+I can use a script with grep instead, but it will make some incorrect
+dependencies, since it doesn't understand about conditional compilation.
+Moreover, some dependencies may be missing, because scanning won't be
+a recursive process.
+If you have a program which generates makefile dependencies, you may want
+to use it.  If not, you can use the script and edit the Makefile by hand
