In the case of remoto's MIT license, all derivative copies of remoto are
required to contain the disclaimer text within the MIT license (as
described in the sentence "The above copyright notice and this
permission notice shall be included in all copies or substantial
portions of the Software.") So in order to ease development and
distribution of remoto, it makes sense to simply include this text in
the python package.
