-.SH DESCRIPTION
-This manual page describes the GNU version of
-.BR eqn ,
-which is part of the groff document formatting system.
-.B eqn
-compiles descriptions of equations embedded within
-.B troff
-input files into commands that are understood by
-.BR troff .
-Normally, it should be invoked using the
-.B \-e
-option of
-.BR groff .
-The syntax is quite compatible with Unix eqn.
-The output of GNU eqn cannot be processed with Unix troff;
-it must be processed with GNU troff.
-If no files are given on the command line, the standard input
-will be read.
-A filename of
-.B \-
-will cause the standard input to be read.
-.LP
-.B eqn
-searches for the file
-.B eqnrc
-using the path
-.BR @MACROPATH@ .
-If it exists, eqn will process it before the other input files.
-The
-.B \-R
-option prevents this.
-.LP
-GNU eqn does not provide the functionality of neqn:
-it does not support low-resolution, typewriter-like devices
-(although it may work adequately for very simple input).
-.SH OPTIONS
-.TP
-.B \-C
-Recognize
-.B .EQ
-and
-.B .EN
-even when followed by a character other than space or newline.
-.TP
-.B \-N
-Don't allow newlines within delimiters.
-This option allows
-.B eqn
-to recover better from missing closing delimiters.
-.TP
-.B \-v
-Print the version number.
-.TP
-.B \-r
-Only one size reduction.
-.TP
-.BI \-m n
-The minimum point-size is
-.IR n .
-eqn will not reduce the size of subscripts or superscripts to
-a smaller size than
-.IR n .
-.TP
-.BI \-T name
-The output is for device
-.IR name .
-The only effect of this is to define a macro
-.I name
-with a value of
-.BR 1 .
-Typically
-.B eqnrc
-will use this to provide definitions appropriate for the output device.
-The default output device is
-.BR @DEVICE@ .
-.TP
-.BI \-M dir
-Search
-.I dir
-for
-.B eqnrc
-before the default directories.
-.TP
-.B \-R
-Don't load
-.BR eqnrc .
-.TP
-.BI \-f F
-This is equivalent to a
-.BI gfont\  F
-command.
-.TP
-.BI \-s n
-This is equivalent to a
-.BI gsize\  n
-command.
-This option is deprecated.
-eqn will normally set equations at whatever the current point size
-is when the equation is encountered.
-.TP
-.BI \-p n
-This says that subscripts and superscripts should be
-.I n
-points smaller than the surrounding text.
-This option is deprecated. 
-Normally eqn makes sets subscripts and superscripts at 70% 
-of the size of the surrounding text.
-.SH USAGE
-Only the differences between GNU eqn and Unix eqn are described here.
-.LP
-Most of the new features of GNU eqn
-are based on \*(tx.
-There are some references to the differences between \*(tx and GNU eqn below;
-these may safely be ignored if you do not know \*(tx.
-.SS Automatic spacing
-.LP
-.B eqn
-gives each component of an equation a type, and adjusts the spacing
-between components using that type.
-Possible types are:
-.TP \w'punctuation'u+2n
-ordinary
-an ordinary character such as 1 or
-.IR x ;
-.TP
-operator
-a large operator such as
-.ds Su \s+5\(*S\s0
-.if \n(.g .if !c\(*S .ds Su the summation operator
-\*(Su;
-.TP
-binary
-a binary operator such as +;
-.TP
-relation
-a relation such as =;
-.TP
-opening
-a opening bracket such as (;
-.TP
-closing
-a closing bracket such as );
-.TP
-punctuation
-a punctuation character such as ,;
-.TP
-inner
-a subformula contained within brackets;
-.TP
-suppress
-spacing that suppresses automatic spacing adjustment.
-.LP
-Components of an equation get a type in one of two ways.
-.TP
-.BI type\  t\ e
-This yields an equation component that contains
-.I e
-but that has type
-.IR t ,
-where
-.I t
-is one of the types mentioned above.
-For example,
-.B times
-is defined as
-.RS
-.IP
-.B
-type "binary" \e(mu
-.RE
-.IP
-The name of the type doesn't have to be quoted, but quoting protects
-from macro expansion.
-.TP
-.BI chartype\  t\ text
-Unquoted groups of characters are split up into individual characters,
-and the type of each character is looked up;
-this changes the type that is stored for each character;
-it says that the characters in
-.I text
-from now on have type
-.IR t .
