"To remove a subrepo from the parent repo, you must delete the subrepo
definition from the '.hgsub' file at the top level of the parent repo.
Once you do this, the subrepo tree will show up as a set of unknown
files when you run hg status, and you can delete the files."

What problems and warnings do you get?
