|
Merely mentioning the existence of export regulations, without making |
237 |
|
them a condition of the license itself, is acceptable since it does |
238 |
|
not restrict users. If an export regulation is actually trivial for |
239 |
|
free software, then requiring it as a condition is not an actual |
240 |
|
problem; however, it is a potential problem, since a later change in |
241 |
|
export law could make the requirement nontrivial and thus render the |
242 |
|
software nonfree. |
