+"Overview\n"
+"--------\n"
+"This interface lets you select features and parameters for the build.\n"
+"Features can either be built-in, modularized, or ignored. Parameters\n"
+"must be entered in as decimal or hexadecimal numbers or text.\n"
+"\n"
+"Menu items beginning with following braces represent features that\n"
+" [ ] can be built in or removed\n"
+" < > can be built in, modularized or removed\n"
+" { } can be built in or modularized (selected by other feature)\n"
+" - - are selected by other feature,\n"
+"while *, M or whitespace inside braces means to build in, build as\n"
+"a module or to exclude the feature respectively.\n"
+"\n"
+"To change any of these features, highlight it with the cursor\n"
+"keys and press <Y> to build it in, <M> to make it a module or\n"
+"<N> to remove it. You may also press the <Space Bar> to cycle\n"
+"through the available options (i.e. Y->N->M->Y).\n"
+"\n"
+"Some additional keyboard hints:\n"
+"\n"
+"Menus\n"
+"----------\n"
+"o Use the Up/Down arrow keys (cursor keys) to highlight the item you\n"
+" wish to change or the submenu you wish to select and press <Enter>.\n"
+" Submenus are designated by \"--->\", empty ones by \"----\".\n"
+"\n"
+" Shortcut: Press the option's highlighted letter (hotkey).\n"
+" Pressing a hotkey more than once will sequence\n"
+" through all visible items which use that hotkey.\n"
+"\n"
+" You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n"
+" unseen options into view.\n"
+"\n"
+"o To exit a menu use the cursor keys to highlight the <Exit> button\n"
+" and press <ENTER>.\n"
+"\n"
+" Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey\n"
+" using those letters. You may press a single <ESC>, but\n"
+" there is a delayed response which you may find annoying.\n"
+"\n"
+" Also, the <TAB> and cursor keys will cycle between <Select>,\n"
+" <Exit>, <Help>, <Save>, and <Load>.\n"
+"\n"
+"o To get help with an item, use the cursor keys to highlight <Help>\n"
+" and press <ENTER>.\n"
+"\n"
+" Shortcut: Press <H> or <?>.\n"
+"\n"
+"o To toggle the display of hidden options, press <Z>.\n"
+"\n"
+"\n"
+"Radiolists (Choice lists)\n"
+"-----------\n"
+"o Use the cursor keys to select the option you wish to set and press\n"
+" <S> or the <SPACE BAR>.\n"
+"\n"
+" Shortcut: Press the first letter of the option you wish to set then\n"
+" press <S> or <SPACE BAR>.\n"
+"\n"
+"o To see available help for the item, use the cursor keys to highlight\n"
+" <Help> and Press <ENTER>.\n"
+"\n"
+" Shortcut: Press <H> or <?>.\n"
+"\n"
+" Also, the <TAB> and cursor keys will cycle between <Select> and\n"
+" <Help>\n"
+"\n"
+"\n"
+"Data Entry\n"
+"-----------\n"
+"o Enter the requested information and press <ENTER>\n"
+" If you are entering hexadecimal values, it is not necessary to\n"
+" add the '0x' prefix to the entry.\n"
+"\n"
+"o For help, use the <TAB> or cursor keys to highlight the help option\n"
+" and press <ENTER>. You can try <TAB><H> as well.\n"
+"\n"
+"\n"
+"Text Box (Help Window)\n"
+"--------\n"
+"o Use the cursor keys to scroll up/down/left/right. The VI editor\n"
+" keys h,j,k,l function here as do <u>, <d>, <SPACE BAR> and <B> for\n"
+" those who are familiar with less and lynx.\n"
+"\n"
+"o Press <E>, <X>, <q>, <Enter> or <Esc><Esc> to exit.\n"
+"\n"
+"\n"
+"Alternate Configuration Files\n"
+"-----------------------------\n"
+"Menuconfig supports the use of alternate configuration files for\n"
+"those who, for various reasons, find it necessary to switch\n"
+"between different configurations.\n"
+"\n"
+"The <Save> button will let you save the current configuration to\n"
+"a file of your choosing. Use the <Load> button to load a previously\n"
+"saved alternate configuration.\n"
+"\n"
+"Even if you don't use alternate configuration files, but you find\n"
+"during a Menuconfig session that you have completely messed up your\n"
+"settings, you may use the <Load> button to restore your previously\n"
+"saved settings from \".config\" without 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 an xterm definition which supports\n"
+"color. Otherwise, Menuconfig will look rather bad. Menuconfig will\n"
+"not display correctly in an 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"
+"Optional personality available\n"
+"------------------------------\n"
+"If you prefer to have all of the options listed in a single menu,\n"
+"rather than the default multimenu hierarchy, run the menuconfig with\n"
+"MENUCONFIG_MODE environment variable set to single_menu. Example:\n"
+"\n"
+"make MENUCONFIG_MODE=single_menu menuconfig\n"
+"\n"
+"<Enter> will then unroll the appropriate category, or enfold it if it\n"
+"is already unrolled.\n"
+"\n"
+"Note that this mode can eventually be a little more CPU expensive\n"
+"(especially with a larger number of unrolled categories) than the\n"
+"default mode.\n"
+"\n"
+"Different color themes available\n"
+"--------------------------------\n"
+"It is possible to select different color themes using the variable\n"
+"MENUCONFIG_COLOR. To select a theme use:\n"
+"\n"
+"make MENUCONFIG_COLOR=<theme> menuconfig\n"
+"\n"
+"Available themes are\n"
+" mono => selects colors suitable for monochrome displays\n"
+" blackbg => selects a color scheme with black background\n"
+" classic => theme with blue background. The classic look\n"
+" bluetitle => an LCD friendly version of classic. (default)\n"
