# This script is borrowed from the linux Menuconfig script.
#
# This script attempts to parse the configuration files, which are
# scattered throughout the source tree, and creates a temporary
# set of mini scripts which are in turn used to create nested menus and
# radiolists.
#
# It uses a very modified/mutilated version of the "dialog" utility
# written by Savio Lam (lam836@cs.cuhk.hk). Savio is not responsible
# for this script or the version of dialog used by this script.
# Please do not contact him with questions. The official version of 
# dialog is available at sunsite.unc.edu or a sunsite mirror.
#
# Portions of this script were borrowed from the original Configure
# script.

There seems to be a problem with the lxdialog companion utility which is
built prior to running Menuconfig.  Usually this is an indicator that you
have upgraded/downgraded your ncurses libraries and did not remove the 
old ncurses header file(s) in /usr/include or /usr/include/ncurses.

It is VERY important that you have only one set of ncurses header files
and that those files are properly version matched to the ncurses libraries 
installed on your machine.

You may also need to rebuild lxdialog.  This can be done by moving to
the scripts/lxdialog directory and issuing the 
"make clean all" command.

If you have verified that your ncurses install is correct, you may email
<fritz@wuemaus.franken.de> or post a message on the de.alt.comm.isdn4linux
news group for additional assistance.

For various reasons, one may wish to keep several different
configurations available on a single machine.  

If you have saved a previous configuration in a file other than the
default, entering the name of the file here will allow you
to modify that configuration.

If you are uncertain, then you have probably never used alternate
