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