+Simple build system.
+
+* Purely functional
+* Runs commands in isolated environments (virtual machine or `chroot` or `proot` with `env -i`)
+* Inputs are distinguished at the syntactic level, and dependencies are automatically computed
+* Does not rely on filesystem timestamps
+* Results are memoized (if an output happens to be the same after regeneration, it will not be seen as an updated dependency)
