## 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
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.ferro.pro/dev/ocaml.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
