Hi,
it was decided that scripts bundled with Blender should be GPL licensed a number of releases back. Alas we hadn't completely followed through and lately we have allowed a few scripts that didn't have license blocks at all to slip through - doh!
So, for the owners of the following scripts - we request that you relicense your script under the GPL (ie if it is currently under another license) or if it currently lacks any license notice add the GPL license notice.
For those scripts that are not relicensed we will likely need to remove the script
