+This document describes
+in extremely terse form
+the features
+of the
+.b \-me
+macro package
+for version seven \*N/\*T\*(dg.
+.(f
+\(dg\*N and \*T may be trademarks of AT&T Bell Laboratories.
+.)f
+Some familiarity is assumed
+with
+those programs.
+Specifically,
+the reader should understand
+breaks,
+fonts,
+pointsizes,
+the use and definition of number registers
+and strings,
+how to define macros,
+and scaling factors for ens, points,
+.b v 's
+(vertical line spaces),
+etc.
+.pp
+For a more casual introduction
+to text processing
+using \*N,
+refer to the document
+.ul
+Writing Papers with \*N using \-me.
+.pp
+There are a number of macro parameters
+that may be adjusted.
+Fonts may be set to a font number only.
+Font 8 means bold font in \*T;
+in \*N font 8
+is underlined
+unless the
+.b \-rb3
+flag is specified to use
+.q "true bold"
+font
+(most versions of \*N do not interpret bold font nicely).
+Font 0 is no font change;
+the font of the surrounding text
+is used instead.
+Notice that fonts 0 and 8 are
+.q pseudo-fonts ;
+that is,
+they are simulated by the macros.
+This means that although it is legal to set a font register
+to zero or eight,
+it is not legal to use the escape character form,
+such as:
+.(b
+\ef8
+.)b
+.pp
+All distances
+are in basic units,
+so it is nearly always necessary
+to use a scaling factor.
+For example,
+the request
+to set the paragraph indent
+to eight one-en spaces is:
+.(b
+\&.nr pi 8n
+.)b
+and not
+.(b
+\&.nr pi 8
+.)b
+which would set the paragraph indent to eight basic units,
+or about 0.02 inch.
+Default parameter values are given in brackets
+in the remainder of this document.
+.pp
+Registers and strings
+of the form
+.b $ \c
+.i x
+may be used in expressions
+but should not be changed.
+Macros of the form
+.b $ \c
+.i x
+perform some function
+(as described)
+and may be redefined
+to change this function.
+This may be a sensitive operation;
+look at the body of the original macro
+before changing it.
+.pp
+All names in \-me
+follow a rigid naming convention.
+The user may define number registers,
+strings,
+and macros,
+provided that s/he
+uses single character upper case names
+or double character names
+consisting of letters and digits,
+with at least one upper case letter.
+In no case should special characters
+be used in user-defined names.
+.pp
+On daisy wheel type printers
+in twelve pitch,
+the
+.b \-rx1
+flag can be stated to make lines default to
+one eighth inch
+(the normal spacing for a newline in twelve-pitch).
+This is normally too small for easy readability,
+so the default is to space one sixth inch.
+.pp
+The
+.b \-rv2
+flag will indicates that this
+.i is
+being output on a C/A/T
+phototypesetter;
+this changes the page offset
+and inserts cut marks.
+.pp
+This documentation was
+.if n \*N'ed
+.if t \*T'ed
+on \*(td
+and applies to version
+\*(MO
+of the \-me macros.
+.sh 1 "Paragraphing"
+.pp
+These macros are used
+to begin paragraphs.
+The standard paragraph macro
+is
+.b .pp ;
+the others are all variants
+to be used for special purposes.
+.pp
+The first call to one of the paragraphing macros
+defined in this section
+or the
+.b .sh
+macro
+(defined in the next session)
+.i initializes
+the macro processor.
+After initialization
+it is not possible to use any of the following requests:
+.b .sc ,
+.b .lo ,
+.b .th ,
+or
+.b .ac .
+Also,
+the effects of changing parameters
+which will have a global effect
+on the format of the page
+(notably page length and header and footer margins)
+are not well defined
+and should be avoided.
+.TL
+.b .lp
+.DE
+Begin left-justified paragraph.
+Centering and underlining
+are turned off if they were on,
+the font is set to
+.NR (pf
+[1]
+the type size
+is set to
+.NR (pp
+[10p],
+and a
+.NR (ps
+space is inserted
+before the paragraph
+[0.35v in \*T, 1v or 0.5v in \*N
+depending on device resolution].
