-## script appropriate for this directory. For more information, check
-## any existing configure script.
-
-## Be warned, there are two types of configure.in files. There are those
-## used by Autoconf, which are macros which are expanded into a configure
-## script by autoconf. The other sort, of which this is one, is executed
-## by Cygnus configure.
-
-## For more information on these two systems, check out the documentation
-## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi).
