|   Coq libraries should be installed in <literal>$(out)/lib/coq/${coq.coq-version}/user-contrib/</literal>. Such directories are automatically added to the <literal>$COQPATH</literal> environment variable by the hook defined in the Coq derivation.

|   Some extensions (plugins) might require OCaml and sometimes other OCaml packages. The <literal>coq.ocamlPackages</literal> attribute can be used to depend on the same package set Coq was built against.

 | |
|   Coq libraries may be compatible with some specific versions of Coq only. The <literal>compatibleCoqVersions</literal> attribute is used to precisely select those versions of Coq that are compatible with this derivation.

 | |
|   Here is a simple package example. It is a pure Coq library, thus it depends on Coq. It builds on the Mathematical Components library, thus it also takes <literal>mathcomp</literal> as <literal>buildInputs</literal>. Its <literal>Makefile</literal> has been generated using <literal>coq_makefile</literal> so we only have to set the <literal>$COQLIB</literal> variable at install time.
