+ *      docproc is a simple preprocessor for the template files
+ *      used as placeholders for the kernel internal documentation.
+ *      docproc is used for documentation-frontend and
+ *      dependency-generator.
+ *      The two usages have in common that they require
+ *      some knowledge of the .tmpl syntax, therefore they
+ *      are kept together.
+ *
+ *      documentation-frontend
+ *              Scans the template file and call kernel-doc for
+ *              all occurrences of ![EIF]file
+ *              Beforehand each referenced file are scanned for
+ *              any exported sympols "EXPORT_SYMBOL()" statements.
+ *              This is used to create proper -function and
+ *              -nofunction arguments in calls to kernel-doc.
+ *              Usage: docproc doc file.tmpl
+ *
+ *      dependency-generator:
+ *              Scans the template file and list all files
+ *              referenced in a format recognized by make.
+ *              Usage:  docproc depend file.tmpl
+ *              Writes dependency information to stdout
+ *              in the following format:
+ *              file.tmpl src.c src2.c
+ *              The filenames are obtained from the following constructs:

+ *              !Ifilename
+ *              !Dfilename

+ * "Optimize" a list of dependencies as spit out by gcc -MD
+ * for the kernel build
+ * ===========================================================================
+ *
+ * Author       Kai Germaschewski
+ * Copyright    2002 by Kai Germaschewski  <kai.germaschewski@gmx.de>
+ *
+ * This software may be used and distributed according to the terms
+ * of the GNU General Public License, incorporated herein by reference.
+ *
+ *
+ * Introduction:
+ *
+ * gcc produces a very nice and correct list of dependencies which
+ * tells make when to remake a file.
+ *
+ * To use this list as-is however has the drawback that virtually
+ * every file in the kernel includes <linux/config.h> which then again
+ * includes <linux/autoconf.h>
+ *
+ * If the user re-runs make *config, linux/autoconf.h will be
+ * regenerated.  make notices that and will rebuild every file which
+ * includes autoconf.h, i.e. basically all files. This is extremely
+ * annoying if the user just changed CONFIG_HIS_DRIVER from n to m.
+ *
+ * So we play the same trick that "mkdep" played before. We replace
+ * the dependency on linux/autoconf.h by a dependency on every config
+ * option which is mentioned in any of the listed prequisites.
+ *
+ * To be exact, split-include populates a tree in include/config/,
+ * e.g. include/config/his/driver.h, which contains the #define/#undef
+ * for the CONFIG_HIS_DRIVER option.
+ *
+ * So if the user changes his CONFIG_HIS_DRIVER option, only the objects
+ * which depend on "include/linux/config/his/driver.h" will be rebuilt,
+ * so most likely only his driver ;-)
+ *
+ * The idea above dates, by the way, back to Michael E Chastain, AFAIK.
+ *
+ * So to get dependencies right, there are two issues:
+ * o if any of the files the compiler read changed, we need to rebuild
+ * o if the command line given to the compile the file changed, we
+ *   better rebuild as well.
+ *
+ * The former is handled by using the -MD output, the later by saving
+ * the command line used to compile the old object and comparing it
+ * to the one we would now use.
+ *
+ * Again, also this idea is pretty old and has been discussed on
+ * kbuild-devel a long time ago. I don't have a sensibly working
+ * internet connection right now, so I rather don't mention names
+ * without double checking.
+ *
+ * This code here has been based partially based on mkdep.c, which
+ * says the following about its history:
+ *
+ *   Copyright abandoned, Michael Chastain, <mailto:mec@shout.net>.
+ *   This is a C version of syncdep.pl by Werner Almesberger.
+ *
+ *
+ * It is invoked as
+ *
+ *   fixdep <depfile> <target> <cmdline>
+ *
+ * and will read the dependency file <depfile>
+ *
+ * The transformed dependency snipped is written to stdout.
+ *
+ * It first generates a line
+ *
+ *   cmd_<target> = <cmdline>
+ *
+ * and then basically copies the .<target>.d file to stdout, in the
+ * process filtering out the dependency on linux/autoconf.h and adding
+ * dependencies on include/config/my/option.h for every
+ * CONFIG_MY_OPTION encountered in any of the prequisites.
+ *
+ * It will also filter out all the dependencies on *.ver. We need
+ * to make sure that the generated version checksum are globally up
+ * to date before even starting the recursive build, so it's too late
+ * at this point anyway.
+ *
+ * The algorithm to grep for "CONFIG_..." is bit unusual, but should
+ * be fast ;-) We don't even try to really parse the header files, but
+ * merely grep, i.e. if CONFIG_FOO is mentioned in a comment, it will
+ * be picked up as well. It's not a problem with respect to
+ * correctness, since that can only give too many dependencies, thus
+ * we cannot miss a rebuild. Since people tend to not mention totally
+ * unrelated CONFIG_ options all over the place, it's not an
+ * efficiency problem either.
+ *
+ * (Note: it'd be easy to port over the complete mkdep state machine,
+ *  but I don't think the added complexity is worth it)
+ */
+/*
+ * Note 2: if somebody writes HELLO_CONFIG_BOOM in a file, it will depend onto
+ * CONFIG_BOOM. This could seem a bug (not too hard to fix), but please do not
+ * fix it! Some UserModeLinux files (look at arch/um/) call CONFIG_BOOM as
+ * UML_CONFIG_BOOM, to avoid conflicts with /usr/include/linux/autoconf.h,
+ * through arch/um/include/uml-config.h; this fixdep "bug" makes sure that
+ * those files will have correct dependencies.

