Cygwin startup and root directory.

Thu Dec 12 06:38:00 GMT 2019

Thank you Corinna!  And sorry for the delayed response.
Maybe this is something I can put on my TODO "wish list" -- going
through the Cygwin docs, learning the internals a bit better and maybe
adding to them.  It's always nice to have a nice doc explaining the
high-level architecture and then other docs to "drill down" to the
details on certain areas.  I've always been amazed by what Cygwin does.
