Users of [dune] 3.5 or later can use the [cmdliner install

tool-support] command described above, along with the

[install]} stanza, to hook into the existing [dune build @install] command.

226

For an executable named [mytool] defined in a [dune] file, you can add
227
+
the following to the same [dune] file to populate the completion
228
+
scripts and manpages when running [dune build @install] (which is what
229
+
is used by [opam install]):
230
+
231
+
{@dune[
232
+
(rule
233
+
(target (dir cmdliner-support))
234

236

(ignore-stdout
237

(run cmdliner install tool-support ./mytool.exe:mytool cmdliner-support))))

If these features of dune are not available to your project, you may
245

instead need to update the [opam] file, see {{!tip_tool_support_with_opam_dune}
246

these instructions}.
