                    PARTS LIBRARY AGREEMENT
1. Introduction
The following is the README text for the LDraw Parts Library
licenced by the Creative Commons Attribution Licence 2.0 as
specified by the LDraw Contributor Agreement (CA). Parts which
fall under this agreement will contain the following line in
their headers.
0 !LICENSE Redistributable under CCAL version 2.0 : see CAreadme.txt
However this text is not a license! It is simply a handy reference
for understanding the Legal Code (the full license), which can be
found in the CAlicense.txt file - it is a human-readable expression
of some key terms.  Think of it as the user-friendly interface to
the Legal Code beneath.  This text itself has no legal value and its
contents do not appear in the actual licence.  For a deeper insight
please visit: http://creativecommons.org/licenses/by/2.0/
2. Rights
You are free:
  * to copy, distribute, display, and use the CA approved LDraw
    Parts Library
  * to make derivative works
  * to make commercial use of the CA approved LDraw Parts Library
Under the following conditions:
3. Attribution.
You must give the original author credit.
  * For any reuse or distribution, you must make clear to others
    the licence terms of this library.
  * Any of these conditions can be waived if you get permission
    from the copyright holder.
The LDraw Steering Committee (SteerCo) also holds an attribution
to 'The LDraw Parts Library' in such Derivative Works to be sufficient
in lieu of a full list of authors.
Your fair use and other rights are in no way affected by the above.
4. Enforcements
The single copyright holders are the sole entity responsible for
enforcements of their copyrights. For purposes of enforcement
LDraw.org considers the following good rules of thumb to determine
if a new file is not a  Derivative work.  Anything else should be
considered a Derivative work and an attribution would be required.
If in doubt contact the current LDraw SteerCo.
What is not considered a Derivative work?
  * Rendered images generated from the LDraw library. Rendering here
    covers any conversion of a 3D model file into a 2D image.
  * Model files containing references only (the source code for the
    part may NOT be included in any form) to parts in the official
    LDraw Parts Library at the time of their creation. Part files
    which are marked as unofficial at the time of creation may be
    included in full in the model file. If the sole or main purpose (as
    determined by the LDraw SteerCo in consultation with the potentially
    offending author and LDraw community at large) of the Model file
    is to include large numbers of unofficial parts then it WILL be
    considered a derivative work.
  * Alternative libraries of parts which LDraw.org does not own or
    enforce the copyright. If some or more of the parts in the library
    are converted from the LDraw Parts Library then they must be
    considered a Derivative work.
