v2 as I initially forgot to remove the "v" prefix from the version number.

+     "Manifold is a geometry library dedicated to creating and operating
+     on manifold triangle meshes.  A manifold mesh is a mesh that represents
+     a solid object, and so is very important in manufacturing, CAD,
+     structural analysis, etc..  Manifold also supports arbitrary vertex
+     properties and enables mapping of materials for rendering use-cases.
+     Our primary goal is reliability: guaranteed manifold output without
+     caveats or edge cases. Our secondary goal is performance: efficient
+     algorithms that make extensive use of parallelization, or pipelining
+     when only a single thread is available.")
