| 4 | + Lua License |
| 5 | + |
| 6 | + Lua is free software: it can be used for any purpose, including |
| 7 | + commercial purposes, at absolutely no cost. No paperwork, no |
| 8 | + royalties, no GNU-like "copyleft" restrictions, either. Just download |
| 9 | + it and use it. Lua is certified Open Source software. Its licenses are |
| 10 | + compatible with GPL. Lua is not in the public domain and PUC-Rio keeps |
| 11 | + its copyright. The legal details are below. |
| 12 | + |
| 13 | + [osi certified] License for Lua 5.0 and later versions: |
| 14 | + Since Lua 5.0, Lua is licensed under the terms of the MIT license |
| 15 | + reproduced below. |
| 16 | + |
| 17 | + [open source] License for Lua 4.0 and earlier versions: |
| 18 | + Until Lua 4.0, Lua used its own license, which was very close to the |
| 19 | + zlib license and others, but not quite the same. |
| 20 | + |
| 21 | + The spirit of both licenses is that you are free to use Lua for any |
| 22 | + purpose at no cost without having to ask us. The only requirement is |
| 23 | + that if you do use Lua, then you should give us credit by including |
| 24 | + the appropriate copyright notice somewhere in your product or its |
| 25 | + documentation. A nice, but optional, way to give us further credit is |
| 26 | + to include a Lua logo and a link to our site in a web page for your |
| 27 | + product. |
| 28 | + |
| 29 | + The Lua language is entirely designed, implemented, and maintained by |
| 30 | + a team at PUC-Rio in Brazil. The implementation is not derived from |
| 31 | + licensed software. |
