  92"Alternate Configuration Files\n"
  93"-----------------------------\n"
  94"nconfig supports the use of alternate configuration files for\n"
  95"those who, for various reasons, find it necessary to switch\n"
  96"between different configurations.\n"
  97"\n"
  98"At the end of the main menu you will find two options.  One is\n"
  99"for saving the current configuration to a file of your choosing.\n"
 100"The other option is for loading a previously saved alternate\n"
 101"configuration.\n"
 102"\n"
 103"Even if you don't use alternate configuration files, but you\n"
 104"find during a nconfig session that you have completely messed\n"
 105"up your settings, you may use the \"Load Alternate...\" option to\n"
 106"restore your previously saved settings from \".config\" without\n"
 107"restarting nconfig.\n"
 108"\n"
 109"Other information\n"
 110"-----------------\n"
 111"If you use nconfig in an XTERM window make sure you have your\n"
 112"$TERM variable set to point to a xterm definition which supports color.\n"
 113"Otherwise, nconfig will look rather bad.  nconfig will not\n"
 114"display correctly in a RXVT window because rxvt displays only one\n"
 115"intensity of color, bright.\n"
 116"\n"
 117"nconfig will display larger menus on screens or xterms which are\n"
 118"set to display more than the standard 25 row by 80 column geometry.\n"
 119"In order for this to work, the \"stty size\" command must be able to\n"
 120"display the screen's current row and column geometry.  I STRONGLY\n"
 121"RECOMMEND that you make sure you do NOT have the shell variables\n"
 122"LINES and COLUMNS exported into your environment.  Some distributions\n"
 123"export those variables via /etc/profile.  Some ncurses programs can\n"
 124"become confused when those variables (LINES & COLUMNS) don't reflect\n"
 125"the true screen size.\n"
 126"\n"
 127"Optional personality available\n"
 128"------------------------------\n"
 129"If you prefer to have all of the options listed in a single menu, rather\n"
 130"than the default multimenu hierarchy, run the nconfig with NCONFIG_MODE\n"
 131"environment variable set to single_menu. Example:\n"
