Almost, there is no license paragraph for LGPL-2 other than the single
sentence referring to common-licenses.

I've pushed a fix for the LGPL-2+ license issue.

Thanks Bas.

Are the more details about the OTB license change elsewhere?

sorry. I wasn't clear before. the change of above license was for OSSIM not OTB. I noted because currently Modules/ThirdParty/OssimPlugins/src/ossim is using upstream license with an indication that full license text will be found in LICENSE.txt file. Since next release of ossim this will ve changed and maybe the files in Modules/ThirdParty/OssimPlugins/src/ossim

But there has been on going work on moving OTB license to Apache 2.0! .


MIT seems a better choice than CeCILL-2.0 where license compatibilty is
concerned, so in general I applaud this switch to a more common license.

A comment for the ITK derived files is an option, but not strictly required.

The Comment or Source field in the copyright header does still need to
document why 6S and SuperBuild are excluded.

I will add that. Exclusion of 6S  sources are discussed in list beofre. So I am not copy pasting here. For SuperBuild, there are patches directory in SuperBuild/patches which contains some specific patch for dependencies. currently it is a mix and excluding superbuild completely seems an easy pick.

As you said, I will include this information in copyright.

Thanks again for reviewing OTB.

I'll finish my copyright review and see what's left after that, I don't
think that'll much if any.
