opam

Opam is a source-based package manager for OCaml. It supports multiple simultaneous compiler installations, flexible package constraints, and a Git-friendly development workflow. Opam was created and is maintained by OCamlPro. To get started, checkout the Install and Usage guides. Run ./configure. If you don't have the dependencies installed, this will locally take care of all OCaml dependencies for you (downloading them, unless you used the inclusive archive we provide for each release). This is all you need for installing and using opam, but if you want to use the opam-lib (to work on opam-related tools), you need to link it to installed libraries. It's easier to already have a working opam installation in this case, so you can do it as a second step. If you install on your system (without changing the prefix), you will need to install as root (sudo). As sudo do not propagate environment variables, there wil be some errors.
