| # 04_gnu_licenses |
| |
| This example shows how to deal with the GNU style licenses such as GPL, AGPL, LGPL, and GFDL |
| |
| ## Requirement |
| |
| ```ini |
| license = "GPL-2.0-or-later AND LGPL-3.0-only" |
| ``` |
| |
| ## Config |
| |
| ```ini |
| [licenses] |
| allow = [ "GPL-3.0" ] |
| copyleft = "deny" |
| ``` |
| |
| ## Description |
| |
| GNU style licenses deviate from most of the other licenses in the SPDX license list due to the |
| way they use the `-only` and `-or-later` suffixes appended to the root name and version of the license. |
| In this example, by allowed `GPL-3.0` we satisfy the requirement of `GPL-2.0-or-later`, but because |
| we `deny` `copyleft`, the `LGPL-3.0-only` is still rejected. |
