In development software, libraries, toolkits, gui’s etc, what licenses do I need to look for that will allow me to sell products created using the software?
Edit: I should’ve said also that I’m most interested in licenses for free development tools, however, not necessarily open source.
I certainly know of the Ms-PL (Microsoft Permissive License) but you can find a pretty good list at the CodeProject license page. The first part of the page is for uploading articles to the site but it still has a good list of licenses and their restrictions.
