## 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).
