+"Alternate Configuration Files\n"
+"-----------------------------\n"
+"nconfig supports the use of alternate configuration files for\n"
+"those who, for various reasons, find it necessary to switch\n"
+"between different kernel configurations.\n"
+"\n"
+"At the end of the main menu you will find two options.  One is\n"
+"for saving the current configuration to a file of your choosing.\n"
+"The other option is for loading a previously saved alternate\n"
+"configuration.\n"
+"\n"
+"Even if you don't use alternate configuration files, but you\n"
+"find during a nconfig session that you have completely messed\n"
+"up your settings, you may use the \"Load Alternate...\" option to\n"
+"restore your previously saved settings from \".config\" without\n"
+"restarting nconfig.\n"
+"\n"
+"Other information\n"
+"-----------------\n"
+"If you use nconfig in an XTERM window make sure you have your\n"
+"$TERM variable set to point to a xterm definition which supports color.\n"
+"Otherwise, nconfig will look rather bad.  nconfig will not\n"
+"display correctly in a RXVT window because rxvt displays only one\n"
+"intensity of color, bright.\n"
+"\n"
+"nconfig will display larger menus on screens or xterms which are\n"
+"set to display more than the standard 25 row by 80 column geometry.\n"
+"In order for this to work, the \"stty size\" command must be able to\n"
+"display the screen's current row and column geometry.  I STRONGLY\n"
+"RECOMMEND that you make sure you do NOT have the shell variables\n"
+"LINES and COLUMNS exported into your environment.  Some distributions\n"
+"export those variables via /etc/profile.  Some ncurses programs can\n"
