+Gmsh with the versatility of Python. The package generalises many of
+the methods and functions that comprise the Gmsh Python API. In this
+way the meshing of complex geometries using high-level abstractions is
+made possible. The package provides a Python library together with a
+command-line utility for mesh optimisation.")
