We, the module installer developers, hereby decree...
Too official? Ok, I'll go again.
In this repository you'll find metadata for projects and modules. It's nice to have that in a central place, apart from any specific module installer (cough proto neutro pls cough), for at least these three reasons:
The set of people who want access to a module installer and the set of people who want access to module metadata are two different sets.
If each installer has one set of metadata, that's more for everyone to keep updated. If it's in a central place, there's less work.
The list of projects in the ecosystem is really an orthogonal to the installer, or even an installer. It might be used for other things, such as rendering the list at http://modules.perl6.org
To add a new module to the ecosystem, add the URL of the module's META.info file to the META.list file here in the ecosystem.
So there you go. It probably bears repeating that all of this is quite temporary; something to sustain us until we can hook up with CPAN goodness in some more long-term way.
Have a nice day.
