Considering the file strucutre below of main module and its submodules,
now it is possible to generate documentation for them main and all its
submodules in one execution, with `--recursive` flag.
Note that generating documentation recursively is allowed only with
`--output-file` set.
Path to find submodules can be configured with `--recursive-path`
(defaults to `modules`).
Each submodule can also have their own `.terraform-docs.yml` confi file,
to override configuration from root module.

In v0.10.0 flags '--no-XXX' have been deprecated in favor of their
counterparts in the format of '--X=false' (e.g. --no-header and
--header=false). And they are completely being removed now (two releases
after original announcement)
