anchor.diff:  ==== LC20
   _Libraries that are mandatory dependencies of the project's code do not create more restrictions than the Apache License does._
   
  -TODO: do we have a documented verification of that? JIRA ticket? 
  +OK: The list of dependencies at https://wiki.apache.org/incubator/GroovyProposal has been verified when entering incubation.
  +
  +The current dependency licenses (including build, runtime and optional dependencies) are found at
  +https://github.com/apache/incubator-groovy/tree/master/licenses
  +
  +Assembling the licenses depending on the artifacts is done here:
  +https://github.com/apache/incubator-groovy/blob/master/gradle/assemble.gradle
  +so that the various artifacts get their correct sets of licenses.
  +
  +Release reviews have not shown any incompatible licenses.
   
   ==== LC30
   _The libraries mentioned in LC20 are available as Open Source software._

   ==== LC40
   _Committers are bound by an Individual Contributor Agreement (the "Apache iCLA") that defines which code they are allowed to commit and how they need to identify code that is not their own._
  
positive.code: ==== CO10
  _The project has a well-known homepage that points to all the information required to operate according to this maturity model._
  
  http://groovy.apache.org/ redirects to http://groovy-lang.org/ for now. The plan 
  for the future is to use the former for Groovy development topics, and the latter
  for its user community.
  
  
negative.code: that happens.
