+The version of the PSCF package provided here is the original version,
+which was written in Fortran 90. A newer C++/Cuda version that allows
+use of GPU acceleration, is available in a separate github repository 
+at https://github.com/dmorse/pscfpp. Currently, the C++/Cuda version 
+and Fortran versions of PSCF each contain a few features that are not 
+available in the other code.
