| 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 | * |
