relicense under MIT license

There were several discussions why Leeroy is not licensed under
the terms of the MIT license. According to my knowledge the 2

the MIT license. To clear up confusions and not require everyone
to read all 9 sentences in License.md Leeroy is relicensed under
the terms of the MIT license.
