Looks good, thanks. As our CI handles the PyPI deploy we need either a [skip ci] in the commit message or a version bump (it's OK to version bump, no worries about numbers getting too big!)

Hey, @rennerocha ! I can not see the vim temporary files. Is this title still updated?

[cuducos]

@lipemorais The point was not the vim files (this was an extra I guess). The point (descirbed in #128) was the dist/ and build/ ; )

@rennerocha would you mind updating the branch (from master) and adding a patch version bump so we cam merge this?

[rennerocha]

vim files are an extra ... as I use vim, it was bothering me to have its files there :-)
updated the version now
