+XStatic-D3
+--------------
+
+Hogan JavaScript library packaged for setuptools (easy_install) / pip.
+
+This package is intended to be used by **any** project that needs these files.
+
+It intentionally does **not** provide any extra code except some metadata
+**nor** has any extra requirements. You MAY use some minimal support code from
+the XStatic base package, if you like.
+
+You can find more info about the xstatic packaging way in the package `XStatic`.
