+@section How do I apply a patch?
+
+Patches generated with the @code{diff} program are fed into the
+@code{patch} program as follows:
+
+@example
+patch -p1 <PATCHFILE
+@end example
+
+where the options are:
+
+@itemize @bullet
+
+@item -pNUM tells @code{patch} to strip off NUM slashes from the
+pathname.
+
+@end itemize
+
+If @code{patch} prompts for a file to patch, you may need to adjust NUM.
