| @node Automatic Remaking,  , Build Directories, Makefile Substitutions
| @subsection Automatic Remaking

| The @file{stamp-} files are necessary because the timestamps of
| @file{config.h.in} and @file{config.h} will not be changed if remaking
| them does not change their contents.  This feature avoids unnecessary
| recompilation.  You should include the file @file{stamp-h.in} your
| package's distribution, so @code{make} will consider @file{config.h.in}
| up to date.  On some old @sc{bsd} systems, @code{touch} or any command
| that results in an empty file does not update the timestamps, so use a
| command like @code{echo} as a workaround.

Thanks!

Do you people think we should continue explaining how to do things
without Automake?
