@hswong3i Wrong upstream repo?

[hswong3i]

Sorry I remove the create web/modules web/themes and web/profiles code from script handler, so the test get failed (because I already remove that from my https://github.com/drustack/drustack-standard/blob/master/src/Composer/ScriptHandler.php)

Latest commit try to create those folder manually ;-)

• https://www.drupal.org/node/2755745

I like the original ordering better. This is just alphabetical but it is of little use. I think this better remain with contextual ordering.

[hswong3i]

The reformat is mainly due to running :%!python -m json.tool inside vim ;-)

Some update due to https://www.drupal.org/node/2760467 changes.

Closing this because its a huge change i won't copy the vendor cleanup script and info rewrite. We could create seperate plugins for it.
