability, and partially as an exercise in learning C for my own sake).

I’ll just show you what an example beam document looks like, since the spec is so simple.