-For example,
-.RS
-.IP
-.B
-chartype "punctuation" .,;:
-.RE
-.IP
-would make the characters
-.B .,;:
-have type punctuation
-whenever they subsequently appeared in an equation.
-The type
-.I t
-can also be
-.B letter
-or
-.BR digit ;
-in these cases
-.B chartype
-changes the font type of the characters.
-See the Fonts subsection.
-.SS New primitives
-.TP
-.IB e1\  smallover\  e2
-This is similar to
-.BR over ;
-.B smallover
-reduces the size of
-.I e1
-and
-.IR e2 ;
-it also puts less vertical space between
-.I e1
-or
-.I e2
-and the fraction bar.
-The
-.B over
-primitive corresponds to the \*(tx
-.B \eover
-primitive in display styles;
-.B smallover
-corresponds to
-.B \eover
-in non-display styles.
-.TP
-.BI vcenter\  e
-This vertically centers
-.I e
-about the math axis.
-The math axis is the vertical position about which characters
-such as + and - are centered; also it is the vertical position
-used for the bar of fractions.
-For example,
-.B sum
-is defined as
-.RS
-.IP
-.B
-{ type "operator" vcenter size +5 \e(*S }
-.RE
-.TP
-.IB e1\  accent\  e2
-This sets
-.I e2
-as an accent over
-.IR e1 .
-.I e2
-is assumed to be at the correct height for a lowercase letter;
-.I e2
-will be moved down according if
-.I e1
-is taller or shorter than a lowercase letter.
-For example,
-.B hat
-is defined as
-.RS
-.IP
-.B
-accent { "^" }
-.RE
-.IP
-.BR dotdot ,
-.BR dot ,
-.BR tilde ,
-.B vec
-and
-.B dyad
-are also defined using the
-.B accent
-primitive.
-.TP
-.IB e1\  uaccent\  e2
-This sets
-.I e2
-as an accent under
-.IR e1 .
-.I e2
-is assumed to be at the correct height for a character without a descender;
-.I e2
-will be moved down if
-.I e1
-has a descender.
-.B utilde
-is pre-defined using
-.B uaccent
-as a tilde accent below the baseline.
-.TP
-.BI split\ \(ts text \(ts
-This has the same effect as simply
-.RS
-.IP
-.I text
-.RE
-.IP
-but
-.I text
-is not subject to macro expansion because it is quoted;
-.I text
-will be split up and the spacing between individual characters
-will be adjusted.
-.TP
-.BI nosplit\  text
-This has the same effect as
-.RS
-.IP
-.BI \(ts text \(ts
-.RE
-.IP
-but because
-.I text
-is not quoted it will be subject to macro expansion;
-.I text
-will not be split up
-and the spacing between individual characters will not be adjusted.
-.TP
-.IB e\  opprime
-This is a variant of
-.B prime
-that acts as an operator on
-.IR e .
-It produces a different result from
-.B prime
-in a case such as
-.BR A\ opprime\ sub\ 1 :
-with
-.B opprime
-the
-.B 1
-will be tucked under the prime as a subscript to the
-.B A
-(as is conventional in mathematical typesetting),
-whereas with
-.B prime
-the
-.B 1
-will be a subscript to the prime character.
-The precedence of
-.B opprime
-is the same as that of
-.B bar
-and
-.BR under ,
-which is higher than that of everything except
-.B accent
-and
-.BR uaccent .
-In unquoted text a
-.B '
-that is not the first character will be treated like
-.BR opprime .
-.TP
-.BI special\  text\ e
-This constructs a new object from
-.I e
-using a
-.BR @g@troff  (@MAN1EXT@)
-macro named
-.IR text .
-When the macro is called,
-the string
-.B 0s
-will contain the output for
-.IR e ,
-and the number registers
-.BR 0w ,
-.BR 0h ,
-.BR 0d ,
-.BR 0skern
-and
-.BR 0skew
-will contain the width, height, depth, subscript kern, and skew of
-.IR e .
-(The
-.I "subscript kern"
-of an object says how much a subscript on that object should be tucked in;
-the
-.I skew
-of an object says how far to the right of the center of the object an
-accent over the object should be placed.)
-The macro must modify
-.B 0s
-so that it will output the desired result with its origin at the current
-point, and increase the current horizontal position by the width
-of the object.