+ * (25/Aug/2004) Paulo Marques <pmarques@grupopie.com>
+ *      Changed the compression method from stem compression to "table lookup"
+ *      compression
+ *
+ *      Table compression uses all the unused char codes on the symbols and
+ *  maps these to the most used substrings (tokens). For instance, it might
+ *  map char code 0xF7 to represent "write_" and then in every symbol where
+ *  "write_" appears it can be replaced by 0xF7, saving 5 bytes.
+ *      The used codes themselves are also placed in the table so that the
+ *  decompresion can work without "special cases".
+ *      Applied to kernel symbols, this usually produces a compression ratio
+ *  of about 50%.

+"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 [*], <M> or [ ] represent features\n"
+"configured to be built in, modularized or removed respectively.\n"
+"Pointed brackets <> represent module capable features.\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"
+"   <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 <SPACE BAR> and <B> for those\n"
+"   who are familiar with less and lynx.\n"
+"\n"
+"o  Press <E>, <X>, <Enter> or <Esc><Esc> to exit.\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 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 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 kernel 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",

+#               Functions prototyped as foo(void) same as foo()
+#               Stop eval'ing where we don't need to.
+# -- huggie@earth.li
+
+# 27/06/2001 -  Allowed whitespace after initial "/**" and
+#               allowed comments before function declarations.
+# -- Christian Kreibich <ck@whoop.org>
+
+# Still to do:
+#       - add perldoc documentation
+#       - Look more closely at some of the scarier bits :)
+
+# 26/05/2001 -  Support for separate source and object trees.
+#               Return error code.
+#               Keith Owens <kaos@ocs.com.au>
+
+# 23/09/2001 - Added support for typedefs, structs, enums and unions
+#              Support for Context section; can be terminated using empty line
+#              Small fixes (like spaces vs. \s in regex)

