+compilation of Rust binaries with @code{musl}.  Inspired by other container
+inits like @url{https://github.com/krallin/tini, tini} and
+@url{https://github.com/Yelp/dumb-init, dumb-init}, catatonit focuses on
+correct signal handling, utilizing @code{signalfd(2)} for improved stability.
+Its main purpose is to support the key usage by @code{docker-init}:
+@code{/dev/init} – <your program>, with minimal additional features planned.")
