+You may use 'generic' for OS or CPU (useful if your OS or CPU isn't listed).
+
+CPU can be a generic family name or a specific model name. Common aliases are
+supported but not listed. Choosing a specific submodel will usually result in
+code that will not run on earlier versions of that architecture.
