+# because you don't have that database installed - it is ignored and the 
+# commit continues, perhaps ending successfully. 
+# Databases in this list MUST compile successfully during a commit, or the 
+# entire commit will fail. List the databases your application will actually 
+# be using to ensure your updates to that database work properly.
