pylint is not used since bb5b1a0. The pyflakes cleanup mentioned in that
commit has not been done, but given that this project is no longer being
actively developed I don't think it's worth spending time doing it.
Leaving the pylint suppressions causes confusion because it leads people
to think that we are still using pylint.

Repo is a tool built on top of Git. Repo helps manage many Git repositories,
does the uploads to revision control systems, and automates parts of the
development workflow. Repo is not meant to replace Git, only to make it
easier to work with Git. The repo command is an executable Python script
that you can put anywhere in your path.
