+## This file is a shell script fragment that supplies the information
+## necessary to tailor a template configure script into the configure
+## 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).

+### the ${host_tools} list after byacc and bison.
