114 "Alternate Configuration Files\n"
115 "-----------------------------\n"

118 "between different configurations.\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"
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"
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"
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"
149 "Optional personality available\n"
150 "------------------------------\n"
151 "If you prefer to have all of the options listed in a single menu, rather\n"
152 "than the default multimenu hierarchy, run the menuconfig with\n"
153 "MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
155 "make MENUCONFIG_MODE=single_menu menuconfig\n"
157 "<Enter> will then unroll the appropriate category, or enfold it if it\n"
158 "is already unrolled.\n"
160 "Note that this mode can eventually be a little more CPU expensive\n"
161 "(especially with a larger number of unrolled categories) than the\n"
164 "Different color themes available\n"
165 "--------------------------------\n"
166 "It is possible to select different color themes using the variable\n"
167 "MENUCONFIG_COLOR. To select a theme use:\n"
169 "make MENUCONFIG_COLOR=<theme> menuconfig\n"
171 "Available themes are\n"
172 " mono => selects colors suitable for monochrome displays\n"
173 " blackbg => selects a color scheme with black background\n"
