Copying conditions for MiKTeX
To the best of our knowledge, all software in the MiKTeX distribution is freely redistributable (libre, that is, not necessarily gratis), within the Free Software Foundation's definition and the Debian Free Software Guidelines. Where the two conflict, we generally follow the FSF. If you find any non-free files included, please contact us (reference given at the end).
That said, MiKTeX has neither a single copyright holder nor a single license covering its entire contents, since it is a collection of many independent packages. Therefore, you may copy, modify, and/or redistribute software from MiKTeX only if you comply with the requirements placed thereon by the owners of the respective packages.
To most easily learn these requirements, we suggest checking the MiKTeX package catalogue (reference given at the end). Of course the legal statements within the packages themselves are the final authority.
