Pylon: a foundation library ~ User's guide (appendix B) -- contents | previous
The licence conditions for Pylon are shown below. In a few words, the source code can be modified without restrictions but keeping the copyright and disclaimer notice. It can thus be used for commercial programs, and the library source code can also be modified and distributed with commercial products.
As a matter of common sense -- it is not a legal requirement -- modified versions of the library distributed to the public at large should be clearly marked as such.
