+
+mkufunc (make universal function) is a tool which lets you create
+a C compiled version of a universal function (UFunc).
+
+It works by translating the python function into C and then uses
+scipy.weave to create a UFunc which calls the appropriate C function
+in the inner 1-d loop.  This means that there are no Python calls
+when the calculation is performed, making the calculation
+fast (in particular when the arrays involved in the calculation
+are very large).
+
+Requirements:
+
+  pypy
+
+You need the pypy path in your PYTHONPATH environment:
+
+$ export PYTHONPATH=/giant/src/pypy-dist
+
