Having the kconfig code in a directory called "kconfig"
and having a file called "Kconfig" causes issues if the
code is ever stored on a case-insensitive filesystem.
Avoid these by just calling the kconfig directory kconf
instead.

+ *  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.

+"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"

+"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"

+"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"

+"default mode.\n"
+"\n"
+"Different color themes available\n"

- *  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.
