+   of RTL printing in Lisp-style, the form printed by this file is called
+   "slim".  RTL dumps in slim format can be obtained by appending the "-slim"
+   option to -fdump-rtl-<pass>.  Control flow graph output as a DOT file is
+   always printed in slim form.
+
+   The normal interface to the functionality provided in this pretty-printer
+   is through the dump_*_slim functions to print to a stream, or via the
+   print_*_slim functions to print into a user's pretty-printer.
+   
+   It is also possible to obtain a string for a single pattern as a string
+   pointer, via str_pattern_slim, but this usage is discouraged.  */
