| 9 " First of all, MetaPost language don't expect any identation rules. | |
| 10 " This screept need for you only if you (not MetaPost) need to do | |
| 11 " exactly code. If you don't need to use indentation, see | |
| 12 " :help filetype-indent-off | |

| 14 " Note: Every rules of identation in MetaPost or TeX languages (and in some | |
| 15 " other of course) is very subjective. I can release only my vision of this | |
