+     NAME
+	  f2c -	Convert	Fortran	77 to C	or C++
+
+     SYNOPSIS
+	  f2c [	option ... ] file ...
+
+     DESCRIPTION
+	  F2c converts Fortran 77 source code in files with names end-
+	  ing in `.f' or `.F' to C (or C++) source files in the	cur-
+	  rent directory, with `.c' substituted	for the	final `.f' or
+	  `.F'.	 If no Fortran files are named,	f2c reads Fortran from
+	  standard input and writes C on standard output.  File	names
+	  that end with	`.p' or	`.P' are taken to be prototype files,
+	  as produced by option	`-P', and are read first.
+
+	  The following	options	have the same meaning as in f77(1).
+
+	  -C   Compile code to check that subscripts are within
+	       declared	array bounds.
+
+	  -I2  Render INTEGER and LOGICAL as short, INTEGER*4 as long
+	       int.  Assume the	default	libF77 and libI77:  allow only
+	       INTEGER*4 (and no LOGICAL) variables in INQUIREs.
+	       Option `-I4' confirms the default rendering of INTEGER
+	       as long int.
+
+	  -Idir
+	       Look for	a non-absolute include file first in the
+	       directory of the	current	input file, then in directo-
+	       ries specified by -I options (one directory per
+	       option).	 Options -I2 and -I4 have precedence, so,
+	       e.g., a directory named 2 should	be specified by	-I./2
+	       .
+
+	  -onetrip
+	       Compile DO loops	that are performed at least once if
+	       reached.	 (Fortran 77 DO	loops are not performed	at all
+	       if the upper limit is smaller than the lower limit.)
+
+	  -U   Honor the case of variable and external names.  Fortran
+	       keywords	must be	in lower case.
+
+	  -u   Make the	default	type of	a variable `undefined' rather
+	       than using the default Fortran rules.
+
+	  -w   Suppress	all warning messages, or, if the option	is
+	       `-w66', just Fortran 66 compatibility warnings.
+
+	  The following	options	are peculiar to	f2c.
+
+	  -A   Produce ANSI C (default,	starting 20020621).  For old-
+	       style C,	use option -K.

+
+     F2C(1)		       UNIX System V			F2C(1)
+
+	  -a   Make local variables automatic rather than static
+	       unless they appear in a DATA, EQUIVALENCE, NAMELIST, or
+	       SAVE statement.
+
+	  -C++ Output C++ code.
+
+	  -c   Include original	Fortran	source as comments.
+
+	  -cd  Do not recognize	cdabs, cdcos, cdexp, cdlog, cdsin, and
+	       cdsqrt as synonyms for the double complex intrinsics
+	       zabs, zcos, zexp, zlog, zsin, and zsqrt,	respectively,
+	       nor dreal as a synonym for dble.
+
+	  -ddir
+	       Write `.c' files	in directory dir instead of the	cur-
+	       rent directory.
+
+	  -E   Declare uninitialized COMMON to be Extern (overridably
+	       defined in f2c.h	as extern).
+
+	  -ec  Place uninitialized COMMON blocks in separate files:
+	       COMMON /ABC/ appears in file abc_com.c.	Option `-e1c'
+	       bundles the separate files into the output file,	with
+	       comments	that give an unbundling	sed(1) script.
+
+	  -ext Complain	about f77(1) extensions.
+
+	  -f   Assume free-format input: accept	text after column 72
+	       and do not pad fixed-format lines shorter than 72 char-
+	       acters with blanks.
+
+	  -72  Treat text appearing after column 72 as an error.
+
+	  -g   Include original	Fortran	line numbers in	#line lines.
+
+	  -h   Emulate Fortran 66's treatment of Hollerith: try	to
+	       align character strings on word (or, if the option is
+	       `-hd', on double-word) boundaries.
+
+	  -i2  Similar to -I2, but assume a modified libF77 and	libI77
+	       (compiled with -Df2c_i2), so INTEGER and	LOGICAL	vari-
+	       ables may be assigned by	INQUIRE	and array lengths are
+	       stored in short ints.
