## GNU LESSER GENERAL PUBLIC LICENSE |
||||
Version 3, 29 June 2007 |
||||
|
||||
 |
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
||||
Everyone is permitted to copy and distribute verbatim copies |
||||
of this license document, but changing it is not allowed. |
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates |
||||
the terms and conditions of version 3 of the GNU General Public |
||||
License, supplemented by the additional permissions listed below. |
||||
|
||||
0. Additional Definitions. |
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser |
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU |
||||
General Public License. |
||||
|
||||
"The Library" refers to a covered work governed by this License, |
||||
other than an Application or a Combined Work as defined below. |
||||
|
||||
An "Application" is any work that makes use of an interface provided |
||||
by the Library, but which is not otherwise based on the Library. |
||||
Defining a subclass of a class defined by the Library is deemed a mode |
||||
of using an interface provided by the Library. |
||||
|
||||
A "Combined Work" is a work produced by combining or linking an |
||||
Application with the Library. The particular version of the Library |
||||
with which the Combined Work was made is also called the "Linked |
||||
Version". |
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the |
||||
Corresponding Source for the Combined Work, excluding any source code |
||||
for portions of the Combined Work that, considered in isolation, are |
||||
based on the Application, and not on the Linked Version. |
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the |
||||
object code and/or source code for the Application, including any data |
||||
and utility programs needed for reproducing the Combined Work from the |
||||
Application, but excluding the System Libraries of the Combined Work. |
||||
|
||||
1. Exception to Section 3 of the GNU GPL. |
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License |
||||
without being bound by section 3 of the GNU GPL. |
||||
|
||||
2. Conveying Modified Versions. |
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a |
||||
facility refers to a function or data to be supplied by an Application |
||||
that uses the facility (other than as an argument passed when the |
||||
facility is invoked), then you may convey a copy of the modified |
||||
version: |
||||
|
||||
a) under this License, provided that you make a good faith effort to |
||||
ensure that, in the event an Application does not supply the |
||||
function or data, the facility still operates, and performs |
||||
whatever part of its purpose remains meaningful, or |
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of |
||||
this License applicable to that copy. |
||||
|
||||
3. Object Code Incorporating Material from Library Header Files. |
||||
|
||||
The object code form of an Application may incorporate material from |
||||
a header file that is part of the Library. You may convey such object |
||||
code under terms of your choice, provided that, if the incorporated |
||||
material is not limited to numerical parameters, data structure |
||||
layouts and accessors, or small macros, inline functions and templates |
||||
(ten or fewer lines in length), you do both of the following: |
||||
|
||||
a) Give prominent notice with each copy of the object code that the |
||||
Library is used in it and that the Library and its use are |
||||
covered by this License. |
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license |
||||
document. |
||||
|
||||
4. Combined Works. |
||||
|
||||
You may convey a Combined Work under terms of your choice that, |
||||
taken together, effectively do not restrict modification of the |
||||
portions of the Library contained in the Combined Work and reverse |
||||
engineering for debugging such modifications, if you also do each of |
||||
the following: |
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that |
||||
the Library is used in it and that the Library and its use are |
||||
covered by this License. |
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license |
||||
document. |
||||
|
||||
c) For a Combined Work that displays copyright notices during |
||||
execution, include the copyright notice for the Library among |
||||
these notices, as well as a reference directing the user to the |
||||
copies of the GNU GPL and this license document. |
||||
|
||||
d) Do one of the following: |
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this |
||||
License, and the Corresponding Application Code in a form |
||||
suitable for, and under terms that permit, the user to |
||||
recombine or relink the Application with a modified version of |
||||
the Linked Version to produce a modified Combined Work, in the |
||||
manner specified by section 6 of the GNU GPL for conveying |
||||
Corresponding Source. |
||||
|
||||
1) Use a suitable shared library mechanism for linking with the |
||||
Library. A suitable mechanism is one that (a) uses at run time |
||||
