+This library provides a Testing and Timing code
+to asses the performance of your FFT, estimate the
+scalability and the size of your simulation.
+
+To compile the test program, once you have properly
+configure QE, go inside the directory FFTXlib and
+type:
+	make TEST
+
+Then you can run your FFT tests using command like:
+
+	mpirun -np 4 ./fft_test.x -ecutwfc 80 -alat 20 
+
+or, in case of serial build
+
+	./fft_test.x -ecutwfc 80 -alat 20
