elan - 3.1.1-3 main

elan is a small tool for managing your installations of the Lean theorem
prover. It places lean and leanpkg binaries in your PATH that automatically
select and, if necessary, download the Lean version described in the
lean_version field of your project's leanpkg.toml. You can also install,
select, run, and uninstall Lean versions manually using the commands of the
elan executable.
