| 28 For the time being this module is intended to be called as a script. | |
| 29 However it is possible to import it into an IDE and use the function | |
| 30 check() described below. | |

| 32 Warning: The API provided by this module is likely to change in future | |
| 33 releases; such changes may not be backward compatible. | |

| 35 This is a modified version to make the original tabnanny better suitable | |
| 36 for being called from within the eric6 IDE. | |
