+      <para>Be aware that Udev does not recognize the backslash for line
+      continuation.  This example works properly because both the backslash
+      and newline are ignored by the shell.  This makes the shell send each
+      rule to cat on only one line.  (The shell ignores this sequence because
+      the EOF string used in the here-document redirection is not enclosed in
+      either double or single quotes.  For more details, see the bash(1)
+      manpage, and search it for "Here Documents".)</para> 
+      <para>If modifying Udev rules with an editor, be sure to leave each
+      rule on one physical line.</para>
