- *  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.

-"Some features may be built directly into libpayload.\n"
-"Some may be made into loadable runtime modules.  Some features\n"
-"may be completely removed altogether.  There are also certain\n"
-"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"
-"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"
-"\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"

-"   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"

-"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\n"
-"menu, rather than the default multimenu hierarchy, run the menuconfig\n"
-"with 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"
