Missing README.md

[qrilka]

@ElvishJerricco you have moved package into subfolder but README.md stays in repo root and yet it's listed in servant-router/servant-router.cabal as extra-source-files.
I guess it's better be fixed.
BTW what was the motivation of that move?

Example warning from stack:

Warning: File listed in .stack-work/downloaded/kiJN60liVunn/servant-router/servant-router.cabal file does not exist: README.md

I should probably just put a README in that directory that points at the GitHub, since that's the only way you'll see the examples.

The move was because I wanted to distinguish the library package from the examples and from the Nix setup. Having the library be the root would have meant polluting it with all these other files. Pure cosmetic.
