+@cindex GNU Fortran command options
+@cindex command options
+@cindex options, GNU Fortran command
+
+The @code{g77} command supports all the options supported by the
+@code{gcc} command.
+@xref{Invoking GCC,,GNU CC Command Options,gcc,Using and Porting GNU CC},
+for information
+on the non-Fortran-specific aspects of the @code{gcc} command (and,
+therefore, the @code{g77} command).
+
+@cindex options, negative forms
+@cindex negative forms of options
+All @code{gcc} and @code{g77} options
+are accepted both by @code{g77} and by @code{gcc}
+(as well as any other drivers built at the same time,
+such as @code{g++}),
+since adding @code{g77} to the @code{gcc} distribution
+enables acceptance of @code{g77}-specific options
+by all of the relevant drivers.
+
+In some cases, options have positive and negative forms;
+the negative form of @samp{-ffoo} would be @samp{-fno-foo}.
+This manual documents only one of these two forms, whichever
+one is not the default.
+
+@menu
+* Option Summary::      Brief list of all @code{g77} options,
+                        without explanations.
+* Overall Options::     Controlling the kind of output:
+                        an executable, object files, assembler files,
+                        or preprocessed source.
+* Shorthand Options::   Options that are shorthand for other options.
+* Fortran Dialect Options::  Controlling the variant of Fortran language
+                             compiled.
+* Warning Options::     How picky should the compiler be?
+* Debugging Options::   Symbol tables, measurements, and debugging dumps.
+* Optimize Options::    How much optimization?
+* Preprocessor Options:: Controlling header files and macro definitions.
+                         Also, getting dependency information for Make.
+* Directory Options::   Where to find header files and libraries.
+                        Where to find the compiler executable files.
+* Code Gen Options::    Specifying conventions for function calls, data layout
+                        and register usage.
+* Environment Variables:: Env vars that affect GNU Fortran.
