+.SH DESCRIPTION
+GNU \c
+.B as\c
+\& is really a family of assemblers.
+If you use (or have used) the GNU assembler on one architecture, you
+should find a fairly similar environment when you use it on another
+architecture. Each version has much in common with the others,
+including object file formats, most assembler directives (often called
+\c
+.I pseudo-ops)\c
+\& and assembler syntax.
+
+For information on the syntax and pseudo-ops used by GNU \c
+.B as\c
+\&, see `\|\c
+.B as\c
+\|' entry in \c
+.B info \c
+(or the manual \c
+.I
+.I
+Using as: The GNU Assembler\c
+\&).
+
+\c
+.B as\c
+\& is primarily intended to assemble the output of the GNU C
+compiler \c
+.B gcc\c
+\& for use by the linker \c
+.B ld\c
+\&. Nevertheless,
+we've tried to make \c
+.B as\c
+\& assemble correctly everything that the native
+assembler would.
+This doesn't mean \c
+.B as\c
+\& always uses the same syntax as another
+assembler for the same architecture; for example, we know of several
+incompatible versions of 680x0 assembly language syntax.
+
+Each time you run \c
+.B as\c
+\& it assembles exactly one source
+program. The source program is made up of one or more files.
+(The standard input is also a file.)
+
+If \c
+.B as\c
+\& is given no file names it attempts to read one input file
+from the \c
+.B as\c
+\& standard input, which is normally your terminal. You
+may have to type \c
+.B ctl-D\c
+\& to tell \c
+.B as\c
+\& there is no more program
+to assemble. Use `\|\c
+.B \-\^\-\c
+\|' if you need to explicitly name the standard input file
+in your command line.
+
+.B as\c
+\& may write warnings and error messages to the standard error
+file (usually your terminal). This should not happen when \c
+.B as\c
+\& is
+run automatically by a compiler. Warnings report an assumption made so
+that \c
+.B as\c
+\& could keep assembling a flawed program; errors report a
+grave problem that stops the assembly.
+
+.SH OPTIONS
+.TP
+.BR \-a
+Turn on assembly listings. There are various suboptions.
+.B d
+omits debugging directives.
+.B h
+includes the high level source code; this is only available if the
+source file can be found, and the code was compiled with
+.B \-g.
+.B l
+includes an assembly listing.
+.B n
+omits forms processing.
+.B s
+includes a symbol listing.
+.B =
+.I file
+sets the listing file name; this must be the last suboption.
+The default suboptions are
+.B hls.
+.TP
+.B \-D
+This option is accepted only for script compatibility with calls to
+other assemblers; it has no effect on \c
+.B as\c
+\&.
+.TP
+.B \-\-defsym SYM=VALUE
+Define the symbol SYM to be VALUE before assembling the input file.
+VALUE must be an integer constant. As in C, a leading 0x indicates a
+hexadecimal value, and a leading 0 indicates an octal value.
+.TP
+.B \-f
+``fast''--skip preprocessing (assume source is compiler output).
+.TP
+.BI "\-I\ " path
+Add
+.I path
+to the search list for
+.B .include
+directives.
+.TP
+.B \-\-gstabs
+Generate stabs debugging information for each assembler line. This
+may help debugging assembler code, if the debugger can handle it.
+.TP
+.B \-K
+Issue warnings when difference tables altered for long displacements.
+.TP
+.B \-L
+Keep (in symbol table) local symbols, starting with `\|\c
+.B L\c
+\|'
+.TP
+.B \-M, \-\-mri
+Assemble in MRI compatibility mode.
+.TP
+.BI "\-o\ " objfile
+Name the object-file output from \c
+.B as
+.TP
+.B \-R
+Fold data section into text section
+.TP
+.B \-\-traditional\-format
+Use same format as native assembler, when possible.
+.TP
+.B \-v
+Announce \c
+.B as\c
+\& version
+.TP
+.B \-W
+Suppress warning messages
+.TP
+.IR "\-\^\-" "\ |\ " "files\|.\|.\|."
+Source files to assemble, or standard input (\c
+.BR "\-\^\-" ")"
+.TP
+.BI \-A var
+.I
+(When configured for Intel 960.)
+Specify which variant of the 960 architecture is the target.
+.TP
+.B \-b
+.I
+(When configured for Intel 960.)
+Add code to collect statistics about branches taken.
+.TP
+.B \-no-relax
+.I
+(When configured for Intel 960.)
+Do not alter compare-and-branch instructions for long displacements;
+error if necessary.
+.TP
+.B \-l
+.I
+(When configured for Motorola 68000).
+.br
+Shorten references to undefined symbols, to one word instead of two.
+.TP
+.BR "\-mc68000" "\||\|" "\-mc68010" "\||\|" "\-mc68020"
+.I
+(When configured for Motorola 68000).
+.br
+Specify what processor in the 68000 family is the target (default 68020)
+
+.PP
+Options may be in any order, and may be
+before, after, or between file names. The order of file names is
+significant.
+
+`\|\c
+.B \-\^\-\c
+\|' (two hyphens) by itself names the standard input file
+explicitly, as one of the files for \c
+.B as\c
+\& to assemble.
+
+Except for `\|\c
+.B \-\^\-\c
+\|' any command line argument that begins with a
+hyphen (`\|\c
+.B \-\c
+\|') is an option. Each option changes the behavior of
+\c
+.B as\c
+\&. No option changes the way another option works. An
+option is a `\|\c
+.B \-\c
+\|' followed by one or more letters; the case of
+the letter is important. All options are optional.
+
+The `\|\c
+.B \-o\c
+\|' option expects exactly one file name to follow. The file
+name may either immediately follow the option's letter (compatible
+with older assemblers) or it may be the next command argument (GNU
+standard).
+
+These two command lines are equivalent:
+.br
+.B
+as\ \ \-o\ \ my\-object\-file.o\ \ mumble.s
+.br
+.B
+as\ \ \-omy\-object\-file.o\ \ mumble.s
