| "those who, for various reasons, find it necessary to switch\n" |
| "between different 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 Menuconfig 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 Menuconfig.\n" |
| "\n" |
| "Other information\n" |
| "-----------------\n" |
| "If you use Menuconfig in an XTERM window make sure you have your\n" |
| "$TERM variable set to point to a xterm definition which supports color.\n" |
| "Otherwise, Menuconfig will look rather bad. Menuconfig will not\n" |
| "display correctly in a RXVT window because rxvt displays only one\n" |
| "intensity of color, bright.\n" |
| "\n" |
| "Menuconfig 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" |
| "become confused when those variables (LINES & COLUMNS) don't reflect\n" |
| "the true screen size.\n" |
| "\n" |
