On someone's web page I get and as well as if they provide the source code ( for example http://dev.openttdcoop.org/projects/gs- ... repository ): But How does one know what the License applies to someone else's work, in Bananas ?Licenses
In this field you'll have to select the license that applies to your work. You can select one of the predefined entries: GPL v2, GPL v3, CC-0 v1.0, CC BY v3.0, CC BY-SA v3.0, CC BY-NC-SA v3.0 or CC BY-NC-ND v3.0. If none of these licenses fit your work, select the option Custom.
If you've selected the custom option, you'll have to provide the license with your work. The license text needs to be in a file called either 'copying.txt', 'copying', 'license.txt' or 'license'.
Thank you
