+## 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).

+### To add a new directory to the tree, first choose whether it is a target
+### or a host dependent tool. Then put it into the appropriate list
+### (library or tools, host or target), doing a dependency sort. For
+### example, gdb requires that byacc (or bison) be built first, so it is in
+### the ${host_tools} list after byacc and bison.
