[ros-dev] Bye bye

You MAY use the INFORMATION to implement the same functionality in ReactOS.
You MAY NOT copy (and I'm talking about copy/pasting here) the
work/implementation. This can be hard to do since one may think, why would I
want to spend hours thinking up a new implementation when I've got a
perfectly good one right in front of me? So to avoid this pitfall it is best
to describe the functionality in plain English and let another developer
implement the functionality using only the English text. A lot of work, but
this is exactly why we have copyright. Microsoft did spend even more effort
on the original implementation.

Looking on http://www.reactos.org/xhtml/en/dev_legalreview.htm
<http://www.reactos.org/xhtml/en/dev_legalreview.html>, I found:
<snip>
C. Copyrights of Others
The ReactOS Project depends on copyright law for the protection of its
code, and by the same token, it respects the copyrights of others.
Following are the policies of the ReactOS Project as they relate to
copyright:
<snip>
Disassembly of object code is held to be a form of reverse engineering.
Disassembled code listings should be treated with the same terms of
license as the object code itself.
<snip>

If I understand this correctly with my poor English, it isn't possible
to disassembly a part of windows and uses this information to implement
the same code in ReactOS.