a copy of the Library already present on the user's computer |
||||
system, and (b) will operate properly with a modified version |
||||
of the Library that is interface-compatible with the Linked |
||||
Version. |
||||
|
||||
e) Provide Installation Information, but only if you would otherwise |
||||
be required to provide such information under section 6 of the |
||||
GNU GPL, and only to the extent that such information is |
||||
necessary to install and execute a modified version of the |
||||
Combined Work produced by recombining or relinking the |
||||
Application with a modified version of the Linked Version. (If |
||||
you use option 4d0, the Installation Information must accompany |
||||
the Minimal Corresponding Source and Corresponding Application |
||||
Code. If you use option 4d1, you must provide the Installation |
||||
Information in the manner specified by section 6 of the GNU GPL |
||||
for conveying Corresponding Source.) |
||||
|
||||
5. Combined Libraries. |
||||
|
||||
You may place library facilities that are a work based on the |
||||
Library side by side in a single library together with other library |
||||
facilities that are not Applications and are not covered by this |
||||
License, and convey such a combined library under terms of your |
||||
choice, if you do both of the following: |
||||
|
||||
a) Accompany the combined library with a copy of the same work based |
||||
on the Library, uncombined with any other library facilities, |
||||
conveyed under the terms of this License. |
||||
|
||||
b) Give prominent notice with the combined library that part of it |
||||
is a work based on the Library, and explaining where to find the |
||||
accompanying uncombined form of the same work. |
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License. |
||||
|
||||
The Free Software Foundation may publish revised and/or new versions |
||||
of the GNU Lesser General Public License from time to time. Such new |
||||
versions will be similar in spirit to the present version, but may |
||||
differ in detail to address new problems or concerns. |
||||
|
||||
Each version is given a distinguishing version number. If the |
||||
Library as you received it specifies that a certain numbered version |
||||
of the GNU Lesser General Public License "or any later version" |
||||
applies to it, you have the option of following the terms and |
||||
conditions either of that published version or of any later version |
||||
published by the Free Software Foundation. If the Library as you |
||||
received it does not specify a version number of the GNU Lesser |
||||
General Public License, you may choose any version of the GNU Lesser |
||||
General Public License ever published by the Free Software Foundation. |
||||
|
||||
If the Library as you received it specifies that a proxy can decide |
||||
whether future versions of the GNU Lesser General Public License shall |
||||
apply, that proxy's public statement of acceptance of any version is |
||||
permanent authorization for you to choose that version for the |
||||
Library. |

## Présentation du projet |
||||
|
||||
### Qu'est ce que COS2000 ? |
||||
|
||||
COS2000 est un système d'exploitation minimaliste qui vise essentiellement un objectif pédagogique. |
||||
Il s'agit avant tout du travail d'un passionné de programmation système. |
||||
|
||||
Le système est développé essentiellement en langage C mais il comporte aussi un peu d'assembleur X86. |
||||
|
||||
#### Qu'est ce qu'un système d'exploitation ? |
||||
|
||||
Il s'agit du logiciel principal qui anime votre ordinateur. Il a pour fonctions principales : |
||||
|
||||
* Piloter des périphériques tels que souris, clavier, écran, imprimante...etc; |
||||
* Gérer des fichiers qui sont produit et exploités par des applications; |
||||
* Coordonner l'accès aux ressources par plusieurs utilisateurs; |
||||
* Détection et récupération des dysfonctionnements; |
||||
* Surveiller les performances et assurer une gestion optimale des ressources systèmes. |
||||
|
||||
Sans système d'exploitation votre ordinateur est inopérant: c'est une boite vide ! |
||||
|
||||
#### Comment utiliser COS2000 ? |
||||
|
||||
COS2000 n'a pas pour but d'être utilisé en production. Il s'agit d'un système en cours de |
||||
développement que vous pouvez néanmoins tester sur un ordinateur physique ou de préférence sur une machine virtuelle. |
||||
Il est nécessaire de compiler le système avant de démarrer celui-ci à partir d'un périphérique amovible (clé usb). |
||||
|
||||
#### Sur quel ordinateur fonctionne t'il ? |
||||
|
||||
COS2000 est compatible avec tout ordinateur compatible PC comprenant un processeur avec FPU intégré, |
||||
gestion de la mémoire paginée et mode protégé : Intel Pentium et supérieur. |
||||
|
||||
#### Ai-je le droit de le copier, de le modifier, de le réutiliser, de le vendre ? |
||||
|
||||
COS2000 est sous licence LGPL v3.0, en simplifiant un peu : |
||||
|
||||
* COPIER - OUI |
||||
* MODIFIER - OUI |
||||
* REUTILISER - OUI en citant l'auteur |
||||
* VENDRE - NON |
||||
|
||||
Les détails se trouvent dans le fichier `LICENSE.md` |
||||
