115 | "-----------------------------\n" | |

118 | "between different kernel configurations.\n" | |
119 | "\n" | |
120 | "At the end of the main menu you will find two options. One is\n" | |
121 | "for saving the current configuration to a file of your choosing.\n" | |
122 | "The other option is for loading a previously saved alternate\n" | |
123 | "configuration.\n" | |
124 | "\n" | |
125 | "Even if you don't use alternate configuration files, but you\n" | |
126 | "find during a Menuconfig session that you have completely messed\n" | |
127 | "up your settings, you may use the \"Load Alternate...\" option to\n" | |
128 | "restore your previously saved settings from \".config\" without\n" | |
129 | "restarting Menuconfig.\n" | |
130 | "\n" | |
131 | "Other information\n" | |
132 | "-----------------\n" | |
133 | "If you use Menuconfig in an XTERM window make sure you have your\n" | |
134 | "$TERM variable set to point to a xterm definition which supports color.\n" | |
135 | "Otherwise, Menuconfig will look rather bad. Menuconfig will not\n" | |
136 | "display correctly in a RXVT window because rxvt displays only one\n" | |
137 | "intensity of color, bright.\n" | |
138 | "\n" | |
139 | "Menuconfig will display larger menus on screens or xterms which are\n" | |
140 | "set to display more than the standard 25 row by 80 column geometry.\n" | |
141 | "In order for this to work, the \"stty size\" command must be able to\n" | |
142 | "display the screen's current row and column geometry. I STRONGLY\n" | |
143 | "RECOMMEND that you make sure you do NOT have the shell variables\n" | |
144 | "LINES and COLUMNS exported into your environment. Some distributions\n" | |
145 | "export those variables via /etc/profile. Some ncurses programs can\n" | |
146 | "become confused when those variables (LINES & COLUMNS) don't reflect\n" | |
147 | "the true screen size.\n" | |
148 | "\n" | |
149 | "Optional personality available\n" | |
150 | "------------------------------\n" | |
151 | "If you prefer to have all of the kernel options listed in a single\n" | |
152 | "menu, rather than the default multimenu hierarchy, run the menuconfig\n" | |
153 | "with MENUCONFIG_MODE environment variable set to single_menu. Example:\n" | |
