+@code{windres} may be used to manipulate Windows resources.
+
+@quotation
+@emph{Warning:} @code{windres} is not always built as part of the binary
+utilities, since it is only useful for Windows targets.
+@end quotation

+@end smallexample
+
+@code{windres} reads resources from an input file and copies them into
+an output file.  Either file may be in one of three formats:
+
+@table @code
+@item rc
+A text format read by the Resource Compiler.
+
+@item res
+A binary format generated by the Resource Compiler.
+
+@item coff
+A COFF object or executable.
+@end table
+
+The exact description of these different formats is available in
+documentation from Microsoft.
+
+When @code{windres} converts from the @code{rc} format to the @code{res}
+format, it is acting like the Windows Resource Compiler.  When
+@code{windres} converts from the @code{res} format to the @code{coff}
+format, it is acting like the Windows @code{CVTRES} program.
+
+When @code{windres} generates an @code{rc} file, the output is similar
+but not identical to the format expected for the input.  When an input
+@code{rc} file refers to an external filename, an output @code{rc} file
+will instead include the file contents.
+
+If the input or output format is not specified, @code{windres} will
+guess based on the file name, or, for the input file, the file contents.
+A file with an extension of @file{.rc} will be treated as an @code{rc}
+file, a file with an extension of @file{.res} will be treated as a
+@code{res} file, and a file with an extension of @file{.o} or
+@file{.exe} will be treated as a @code{coff} file.
+
+If no output file is specified, @code{windres} will print the resources
+in @code{rc} format to standard output.
+
+The normal use is for you to write an @code{rc} file, use @code{windres}
+to convert it to a COFF object file, and then link the COFF file into
+your application.  This will make the resources described in the
+@code{rc} file available to Windows.
+
+@table @code
+@item -i @var{filename}
+@itemx --input @var{filename}
+The name of the input file.  If this option is not used, then
+@code{windres} will use the first non-option argument as the input file
+name.  If there are no non-option arguments, then @code{windres} will
+read from standard input.  @code{windres} can not read a COFF file from
+standard input.
+
+@item -o @var{filename}
+@itemx --output @var{filename}
+The name of the output file.  If this option is not used, then
+@code{windres} will use the first non-option argument, after any used
+for the input file name, as the output file name.  If there is no
+non-option argument, then @code{windres} will write to standard output.
+@code{windres} can not write a COFF file to standard output.
+
+@item -I @var{format}
+@itemx --input-format @var{format}
+The input format to read.  @var{format} may be @samp{res}, @samp{rc}, or
+@samp{coff}.  If no input format is specified, @code{windres} will
+guess, as described above.
+
+@item -O @var{format}
+@itemx --output-format @var{format}
+The output format to generate.  @var{format} may be @samp{res},
+@samp{rc}, or @samp{coff}.  If no output format is specified,
+@code{windres} will guess, as described above.
+
+@item -F @var{target}
+@itemx --target @var{target}
+Specify the BFD format to use for a COFF file as input or output.  This
+is a BFD target name; you can use the @code{--help} option to see a list
+of supported targets.  Normally @code{windres} will use the default
+format, which is the first one listed by the @code{--help} option.
+@ref{Target Selection}.
+
+@item --preprocessor @var{program}
+When @code{windres} reads an @code{rc} file, it runs it through the C
+preprocessor first.  This option may be used to specify the preprocessor
+to use, including any leading arguments.  The default preprocessor
+argument is @code{gcc -E -xc-header -DRC_INVOKED}.
+
+@item --include-dir @var{directory}
+Specify an include directory to use when reading an @code{rc} file.
+@code{windres} will pass this to the preprocessor as an @code{-I}
+option.  @code{windres} will also search this directory when looking for
+files named in the @code{rc} file.
+
+@item --define @var{sym[=val]}
+Specify a @code{-D} option to pass to the preprocessor when reading an
+@code{rc} file.
+
+@item --language @var{val}
+Specify the default language to use when reading an @code{rc} file.
+@var{val} should be a hexadecimal language code.  The low eight bits are
+the language, and the high eight bits are the sublanguage.
+
+@item --help
+Prints a usage summary.
+
+@item --version
+Prints the version number for @code{windres}.
+
+@item --yydebug
+If @code{windres} is compiled with @code{YYDEBUG} defined as @code{1},
+this will turn on parser debugging.
