spin out the file system

[plastikfan]

I'm toying with the idea of spinning out the file system package into it's own package, called nefilim.. It would have to be strictly self contained, that means it could not use any other snivilised project. This would allow li18ngo to use nefilim. This also means it couldnt be created using the astrolib template.

The other repo I had the idea of creating to provide afero adapters for traverse could now be called nefero; a poartmanteau of nefilim and afero.
