-Please watch for license conflicts. If the license indicated |
| 37 |
-by the package is incompatible with the licenses used by its sources |
| 38 |
-(e.g. BSD/MIT package including GPL sources), please contact |
| 39 |
-the licenses team for guidance. Do not add packages that seem |
| 40 |
-to include license term violations. |
| 41 |
+Please watch out for upstream licensing problems and report them |
| 42 |
+upstream. |
| 43 |
+You may ask the Gentoo licenses team for guidance. In general, it is |
| 44 |
+preferable to wait for upstream to resolve the issue and release a new |
| 45 |
+version. Do not add packages that seem to include license term |
| 46 |
+violations! |

+Common license problems include but are not limited to: |
| 51 |
+</p> |
| 52 |
+ |
| 53 |
+<ol> |
| 54 |
+ <li> |
| 55 |
+ <p> |
| 56 |
+ Including third party code without appropriate copyright notices. |
| 57 |
+ Practically all licenses (with notable exception of public |
| 58 |
+ domain-alike) require attribution, and some require copying |
| 59 |
+ original copyright notices verbatim. |
| 60 |
+ </p> |
| 61 |
+ </li> |
| 62 |
+ <li> |
| 63 |
+ <p> |
| 64 |
+ Combining incompatible licenses. When you are combining multiple |
| 65 |
+ files using different licenses into a single executable, those |
| 66 |
+ licenses need to be compatible. For example, it is not possible |
| 67 |
+ to combine proprietary code with copyleft licenses (e.g. GPL). |
| 68 |
+ It is also incorrect to combine GPL-2 (only) and GPL-3 code. |
| 69 |
+ </p> |
| 70 |
+ </li> |
| 71 |
+ <li> |
| 72 |
+ <p> |
| 73 |
+ Dynamically linking incompatible executables. Arguably, some |
| 74 |
+ licenses also apply restriction on dynamic linking between |
| 75 |
+ executables and shared libraries. For example, normally you can't |
| 76 |
+ link GPL executables with OpenSSL. The same restriction does not |
| 77 |
+ apply to LGPL, and some projects are adding specific linking |
| 78 |
+ exceptions to their GPL usage. |
| 79 |
+ </p> |
| 80 |
+ </li> |
| 81 |
+ <li> |
| 82 |
+ <p> |
| 83 |
+ Wrong or incomplete license information about a project. Upstream |
| 84 |
+ may indicate the wrong effective license for a project (e.g. |
| 85 |
+ in README. For example, upstream may indicate that the project |
| 86 |
+ is licensed as GPL-2+ while some of the source code files use |
| 87 |
+ GPL-3+ license. |
