-   Here is a simple package example. It defines an (optional) attribute
-   <literal>minimumOCamlVersion</literal> that will be used to throw a
-   descriptive evaluation error if building with an older OCaml is attempted.
-   It uses the <literal>fetchFromGitHub</literal> fetcher to get its source.
-   It sets the <literal>doCheck</literal> (optional) attribute to
-   <literal>true</literal> which means that tests will be run with
-   <literal>dune runtest -p angstrom</literal> after the build
-   (<literal>dune build -p angstrom</literal>) is complete.
-   It uses <literal>alcotest</literal> as a build input (because it is needed
-   to run the tests) and <literal>bigstringaf</literal> and
-   <literal>result</literal> as propagated build inputs (thus they will also
-   be available to libraries depending on this library).
-   The library will be installed using the <literal>angstrom.install</literal>
