Re: [xmlvm-users] Licence issues

[Arno P. <ar...@pu...>]

yes, we do. We only accept a patch if the developer has signed a 
so-called Contributor License Agreement (CLA):

Note that the text of our CLA is a verbatim copy of Apache's CLA. Many 
other Open Source projects use the same CLA, so no surprises here.
