+the form, it generates efficient low-level C++ code that can be used
+to assemble the corresponding discrete operator (tensor).  In
+particular, a bilinear form may be assembled into a matrix and a
+linear form may be assembled into a vector.  FFC may be used either
+from the command line (by invoking the @code{ffc} command) or as a
+Python module (@code{import ffc}).

+FFC is part of the FEniCS Project.")
