Could you please fill the issue description with the relevant information of what this is PR for, why, etc.?
Also, could you create an issue?

[evenstensberg]

There's a couple of issues on this already. Read on general improvements tickets and the old PR that was submitted on this. It's work in progress :)

[ematipico]

Yes, I know. But for clarity and transparency we want to fill the whole template to give information to the community. Please fill the template with relevant information

EDIT: typo

[shellscape]

Please be mindful not to wholesale copy elements of structure and/or content from webpack-command. The recent 3ced7e5 commit adds files to 'lib/gorups that exactly match lib/flags in webpack-command.

@evenstensberg The most important CI builds failed. This way your PR can't be merged.

Please take a look at the CI results from travis (failure) and fix these issues.
