+This test demonstrates a bug when there's a package with a meta template and a
+custom version:

+  $ git init -q
+  $ touch foo
+  $ git add .
+  $ git commit -qm _
+  $ git tag -a 1.0 -m 1.0

+  $ cat >foobarlib.ml <<EOF
+  > let foo () =
+  >   print_endline "foobarlib"
+  > EOF
+
+  $ cat >dune <<EOF
+  > (library

+  (lang dune <version>)
+  (use_meta)
