Confused about the sub-modules

[Erik de Castro Lopo]

Hi all,

I'm a bit confused about how the GHC dev tree handles submodules like
libraries/Cabal, libraries/process, libraries/directory and
libraries/containers.

All of these libraries/submodules seem to have their own github projects
where people can submit PRs, but once the commits have been made there,
what is the process to get submodules updated in the GHC tree?

Any light people can shed on this process would be appreciated.

Erik
