PMP libraries are simple free open source software, subjected to the general policy of the PMP license.
Note: A library that is sent to be included in the PMP package becomes de facto a free open source software, free of rights of any nature. The name of the author and his comments are retained unless they go against the rules of PMP or its licensing policy. The content of the library is subject to change, to match PMP's coding rules and future features.
Even if quite limited for now, some of these libraries may need additional information that will be found here.
Libraries writers are welcome.
