+  summary: The Computational Crystallography Toolbox
+  description: |
+    The Computational Crystallography Toolbox (cctbx) is being developed
+    as the open source component of the Phenix system. The goal of the
+    Phenix project is to advance automation of macromolecular structure
+    determination. Phenix depends on the cctbx, but not vice versa. This
+    hierarchical approach enforces a clean design as a reusable library.
+    The cctbx is therefore also useful for small-molecule crystallography
+    and even general scientific applications.
