## 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).
