Currently there are no restrictions on license names, but obviously |
| 2 |
they cannot be arbitrary. (For example, they cannot end with a |
| 3 |
question mark because that would collide with use-conditionals.) |
| 4 |
|
| 5 |
The patch below restricts their names to the standard |
| 6 |
[A-Za-z0-9_][A-Za-z0-9+_.-]* set of characters. |

|

This agrees with usage in the tree. I could find only one single |
| 9 |
instance of a license with a deviating filename [1], which however was |
| 10 |
removed more than 10 years ago. |
