Hello, According to http://en.wikipedia.org/wiki/List_of_software_licenses#GPL_2_incompatible the MS-PL is not GPL compatible. There is no reason given and I would be cautious whether this is true or not - this is Wikipedia after all. The license isn't listed among the GPL compatible and incompatible licenses at http://www.gnu.org/philosophy/license-list.html#GPLCompatibleLicenses , but ifross considers it a license with "restricted choices" - see http://www.ifross.de/ifross_html/lizenzcenter-en.html - back in 2005 the FSF Europe promised to look into the GPL compability but as fas as I can tell nothing ever got published. At http://weblogs.mozillazine.org/gerv/archives/2005/10/microsoft_annou.html you get the following opinion: > One very interesting feature of the licences, which differentiates e.g. the > Ms-PL from > the BSD licence, is that they have each got a > termination-for-patent-litigation clause. > Among other things, this makes the Ms-PL incompatible > with the GPL (or, at > least, > GPL version 2). At least in the past Microsoft Employees have contributed to GPL licensed software and the Interix product (aka SFU or Services For Unix - bought by Microsoft some time back) ships with software licensed under the GPL, i.e. gcc and lots of other tools. Microsoft's policy regarding the GPL might have changed and IANAL, too. I personally would not accept anything not GPL licensed, but in case of SAGE this is certainly not my call.
