+# The basic idea is we want to allow every use to select their own mpi
+# implementation they want, and a ${HOME}/.env.d/mpi file is created for them.
+#   A user then is -required- to source the env file.  This sets PATH, MANPATH,
+# and LD_LIBRARY_PATH.  I'm sure I'm forgetting something here.
+# Calling unset only wipes out the env file, replacing it with what we
+# previously added stripped out.
