 * 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.

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.
