+
+A. HISTORY OF THE SOFTWARE
+==========================
+
+Python was created in the early 1990s by Guido van Rossum at Stichting
+Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
+as a successor of a language called ABC.  Guido remains Python's
+principal author, although it includes many contributions from others.
+
+In 1995, Guido continued his work on Python at the Corporation for
+National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
+in Reston, Virginia where he released several versions of the
+software.
+
+In May 2000, Guido and the Python core development team moved to
+BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
+year, the PythonLabs team moved to Digital Creations (now Zope
+Corporation, see http://www.zope.com).  In 2001, the Python Software
+Foundation (PSF, see http://www.python.org/psf/) was formed, a
+non-profit organization created specifically to own Python-related
+Intellectual Property.  Zope Corporation is a sponsoring member of
+the PSF.
+
+All Python releases are Open Source (see http://www.opensource.org for
+the Open Source Definition).  Historically, most, but not all, Python
+releases have also been GPL-compatible; the table below summarizes
+the various releases.
+

+Footnotes:
+
+(1) GPL-compatible doesn't mean that we're distributing Python under
+    the GPL.  All Python licenses, unlike the GPL, let you distribute
+    a modified version without making your changes open source.  The
+    GPL-compatible licenses make it possible to combine Python with
+    other software that is released under the GPL; the others don't.
+
+(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
+    because its license has a choice of law clause.  According to
+    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
+    is "not incompatible" with the GPL.
+
+Thanks to the many outside volunteers who have worked under Guido's
+direction to make these releases possible.

  <summary>The Programmers Solid 3D CAD Modeller</summary>
  <description>
   <p>OpenSCAD is a software for creating solid 3D CAD models. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.</p>
@@ -9,8 +11,12 @@
   <p>OpenSCAD provides two main modelling techniques: First there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. As data exchange format format for this 2D outlines Autocad DXF files are used. In addition to 2D paths for extrusion it is also possible to read design parameters from DXF files. Besides DXF files OpenSCAD can read and create 3D models in the STL and OFF file formats.</p>

+ZRemover
+
+This class converts one or more Nef3 polyhedra into a Nef2 polyhedron by
+stripping off the 'z' coordinates from the vertices. The resulting Nef2
+poly is accumulated in the 'output_nefpoly2d' member variable.
+
+The 'z' coordinates will either be all 0s, for an xy-plane intersected Nef3,
+or, they will be a mixture of -eps and +eps, for a thin-box intersected Nef3.
+
+Notes on CGAL's Nef Polyhedron2:
+
+1. The 'mark' on a 2d Nef face is important when doing unions/intersections.
+ If the 'mark' of a face is wrong the resulting nef2 poly will be unexpected.
+2. The 'mark' can be dependent on the points fed to the Nef2 constructor.
+ This is why we iterate through the 3d faces using the halfedge cycle
+ source()->target() instead of the ordinary source()->source(). The
+ the latter can generate sequences of points that will fail the
+ the CGAL::is_simple_2() test, resulting in improperly marked nef2 polys.
+3. 3d facets have 'two sides'. we throw out the 'down' side to prevent dups.
+
+The class uses the 'visitor' pattern from the CGAL manual. See also
+http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Nef_3/Chapter_main.html
