+manifolds with associated basis function spaces, methods for lines and
+polygons, and transparent handling of coordinate reference systems and
+coordinate transformation, including @code{sf} and @code{sp} geometries.  The
+core @code{fmesher} library code was originally part of the INLA package, and
+implements parts of \"Triangulations and Applications\" by Hjelle and
+Daehlen (2006) <doi:10.1007/3-540-33261-8>.")
