 For longer messages one can use these two routines:
 <code Fortran>
-   CALL cp_warn(__LOCATION__,"A long warning message "\\&
+   CALL cp_warn(__LOCATION__,"A long warning message "//&
-                "which can span multiple lines and contains "\\&
+                "which can span multiple lines and contains "//&
                 "some valuable advice for the user.")
-   CALL cp_abort(__LOCATION__,"A long error message "\\&
+   CALL cp_abort(__LOCATION__,"A long error message "//&
                  "with even more valuable advises.")
 </code>
-cp_warn and CPWARN should be used sparingly, as they will produce output (and localLog files) from all MPI ranks. As such they are most useful for warning conditions that happen only on one of the ranks.
+<note important>
+Messages from ''CPWARN'' and ''cp_warn'' are only printed on the first MPI-rank.\\ Warnings issued on other ranks are ignored.
