## Init

```
1. To configure OPAM in the current shell session, you need to run:

    eval `opam config env`

2. To correctly configure OPAM for subsequent use, add the following
line to your profile file (for instance ~/.profile):

    . /root/.opam/opam-init/init.sh > /dev/null 2> /dev/null || true

3. To avoid issues related to non-system installations of `ocamlfind`
add the following lines to ~/.ocamlinit (create it if necessary):

    let () =
        try Topdirs.dir_directory (Sys.getenv "OCAML_TOPLEVEL_PATH")
        with Not_found -> ()
    ;;
```

## opam

```
opam list -a         # List all available packages
opam update          # Update the packages database
opam upgrade         # Bring everything to the latest version possible    

opam switch list --all
opam switch <version> && eval $(opam config env)

opam pin add camlpdf ~/src/camlpdf                            # path
opam pin list

opam install depext
opam depext <packages>
opam list --rec --required-by <package>,<package>... --external

opam switch export file.export  # from the previous switch
opam switch <new switch>
opam switch import file.export
```
