0116 "Alternate Configuration Files\n"
0117 "-----------------------------\n"

0120 "between different configurations.\n"
0121 "\n"
0122 "The <Save> button will let you save the current configuration to\n"

0124 "saved alternate configuration.\n"
0125 "\n"
0126 "Even if you don't use alternate configuration files, but you find\n"
0127 "during a Menuconfig session that you have completely messed up your\n"
0128 "settings, you may use the <Load> button to restore your previously\n"
0129 "saved settings from \".config\" without restarting Menuconfig.\n"
0130 "\n"
0131 "Other information\n"
0132 "-----------------\n"
0133 "If you use Menuconfig in an XTERM window, make sure you have your\n"
0134 "$TERM variable set to point to an xterm definition which supports\n"
0135 "color. Otherwise, Menuconfig will look rather bad. Menuconfig will\n"
0136 "not display correctly in an RXVT window because rxvt displays only one\n"
0137 "intensity of color, bright.\n"
0138 "\n"
0139 "Menuconfig will display larger menus on screens or xterms which are\n"
0140 "set to display more than the standard 25 row by 80 column geometry.\n"
0141 "In order for this to work, the \"stty size\" command must be able to\n"
0142 "display the screen's current row and column geometry. I STRONGLY\n"
0143 "RECOMMEND that you make sure you do NOT have the shell variables\n"
0144 "LINES and COLUMNS exported into your environment. Some distributions\n"
0145 "export those variables via /etc/profile. Some ncurses programs can\n"
0146 "become confused when those variables (LINES & COLUMNS) don't reflect\n"
0147 "the true screen size.\n"
0148 "\n"
0149 "Optional personality available\n"
0150 "------------------------------\n"
0151 "If you prefer to have all of the options listed in a single menu,\n"
0152 "rather than the default multimenu hierarchy, run the menuconfig with\n"
0153 "MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
0154 "\n"
0155 "make MENUCONFIG_MODE=single_menu menuconfig\n"
