+      Specifies values for variables to use when populating the codeparser cache.
+      This can be used selectively to set dummy values for variables to avoid

+      be included are those where the value is not significant for where the
+      codeparser cache is used (i.e. when calculating variable dependencies for

       Specifies the path to a log file into which BitBake's user interface
       writes output during the build.