-The number registers must also be modified so that they correspond to the
-result.
-.RS

-For example, suppose you wanted a construct that `cancels' an expression
-by drawing a diagonal line through it.

-.RE
-.SS Customization
-The appearance of equations is controlled by
-a large number of parameters. These can be set using
-the
-.B set
-command.
-.TP
-.BI set\  p\ n
-This sets parameter
-.I p
-to value
-.I n ;
-.I n
-is an integer.
-For example,
-.RS
-.IP
-.B
-set x_height 45
-.RE
-.IP
-says that
-.B eqn
-should assume an x height of 0.45 ems.
-.RS
-.LP
-Possible parameters are as follows.
-Values are in units of hundredths of an em unless otherwise stated.
-These descriptions are intended to be expository rather than
-definitive.
-.TP \w'\fBdefault_rule_thickness'u+2n
-.B minimum_size
-.B eqn
-will not set anything at a smaller point-size than this.
-The value is in points.
-.TP
-.B fat_offset
-The
-.B fat
-primitive emboldens an equation
-by overprinting two copies of the equation
-horizontally offset by this amount.
-.TP
-.B over_hang
-A fraction bar will be longer by twice this amount than
-the maximum of the widths of the numerator and denominator;
-in other words, it will overhang the numerator and
-denominator by at least this amount.
-.TP
-.B accent_width
-When
-.B bar
-or
-.B under
-is applied to a single character,
-the line will be this long.
-Normally,
-.B bar
-or
-.B under
-produces a line whose length is the width of the object to which it applies;
-in the case of a single character,
-this tends to produce a line that looks too long.
-.TP
-.B delimiter_factor
-Extensible delimiters produced with the
-.B left
-and
-.B right
-primitives will have a combined height and depth of at least this many
-thousandths of twice the maximum amount by which the sub-equation that
-the delimiters enclose extends away from the axis.
-.TP
-.B delimiter_shortfall
-Extensible delimiters produced with the
-.B left
-and
-.B right
-primitives will have a combined height and depth
-not less than the difference of
-twice the maximum amount by which the sub-equation that
-the delimiters enclose extends away from the axis
-and this amount.
-.TP
-.B null_delimiter_space
-This much horizontal space is inserted
-on each side of a fraction.
-.TP
-.B script_space
-The width of subscripts and superscripts is increased by this amount.
-.TP
-.B thin_space
-This amount of space is automatically inserted after punctuation
-characters.
-.TP
-.B medium_space
-This amount of space is automatically inserted on either side
-of binary operators.
-.TP
-.B thick_space
-This amount of space is automatically inserted on either side of
-relations.
-.TP
-.B x_height
-The height of lowercase letters without ascenders such as x.
-.TP
-.B axis_height
-The height above the baseline of the center of characters
-such as \(pl and \(mi.
-It is important that this value is correct for the font
-you are using.
-.TP
-.B default_rule_thickness
-This should set to the thickness of the
-.B \e(ru
-character, or the thickness of horizontal lines produced with the
-.B \eD
-escape sequence.
-.TP
-.B num1
-The
-.B over
-command will shift up the numerator by at least this amount.
-.TP
-.B num2
-The
-.B smallover
-command will shift up the numerator by at least this amount.
-.TP
-.B denom1
-The
-.B over
-command will shift down the denominator by at least this amount.
-.TP
-.B denom2
-The
-.B smallover
-command will shift down the denominator by at least this amount.
-.TP
-.B sup1
-Normally superscripts will be shifted up by at least this amount.
-.TP
-.B sup2
-Superscripts within superscripts or upper limits
-or numerators of
-.B smallover
-fractions
-will be shifted up by at least this amount.
-This is usually less than sup1.
-.TP
-.B sup3
-Superscripts within denominators or square roots
-or subscripts or lower limits will be shifted up by at least
-this amount.
-This is usually less than sup2.
-.TP
-.B sub1
-Subscripts will normally be shifted down by at least this amount.
-.TP
-.B sub2
-When there is both a subscript and a superscript, the subscript
-will be shifted down by at least this amount.
-.TP
-.B sup_drop
-The baseline of a superscript will be no more
-than this much amount below the top of the object on
-which the superscript is set.
-.TP
-.B sub_drop
-The baseline of a subscript will be at least this much below
-the bottom of the object on which the subscript is set.
