+Usage: $0 [OPTION ...] FILE ...
+
+Read C language source or header FILEs, extract embedded documentation comments,
+and print formatted documentation to standard output.
+
+The documentation comments are identified by "/**" opening comment mark. See
+Documentation/doc-guide/kernel-doc.rst for the documentation comment syntax.
+
+Output format selection (mutually exclusive):
+ -man Output troff manual page format. This is the default.
+ -rst Output reStructuredText format.
+ -none Do not output documentation, only warnings.
+
+Output format selection modifier (affects only ReST output):
+
+ -sphinx-version Use the ReST C domain dialect compatible with an
+ specific Sphinx Version.
+ If not specified, kernel-doc will auto-detect using
+ the sphinx-build version found on PATH.
+
+Output selection (mutually exclusive):
+ -export Only output documentation for symbols that have been
+ exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()
+ in any input FILE or -export-file FILE.
+ -internal Only output documentation for symbols that have NOT been
+ exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()
+ in any input FILE or -export-file FILE.
+ -function NAME Only output documentation for the given function(s)
+ or DOC: section title(s). All other functions and DOC:
+ sections are ignored. May be specified multiple times.
+ -nosymbol NAME Exclude the specified symbols from the output
+ documentation. May be specified multiple times.
+
+Output selection modifiers:
+ -no-doc-sections Do not output DOC: sections.
+ -enable-lineno Enable output of #define LINENO lines. Only works with
+ reStructuredText format.
+ -export-file FILE Specify an additional FILE in which to look for
+ EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with
+ -export or -internal. May be specified multiple times.
+
+Other parameters:
+ -v Verbose output, more warnings and other information.
+ -h Print this help.
+ -Werror Treat warnings as errors.

+# 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 omitted, 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.
+#
+# Besides 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;
+# /* private: */
+# int c;
+# };
+#
+# All descriptions can be multiline, except the short function description.
+#
+# For really longs structs, you can also describe arguments inside the
+# body of the struct.
+# eg.
+# /**
+# * struct my_struct - short description
+# * @a: first member
+# * @b: second member
+# *
+# * Longer description
+# */
+# struct my_struct {
+# int a;
+# int b;
+# /**
+# * @c: This is longer description of C
+# *
+# * You can use paragraphs to describe arguments
+# * using this method.
+# */
+# int c;
+# };
+#
+# This should be use only for struct/enum members.
+#
+# 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.
+# A non-void function should have a "Return:" section describing the return
+# value(s).
+# 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')
+# '&struct_name.member' - name of a structure member
+# '@parameter' - name of a parameter
+# '%CONST' - name of a constant.
+# '``LITERAL``' - literal string without any spaces on it.
