/*
The restart parameter can be used to rebuily only some of the frameworks.
One can either rebuild alll frameworks where the parameter matches the prefix of a 
framework name, no matter if keyed or non-keyed:
--restartWith angu 
(Matches keyed and non-keyed angular, angularjs, angular-ivy, ...)
Or it can be restrict matching to keyed or non-keyed frameworks:
--restartWith keyed/angu
(Matches only keyed angular, angularjs, angular-ivy, ...)
The distinction is made by checking whether a slash is contained in the parameter

Changed behaviour: Builds only the frameworks. To build webdriver-ts or the results use the npm run install-local task
