 Inside of `/path/to/install` a `bin` directory will be created containing the `wraprun` scripts and a `lib` directory will be created containing `libsplit.so`. The `WRAPRUN_PRELOAD` environment variable must be correctly set to point to `libsplit.so` and in the case of fortran applications `libfmpich.so` at runtime.
+e.g. `WRAPRUN_PRELOAD=/path/to/install/lib/libsplit.so:/path/to/mpi_install/lib/libfmpich.so`
+
+On some systems libfmpich has a programming environment specific suffix that must be taken into account:
+e.g. `WRAPRUN_PRELOAD=/path/to/install/lib/libsplit.so:/path/to/mpi_install/lib/libfmpich_pgi.so`
 
 ## To run:
