Yes, that is the one.

Did you source the environment-setup script? If so, what distro were you using?

We were thinking it wouldn't be so granular Basically it would end up matching 
everything in a manifest rather than asking for one particular package. So it 
would look more like "devtool publish-sdk location", followed by users being 
able to then update to whatever "sdk's" exist at that location.
