Ocamlbuild is no longer recursive by default
From Gallium
In the release 3.10.0 ocamlbuild had the default tag declaration:
true: traverse
Look at the traverse tag for more information about this tag.
The problem with this default setting is that when starting, ocamlbuild wants to read deeply the whole current directory. For instance running ocamlbuild -documentation in your home could take a while.
For this ocamlbuild only recursive when:
- You give it the -r flag.
- You have a _tags or myocamlbuild.ml file in your directory.