+# This will read a 'c' file and scan for embedded comments in the
+# style of gnome comments (+minor extensions - see below).
+#
+
+# Note: This only supports 'c'.
+
+# usage:
+# kerneldoc [ -docbook | -html | -text | -man ]
+#           [ -function funcname [ -function funcname ...] ] c file(s)s > outputfile
+# or
+#           [ -nofunction funcname [ -function funcname ...] ] c file(s)s > outputfile
+#
+#  Set output format using one of -docbook -html -text or -man.  Default is man.
+#
+#  -function funcname
+#       If set, then only generate documentation for the given function(s).  All
+#       other functions are ignored.
+#
+#  -nofunction funcname
+#       If set, then only generate documentation for the other function(s).  All
+#       other functions are ignored. Cannot be used with -function together
+#       (yes thats a bug - perl hackers can fix it 8))
+#
+#  c files - list of 'c' files to process
+#
+#  All output goes to stdout, with errors to stderr.
+
+#
+# format of comments.
+# In the following table, (...)? signifies optional structure.
+#                         (...)* signifies 0 or more structure elements
+# /**
+#  * function_name(:)? (- short description)?
+# (* @parameterx: (description of parameter x)?)*
+# (* a blank line)?
+#  * (Description:)? (Description of function)?
+#  * (section header: (section description)? )*
+#  (*)?*/
+#
+# So .. the trivial example would be:
+#
+# /**
+#  * my_function
+#  **/
+#
+# If the Description: header tag is ommitted, then there must be a blank line
+# after the last parameter specification.
+# e.g.
+# /**
+#  * my_function - does my stuff
+#  * @my_arg: its mine damnit
+#  *
+#  * Does my stuff explained. 
+#  */
+#
+#  or, could also use:
+# /**
+#  * my_function - does my stuff
+#  * @my_arg: its mine damnit
+#  * Description: Does my stuff explained. 
+#  */
+# etc.
+#
+# Beside functions you can also write documentation for structs, unions, 
+# enums and typedefs. Instead of the function name you must write the name 
+# of the declaration;  the struct/union/enum/typedef must always precede 
+# the name. Nesting of declarations is not supported. 
+# Use the argument mechanism to document members or constants.
+# e.g.
+# /**
+#  * struct my_struct - short description
+#  * @a: first member
+#  * @b: second member
+#  * 
+#  * Longer description
+#  */
+# struct my_struct {
+#     int a;
+#     int b;
+# };
+#
+# All descriptions can be multiline, except the short function description.
+# 
+# You can also add additional sections. When documenting kernel functions you 
+# should document the "Context:" of the function, e.g. whether the functions 
+# can be called form interrupts. Unlike other sections you can end it with an
+# empty line. 
+# Example-sections should contain the string EXAMPLE so that they are marked 
+# appropriately in DocBook.
+#
+# Example:
+# /**
+#  * user_function - function that can only be called in user context
+#  * @a: some argument
+#  * Context: !in_interrupt()
+#  * 
+#  * Some description
+#  * Example:
+#  *    user_function(22);
+#  */
+# ...
+#
+#
+# All descriptive text is further processed, scanning for the following special
+# patterns, which are highlighted appropriately.
+#
+# 'funcname()' - function
+# '$ENVVAR' - environmental variable
+# '&struct_name' - name of a structure (up to two words including 'struct')
+# '@parameter' - name of a parameter
+# '%CONST' - name of a constant.

+ *  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.

+#       namespace.pl.  Mon Aug 30 2004
+#
+#       Perform a name space analysis on the linux kernel.
+#
+#       Copyright Keith Owens <kaos@ocs.com.au>.  GPL.
+#
+#       Invoke by changing directory to the top of the kernel object
+#       tree then namespace.pl, no parameters.
+#
+#       Tuned for 2.1.x kernels with the new module handling, it will
+#       work with 2.0 kernels as well.
+#
+#       Last change 2.6.9-rc1, adding support for separate source and object
+#       trees.
+#
+#       The source must be compiled/assembled first, the object files
+#       are the primary input to this script.  Incomplete or missing
+#       objects will result in a flawed analysis.  Compile both vmlinux
+#       and modules.
+#
+#       Even with complete objects, treat the result of the analysis
+#       with caution.  Some external references are only used by
+#       certain architectures, others with certain combinations of
+#       configuration parameters.  Ideally the source should include
+#       something like
+#
+#       #ifndef CONFIG_...
+#       static
+#       #endif
+#       symbol_definition;
+#
+#       so the symbols are defined as static unless a particular
+#       CONFIG_... requires it to be external.
+#
+#       A symbol that is suffixed with '(export only)' has these properties
+#
+#       * It is global.
+#       * It is marked EXPORT_SYMBOL or EXPORT_SYMBOL_GPL, either in the same
+#         source file or a different source file.
+#       * Given the current .config, nothing uses the symbol.
+#
+#       The symbol is a candidate for conversion to static, plus removal of the
+#       export.  But be careful that a different .config might use the symbol.
+#
+#
+#       Name space analysis and cleanup is an iterative process.  You cannot
+#       expect to find all the problems in a single pass.
+#
+#       * Identify possibly unnecessary global declarations, verify that they
+#         really are unnecessary and change them to static.
+#       * Compile and fix up gcc warnings about static, removing dead symbols
+#         as necessary.
+#       * make clean and rebuild with different configs (especially
+#         CONFIG_MODULES=n) to see which symbols are being defined when the
+#         config does not require them.  These symbols bloat the kernel object
+#         for no good reason, which is frustrating for embedded systems.
+#       * Wrap config sensitive symbols in #ifdef CONFIG_foo, as long as the
+#         code does not get too ugly.
+#       * Repeat the name space analysis until you can live with with the
+#         result.