+
+	  -i90 Do not recognize	the Fortran 90 bit-manipulation
+	       intrinsics btest, iand, ibclr, ibits, ibset, ieor, ior,
+	       ishft, and ishftc.
+
+	  -kr  Use temporary values to enforce Fortran expression
+	       evaluation where	K&R (first edition) parenthesization
+	       rules allow rearrangement.  If the option is `-krd',
+	       use double precision temporaries	even for single-
+
+     Page 2					     (printed 6/21/02)
+
+     F2C(1)		       UNIX System V			F2C(1)
+
+	       precision operands.
+
+	  -P   Write a file.P of ANSI (or C++) prototypes for defini-
+	       tions in	each input file.f or file.F.  When reading
+	       Fortran from standard input, write prototypes at	the
+	       beginning of standard output.  Option -Ps implies -P
+	       and gives exit status 4 if rerunning f2c	may change
+	       prototypes or declarations.
+
+	  -p   Supply preprocessor definitions to make common-block
+	       members look like local variables.
+
+	  -R   Do not promote REAL functions and operations to DOUBLE
+	       PRECISION.  Option `-!R'	confirms the default, which
+	       imitates	f77.
+
+	  -r   Cast REAL arguments of intrinsic	functions and values
+	       of REAL functions (including intrinsics)	to REAL.
+
+	  -r8  Promote REAL to DOUBLE PRECISION, COMPLEX to DOUBLE
+	       COMPLEX.
+
+	  -s   Preserve	multidimensional subscripts.  Suppressed by
+	       option `-C' .
+
+	  -Tdir
+	       Put temporary files in directory	dir.
+
+	  -trapuv
+	       Dynamically initialize local variables, except those
+	       appearing in SAVE or DATA statements, with values that
+	       may help	find references	to uninitialized variables.
+	       For example, with IEEE arithmetic, initialize local
+	       floating-point variables	to signaling NaNs.
+
+	  -w8  Suppress	warnings when COMMON or	EQUIVALENCE forces
+	       odd-word	alignment of doubles.
+
+	  -Wn  Assume n	characters/word	(default 4) when initializing
+	       numeric variables with character	data.
+
+	  -z   Do not implicitly recognize DOUBLE COMPLEX.
+
+	  -!bs Do not recognize	backslash escapes (\", \', \0, \\, \b,
+	       \f, \n, \r, \t, \v) in character	strings.
+
+	  -!c  Inhibit C output, but produce -P	output.
+
+	  -!I  Reject include statements.
+
+	  -!i8 Disallow	INTEGER*8 , or,	if the option is `-!i8const',
+	       permit INTEGER*8	but do not promote integer constants
+
+     Page 3					     (printed 6/21/02)
+
+     F2C(1)		       UNIX System V			F2C(1)
+
+	       to INTEGER*8 when they involve more than	32 bits.
+
+	  -!it Don't infer types of untyped EXTERNAL procedures	from
+	       use as parameters to previously defined or prototyped
+	       procedures.
+
+	  -!P  Do not attempt to infer ANSI or C++ prototypes from
+	       usage.
+
+	  The resulting	C invokes the support routines of f77; object
+	  code should be loaded	by f77 or with ld(1) or	cc(1) options
+	  -lF77	-lI77 -lm.  Calling conventions	are those of f77: see
+	  the reference	below.

+     DIAGNOSTICS
+	  The diagnostics produced by f2c are intended to be self-
+	  explanatory.
+
+     BUGS
+	  Floating-point constant expressions are simplified in	the
+	  floating-point arithmetic of the machine running f2c,	so
+	  they are typically accurate to at most 16 or 17 decimal
+	  places.
+	  Untypable EXTERNAL functions are declared int.
+	  There	is no notation for INTEGER*8 constants.
+	  Some intrinsic functions do not yet work with	INTEGER*8 .
