/*
* 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:
* !Efilename
* !Ifilename
* !Dfilename
* !Ffilename

# w.o. 03-11-2000: added the '-filelist' option.
# 18/01/2001 - Cleanups
# Functions prototyped as foo(void) same as foo()
# Stop eval'ing where we don't need to.
# -- [EMAIL PROTECTED]
# 27/06/2001 - Allowed whitespace after initial "/**" and
# allowed comments before function declarations.
# -- Christian Kreibich <[EMAIL PROTECTED]>
# 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 <[EMAIL PROTECTED]>
# 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)
# -- Tim Jansen <[EMAIL PROTECTED]>
#
# 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. In
# structs and unions you must declare one member per declaration
# (comma-separated members are not allowed - the parser does not support
# this).
# 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);
# */

# 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

# 2. Function name
# 3. Function parameters.
#
# All the while we have to watch out for function pointer parameters
# (which IIRC is what the two sections are for), C types (these
# regexps don't even start to express all the possibilities), and
# so on.
#
# If you mess with these regexps, it's a good idea to check that
# the following functions' documentation still comes out right:
# - parport_register_device (function pointer parameters)
# - atomic_set (macro)
# - pci_match_device (long return type)
