%global common_description %{expand:
A Python library which uses OpenCASCADE to convert STEP files to a GLB file
which can quickly be loaded by trimesh and other libraries.

This is not intended to be a full binding of OpenCASCADE like OCP or PythonOCC.
Rather it is intended to be an easy minimal way to load boundary representation
files into a triangulated scene in Python. There are a few options for loading
STEP geometry in the open-source ecosystem: GMSH, FreeCAD, etc. However nearly
all of them use OpenCASCADE under the hood as it is pretty much the only
open-source BREP kernel.}
