       WARNING: It looks like you are trying to trace an MPI application.
       The recommended way is to use:
-      `#{launcher} iprof cmd`
+        `#{launcher} iprof cmd`
       not
-      `iprof mpiexec cmd`
+        `iprof mpiexec cmd`
       Using `iprof #{launcher} cmd` will only profile a *single* hostname
       and may also profile the MPI launcher (e.g., PALS).
