+      <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)

     <para>The result is that <filename>/dev/video0</filename> and