-.TP
-.B big_op_spacing1
-The baseline of an upper limit will be at least this
-much above the top of the object on which the limit is set.
-.TP
-.B big_op_spacing2
-The baseline of a lower limit will be at least this
-much below the bottom of the object on which the limit is set.
-.TP
-.B big_op_spacing3
-The bottom of an upper limit will be at least this much above the
-top of the object on which the limit is set.
-.TP
-.B big_op_spacing4
-The top of a lower limit will be at least this much below
-the bottom of the object on which the limit is set.
-.TP
-.B big_op_spacing5
-This much vertical space will be added above and below limits.
-.TP
-.B baseline_sep
-The baselines of the rows in a pile or matrix will normally be
-this far apart.
-In most cases this should be equal to the sum of
-.B num1
-and
-.BR denom1 .
-.TP
-.B shift_down
-The midpoint between the top baseline and the bottom baseline
-in a matrix or pile will be shifted down by this much from the axis.
-In most cases this should be equal to
-.BR axis_height .
-.TP
-.B column_sep
-This much space will be added between columns in a matrix.
-.TP
-.B matrix_side_sep
-This much space will be added at each side of a matrix.
-.TP
-.B draw_lines
-If this is non-zero, lines will be drawn using the
-.B \eD
-escape sequence, rather than with the
-.B \el
-escape sequence and the
-.B \e(ru
-character.
-.TP
-.B body_height
-The amount by which the height of the equation exceeds this
-will be added as extra space before the line containing the equation
-(using
-.BR \ex .)
-The default value is 85.
-.TP
-.B body_depth
-The amount by which the depth of the equation exceeds this
-will be added as extra space after the line containing the equation
-(using
-.BR \ex .)
-The default value is 35.
-.TP
-.B nroff
-If this is non-zero,
-then
-.B ndefine
-will behave like
-.B define
-and
-.B tdefine
-will be ignored,
-otherwise
-.B tdefine
-will behave like
-.B define
-and
-.B ndefine
-will be ignored.
-The default value is 0
-(This is typically changed to 1 by the
-.B eqnrc
-file for the
-.BR ascii ,
-.BR latin1 ,
-.BR utf8 ,
-and
-.B cp1047
-devices.)

-.RE
-.SS Macros
-Macros can take arguments.
-In a macro body,
-.BI $ n
-where
-.I n
-is between 1 and 9,
-will be replaced by the
-.IR n-th
-argument if the macro is called with arguments;
-if there are fewer than
-.I n
-arguments, it will be replaced by nothing.
-A word containing a left parenthesis where the part of the word
-before the left parenthesis has been defined using the
-.B define
-command
-will be recognized as a macro call with arguments;
-characters following the left parenthesis
-up to a matching right parenthesis will be treated as comma-separated
-arguments;
-commas inside nested parentheses do not terminate an argument.
-.TP
-.BI sdefine\  name\ X\ anything\ X
-This is like the
-.B define
-command, but
-.I name
-will not be recognized if called with arguments.
-.TP
-.BI include\ \(ts file \(ts
-Include the contents of

-.I X
-can be any character not appearing in

-.SS Fonts
-.B eqn
-normally uses at least two fonts to set an equation:
-an italic font for letters,
-and a roman font for everything else.
-The existing
-.B gfont
-command
-changes the font that is used as the italic font.
-By default this is
-.BR I .
-The font that is used as the roman font can be changed
-using the new
-.B grfont
-command.
-.TP
-.BI grfont\  f
-Set the roman font to
-.IR f .
-.LP
-The
-.B italic
-primitive uses the current italic font set by
-.BR gfont ;
-the
-.B roman
-primitive uses the current roman font set by
-.BR grfont .
-There is also a new
-.B gbfont
-command, which changes the font used by the
-.B bold
-primitive.
-If you only use the
-.BR roman ,
-.B italic
-and
-.B bold
-primitives to changes fonts within an equation,
-you can change all the fonts used by your equations
-just by using
-.BR gfont ,
-.B grfont
-and
-.B gbfont
-commands.
-.LP
-You can control which characters are treated as letters
-(and therefore set in italics) by using the
-.B chartype
-command described above.
-A type of
-.B letter
-will cause a character to be set in italic type.
-A type of
-.B digit
-will cause a character to be set in roman type.
