+MPICH for Debian
+=================
+
+MPI Alternatives
+----------------
+This package uses the Debian Alternatives system to allow you to choose
+between the different MPI implementations.
+
+You can check which version of MPI you use with
+   update-alternatives --list mpirun
+   update-alternatives --list mpi (for the development files)
+
+Use 'update-alternatives --display' to list all installed implementations,
+and 'update-alternatives --config' to configure which implementation to use.
+
+
+=================
+This work was heavily based on packaging work by Zach Lowry <zach@zachlowry.net>
+and Muammar El Khatib <muammarelkhatib@gmail.com>.
