| // The Alpha package is for checkers that have too many false positives to be |
| // turned on by default. The hierarchy under Alpha should be organized in the |
| // hierarchy checkers would have had if they were truly at the top level. |
| // (For example, a Cocoa-specific checker that is alpha should be in |
| // alpha.osx.cocoa). |

| // The OptIn package is for checkers that are not alpha and that would normally |
| // be on by default but where the driver does not have enough information to |
| // determine when they are applicable. For example, localizability checkers fit |
| // this criterion because the driver cannot determine whether a project is |
| // localized or not -- this is best determined at the IDE or build-system level. |
| // |
| // The checker hierarchy under OptIn should mirror that in Alpha: checkers |
| // should be organized as if they were at the top level. |
| // |
| // Note: OptIn is *not* intended for checkers that are too noisy to be on by |
| // default. Such checkers belong in the alpha package. |
