 Its core technologies (Martian, grokcore.component) are also used in other Zope-based projects.The primary motive behind Grok is to make the Zope Toolkit technology more accessible and easier to use for newcomers and, at the same time, speed up application development, in accordance with the agile programming paradigm.To achieve this, Grok uses convention-over-configuration instead of using an explicit XML based configuration language (ZCML) as Zope Toolkit and BlueBream do.
