2 | pj | 1 | /* Project: OSLib |
2 | * Description: The OS Construction Kit |
||
3 | * Date: 1.6.2000 |
||
4 | * Idea by: Luca Abeni & Gerardo Lamastra |
||
5 | * |
||
6 | * OSLib is an SO project aimed at developing a common, easy-to-use |
||
7 | * low-level infrastructure for developing OS kernels and Embedded |
||
8 | * Applications; it partially derives from the HARTIK project but it |
||
9 | * currently is independently developed. |
||
10 | * |
||
11 | * OSLib is distributed under GPL License, and some of its code has |
||
12 | * been derived from the Linux kernel source; also some important |
||
13 | * ideas come from studying the DJGPP go32 extender. |
||
14 | * |
||
15 | * We acknowledge the Linux Community, Free Software Foundation, |
||
16 | * D.J. Delorie and all the other developers who believe in the |
||
17 | * freedom of software and ideas. |
||
18 | * |
