OPAM is a source-based package manager for OCaml. It supports multiple simultaneous compiler installations, flexible package constraints, and a Git-friendly development workflow. Managing your OCaml installation can be as simple as:

opam list            # List the available packages
opam install lwt     # Install LWT
opam update          # Update the package list
...
opam upgrade         # Upgrade the installed packages to their latest version
