+"Overview\n"
+"--------\n"
+"Some kernel features may be built directly into the kernel.\n"
+"Some may be made into loadable runtime modules.  Some features\n"
+"may be completely removed altogether.  There are also certain\n"
+"kernel parameters which are not really features, but must be\n"
+"entered in as decimal or hexadecimal numbers or possibly 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"
+"  XXX cannot be selected. use Symbol Info to find out why,\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 removed it.  You may also press the <Space Bar> to cycle\n"
+"through the available options (ie. 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\n"
+"   you wish to change use <Enter> or <Space>. Goto submenu by \n"
+"   pressing <Enter> of <right-arrow>. Use <Esc> or <left-arrow> to go back.\n"
+"   Submenus are designated 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 just press <ESC> <F5> <F8> or <left-arrow>.\n"
+"\n"
+"o  To get help with an item, press <F1>\n"
+"   Shortcut: Press <h> or <?>.\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, press <F1>\n"
+"   Shortcut: Press <H> or <?>.\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, press <F1>.\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 <SPACE BAR> for those\n"
+"   who are familiar with less and lynx.\n"

+"Alternate Configuration Files\n"
+"-----------------------------\n"
+"nconfig supports the use of alternate configuration files for\n"
+"those who, for various reasons, find it necessary to switch\n"
+"between different kernel 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 nconfig 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 nconfig.\n"
+"\n"
+"Other information\n"
+"-----------------\n"
+"If you use nconfig in an XTERM window make sure you have your\n"
+"$TERM variable set to point to a xterm definition which supports color.\n"
+"Otherwise, nconfig will look rather bad.  nconfig will not\n"
+"display correctly in a RXVT window because rxvt displays only one\n"
+"intensity of color, bright.\n"
+"\n"
+"nconfig 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 kernel options listed in a single\n"
+"menu, rather than the default multimenu hierarchy, run the nconfig\n"
+"with NCONFIG_MODE environment variable set to single_menu. Example:\n"
+"\n"
+"make NCONFIG_MODE=single_menu nconfig\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"
