+/*
+ * Changes by Clifford Wolf (god@clifford.at)
+ *
+ * [ 1998-06-13 ]
+ *
+ * *) A bugfix for the Page-Down problem
+ *
+ * *) Formerly when I used Page Down and Page Up, the cursor would be set
+ * to the first position in the menu box. Now lxdialog is a bit
+ * smarter and works more like other menu systems (just have a look at
+ * it).
+ *
+ * *) Formerly if I selected something my scrolling would be broken because
+ * lxdialog is re-invoked by the Menuconfig shell script, can't
+ * remember the last scrolling position, and just sets it so that the
+ * cursor is at the bottom of the box. Now it writes the temporary file
+ * lxdialog.scrltmp which contains this information. The file is
+ * deleted by lxdialog if the user leaves a submenu or enters a new
+ * one, but it would be nice if Menuconfig could make another "rm -f"
+ * just to be sure. Just try it out - you will recognise a difference!
+ *
+ * [ 1998-06-14 ]
+ *
+ * *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ * and menus change their size on the fly.
+ *
+ * *) If for some reason the last scrolling position is not saved by
+ * lxdialog, it sets the scrolling so that the selected item is in the
+ * middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+"Overview\n"
+"--------\n"
+"This interface let 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 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 or submenu wish to select and press <Enter>.\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 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> and <Help>.\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"
+"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 Menuconfig 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 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 a xterm definition which supports color.\n"
+"Otherwise, Menuconfig will look rather bad. Menuconfig will not\n"
+"display correctly in a 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, rather\n"
+"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 => a LCD friendly version of classic. (default)\n"
