The free work this toolbox is built on.
Ptah Toolbox uses free, open-source software written by other people. Their licences let anyone use the work at no cost, including in a commercial product, and nearly all of them ask for one thing in return: keep our names visible. This page is that. Every name here is linked to its own project, where the full licence text lives.
Ptah's own code is not open source and is not licensed to anyone.
