+has been specified it creates a library file and if the @samp{-z} option
+has been specified it creates a def file.  Any or all of the -e, -l
+and -z options can be present in one invocation of dlltool.
+
+When creating a DLL, along with the source for the DLL, it is necessary
+to have three other files.  @code{dlltool} can help with the creation of
+these files.
+
+The first file is a @samp{.def} file which specifies which functions are
+exported from the DLL, which functions the DLL imports, and so on.  This
+is a text file and can be created by hand, or @code{dlltool} can be used
+to create it using the @samp{-z} option.  In this case @code{dlltool}
+will scan the object files specified on its command line looking for
+those functions which have been specially marked as being exported and
+put entries for them in the .def file it creates.
+
+In order to mark a function as being exported from a DLL, it needs to
+have an @samp{-export:<name_of_function>} entry in the @samp{.drectve}
+section of the object file.  This can be done in C by using the
+asm() operator:
+
+@smallexample
+  asm (".section .drectve");  
+  asm (".ascii \"-export:my_func\"");
+
+  int my_func (void) @{ @dots{} @}
+@end smallexample
+
+The second file needed for DLL creation is an exports file.  This file
+is linked with the object files that make up the body of the DLL and it
+handles the interface between the DLL and the outside world.  This is a
+binary file and it can be created by giving the @samp{-e} option to
+@code{dlltool} when it is creating or reading in a .def file. 
+
+The third file needed for DLL creation is the library file that programs
+will link with in order to access the functions in the DLL.  This file
+can be created by giving the @samp{-l} option to dlltool when it
+is creating or reading in a .def file.
+
+@code{dlltool} builds the library file by hand, but it builds the
+exports file by creating temporary files containing assembler statements
+and then assembling these.  The @samp{-S} command line option can be
+used to specify the path to the assembler that dlltool will use,
+and the @samp{-f} option can be used to pass specific flags to that
+assembler.  The @samp{-n} can be used to prevent dlltool from deleting
+these temporary assembler files when it is done, and if @samp{-n} is
+specified twice then this will prevent dlltool from deleting the
+temporary object files it used to build the library.
+
+Here is an example of creating a DLL from a source file @samp{dll.c} and
+also creating a program (from an object file called @samp{program.o})
+that uses that DLL:
+
+@smallexample
+  gcc -c dll.c
+  dlltool -e exports.o -l dll.lib dll.o
+  gcc dll.o exports.o -o dll.dll
+  gcc program.o dll.lib -o program
+@end smallexample
+
+The command line options have the following meanings:
+
+@table @code
+
+@item -d @var{filename}
+@itemx --input-def @var{filename}
+@cindex input .def file
+Specifies the name of a .def file to be read in and processed.
+
+@item -b @var{filename}
+@itemx --base-file @var{filename}
+@cindex base files
+Specifies the name of a base file to be read in and processed.  The
+contents of this file will be added to the relocation section in the
+exports file generated by dlltool.
+
+@item -e @var{filename}
+@itemx --output-exp @var{filename}
+Specifies the name of the export file to be created by dlltool.
+
+@item -z @var{filename}
+@itemx --output-def @var{filename}
+Specifies the name of the .def file to be created by dlltool.
+
+@item -l @var{filename}
+@itemx --output-lib @var{filename}
+Specifies the name of the library file to be created by dlltool.
+
+@item --export-all-symbols
+Treat all global and weak defined symbols found in the input object
+files as symbols to be exported.  There is a small list of symbols which
+are not exported by default; see the @code{--no-default-excludes}
+option.  You may add to the list of symbols to not export by using the
+@code{--exclude-symbols} option.
+
+@item --no-export-all-symbols
+Only export symbols explicitly listed in an input .def file or in
+@samp{.drectve} sections in the input object files.  This is the default
+behaviour.  The @samp{.drectve} sections are created by @samp{dllexport}
+attributes in the source code.
+
+@item --exclude-symbols @var{list}
+Do not export the symbols in @var{list}.  This is a list of symbol names
+separated by comma or colon characters.  The symbol names should not
+contain a leading underscore.  This is only meaningful when
+@code{--export-all-symbols} is used.
+
+@item --no-default-excludes
+When @code{--export-all-symbols} is used, it will by default avoid
+exporting certain special symbols.  The current list of symbols to avoid
+exporting is @samp{DllMain@@12}, @samp{DllEntryPoint@@0},
+@samp{impure_ptr}.  You may use the @code{--no-default-excludes} option
+to go ahead and export these special symbols.  This is only meaningful
+when @code{--export-all-symbols} is used.
+
+@item -S @var{path}
+@itemx --as @var{path}
+Specifies the path, including the filename, of the assembler to be used
+to create the exports file.
+
+@item -f @var{switches}
+@itemx --as-flags @var{switches}
+Specifies any specific command line switches to be passed to the
+assembler when building the exports file.  This option will work even if
+the @samp{-S} option is not used.  This option only takes one argument,
+and if it occurs more than once on the command line, then later
+occurrences will override earlier occurrences.  So if it is necessary to
+pass multiple switches to the assembler they should be enclosed in
+double quotes.
+
+@item -D @var{name}
+@itemx --dll-name @var{name}
+Specifies the name to be stored in the .def file as the name of the DLL
+when the @samp{-e} option is used.  If this option is not present, then
+the filename given to the @samp{-e} option will be used as the name of
+the DLL.
+
+@item -m @var{machine}
+@itemx -machine @var{machine}
+Specifies the type of machine for which the library file should be
+built.  @code{dlltool} has a built in default type, depending upon how
+it was created, but this option can be used to override that.  This is
+normally only useful when creating DLLs for an ARM processor, when the
+contents of the DLL are actually encode using THUMB instructions.
+
+@item -a
+@itemx --add-indirect
+Specifies that when @code{dlltool} is creating the exports file it
+should add a section which allows the exported functions to be
+referenced without using the import library.  Whatever the hell that
+means! 
+
+@item -U
+@itemx --add-underscore
+Specifies that when @code{dlltool} is creating the exports file it
+should prepend an underscore to the names of the exported functions. 
+
+@item -k
+@itemx --kill-at
+Specifies that when @code{dlltool} is creating the exports file it
+should not append the string @samp{@@ <number>}.  These numbers are
+called ordinal numbers and they represent another way of accessing the
+function in a DLL, other than by name.
+
+@item -A
+@itemx --add-stdcall-alias
+Specifies that when @code{dlltool} is creating the exports file it
+should add aliases for stdcall symbols without @samp{@@ <number>}
+in addition to the symbols with @samp{@@ <number>}.
+
+@item -x
+@itemx --no-idata4
+Specifies that when @code{dlltool} is creating the exports and library
+files it should omit the .idata4 section.  This is for compatibility
+with certain operating systems.
+
+@item -c
+@itemx --no-idata5
+Specifies that when @code{dlltool} is creating the exports and library
+files it should omit the .idata5 section.  This is for compatibility
+with certain operating systems.
+
+@item -i
+@itemx --interwork
+Specifies that @code{dlltool} should mark the objects in the library
+file and exports file that it produces as supporting interworking
+between ARM and THUMB code.
+
+@item -n
+@itemx --nodelete
+Makes @code{dlltool} preserve the temporary assembler files it used to
+create the exports file.  If this option is repeated then dlltool will
+also preserve the temporary object files it uses to create the library
+file. 
+
+@item -v
+@itemx --verbose
+Make dlltool describe what it is doing.
+
+@item -h
+@itemx --help
+Displays a list of command line options and then exits.
+
+@item -V
+@itemx --version
+Displays dlltool's version number and then exits.
