+ * The API to manipulate the "refs" is currently undergoing a revamp
+   to make it more transactional, with the eventual goal to allow

+ * We no longer attempt to keep track of individual dependencies to

  * In tests, we have been using NOT_{MINGW,CYGWIN} test prerequisites
    long before negated prerequisites e.g. !MINGW were invented.
    The former has been converted to the latter to avoid confusion.
