I put this documentation under the opencontent license. This means this document is given without any warranty. You can use it, redistribute it, modify it, by respecting the following conditions: You have to clearly specify the nature and the content of the modifications, their date and keep the opencontent license in case of redistribution. If you sell it, you sell the medium, not the content. This is a summary, read the license to get more details.
For those who can't read the license online, I give a textual copy:
OpenContent License (OPL)
Version 1.0, July 14, 1998.
This document outlines the principles underlying the OpenContent
(OC) movement and may be redistributed provided it remains
unaltered. For legal purposes, this document is the license under
which OpenContent is made available for use.

Terms and Conditions for Copying, Distributing, and Modifying
Items other than copying, distributing, and modifying the Content
with which this license was distributed (such as using, etc.) are
outside the scope of this license.
1. You may copy and distribute exact replicas of the OpenContent
(OC) as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any
warranty; and give any other recipients of the OC a copy of this
License along with the OC. You may at your option charge a fee for
the media and/or handling involved in creating a unique copy of the
OC for use off-line, you may at your option offer instructional
support for the OC in exchange for a fee, or you may at your option
offer warranty in exchange for a fee. You may not charge a fee for
the OC itself. You may not charge a fee for the sole service of
providing access to and/or use of the OC via a network (e.g. the
Internet), whether it be via the world wide web, FTP, or any other
method.
2. You may modify your copy or copies of the OpenContent or any
portion of it, thus forming works based on the Content, and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified content to carry prominent notices
stating that you changed it, the exact nature and content of the
changes, and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the OC or any part
thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License, unless otherwise permitted
under applicable Fair Use law.
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the OC, and
can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work
based on the OC, the distribution of the whole must be on the terms
of this License, whose permissions for other licensees extend to
the entire whole, and thus to each and every part regardless of who
wrote it. Exceptions are made to this requirement to release
modified works free of charge under this license only in compliance
with Fair Use law where applicable.
3. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to copy,
distribute or modify the OC. These actions are prohibited by law if
you do not accept this License. Therefore, by distributing or
translating the OC, or by deriving works herefrom, you indicate
your acceptance of this License to do so, and all its terms and
conditions for copying, distributing or translating the OC.
NO WARRANTY
4. BECAUSE THE OPENCONTENT (OC) IS LICENSED FREE OF CHARGE, THERE
IS NO WARRANTY FOR THE OC, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE OC "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. THE ENTIRE RISK OF USE OF THE OC IS WITH YOU.
SHOULD THE OC PROVE FAULTY, INACCURATE, OR OTHERWISE UNACCEPTABLE
YOU ASSUME THE COST OF ALL NECESSARY REPAIR OR CORRECTION.
5. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MIRROR AND/OR REDISTRIBUTE THE OC AS PERMITTED ABOVE, BE LIABLE TO
YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
THE OC, EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
