27 | // Dave2001, original author, founded the project in 2001, left it in 2002 |
28 | // Gugaman, joined the project in 2002, left it in 2002 |
29 | // Sergey 'Gonetz' Lipski, joined the project in 2002, main author since fall of 2002 |

34 | // To modify Glide64: |
35 | // * Write your name and (optional)email, commented by your work, so I know who did it, and so that you can find which parts you modified when it comes time to send it to me. |
36 | // * Do NOT send me the whole project or file that you modified. Take out your modified code sections, and tell me where to put them. If people sent the whole thing, I would have many different versions, but no idea how to combine them all. |