+The indent is reset
+to
+.NR ($i
+[0]
+plus
+.NR (po
+[0]
+unless the paragraph
+is inside a display.
+(see
+.b .ba ).
+At least
+the first two lines
+of the paragraph
+are kept together
+on a page.
+.TL
+.b .pp
+.DE
+Like
+.b .lp ,
+except that it puts
+.NR (pi
+[5n]
+units of indent.
+This is the standard paragraph macro.
+.TL
+.b .ip
+.i T
+.i I
+.DE
+Indented paragraph
+with hanging tag.
+The body of the following paragraph
+is indented
+.i I
+spaces
+(or
+.NR (ii
+[5n]
+spaces
+if
+.i I
+is not specified)
+more than a non-indented paragraph
+(such as with
+.b .pp )
+is.
+The title
+.i T
+is exdented (opposite of indented).
+The result is a paragraph
+with an even left edge
+and
+.i T
+printed in the margin.
+Any spaces in
+.i T
+must be unpaddable.
+If
+.i T
+will not fit in the space provided,
+.b .ip
+will start a new line.
+.TL
+.b .np
+.DE
+A variant of .ip which numbers paragraphs.
+Numbering is reset
+after a
+.b .lp ,
+.b .pp ,
+or
+.b .sh .
+The current paragraph number
+is in
+.NR ($p .
+.TL
+.b .bu
+.DE
+Like
+.b .np
+except that paragraphs are marked with bullets (\(bu).
+Leading space is eliminated to create compact lists.
+.sh 1 "Section Headings"
+.pp
+Numbered sections
+are similar to paragraphs
+except that a
+section number
+is automatically
+generated for each one.
+The section numbers are of the form
+.b 1.2.3 .
+The
+.i depth
+of the section
+is the count of numbers
+(separated by decimal points)
+in the section number.
+.pp
+Unnumbered section headings are similar,
+except that no number is attached
+to the heading.
+.TL
+.b .sh
+.i +N
+.i T
+.i "a b c d e f"
+.DE
+Begin numbered section
+of depth
+.i N .
+If
+.i N
+is missing
+the current depth
+(maintained in
+the number register
+.NR ($0 )
+is used.
+The values of
+the individual parts of the section number
+are maintained in
+.NR ($1
+through
+.NR ($6 .
+There is a
+.NR (ss
+[1v]
+space before the section.
+.i T
+is printed
+as a section title
+in font
+.NR (sf
+[8]
+and size
+.NR (sp
+[10p].
+The
+.q name
+of the section may be accessed via
+.ST ($n .
+If
+.NR (si
+is non-zero,
+the base indent
+is set to
+.NR (si
+times the section depth,
+and the section title
+is exdented.
+(See
+.b .ba .)
+Also,
+an additional indent of
+.NR (so
+[0]
+is added to the section title
+(but not to the body of the section).
+The font is then set
+to the paragraph font,
+so that more information may occur
+on the line
+with the section number
+and title.
+.b .sh
+insures that there is enough room
+to print the section head
+plus the beginning of a paragraph
+(about 3 lines total).
+If
+.i a
+through
+.i f
+are specified,
+the section number is set to that number
+rather than incremented automatically.
+If any of
+.i a
+through
+.i f
+are a hyphen
+that number is not reset.
+If
+.i T
+is a single underscore
+(\c
+.q _ )
+then the section depth and numbering is reset,
+but the base indent is not reset
+and nothing is printed out.
+This is useful to automatically
+coordinate section numbers with
+chapter numbers.
+.TL
+.b .sx
+.i +N
+.DE
+Go to section depth
+.i N
+[\c
+.b \-1 ],
+but do not print the number
+and title,
+and do not increment the section number
+at level
+.i N .
+This has the effect
+of starting a new paragraph
+at level
+.i N .
+.TL
+.b .uh
+.i T
+.DE
+Unnumbered section heading.
+The title
+.i T
+is printed
+with the same rules for spacing,
+font, etc.,
+as for
+.b .sh .
+.TL
+.b .$p
+.i T
+.i B
+.i N
+.DE
+Print section heading.
+May be redefined
+to get fancier headings.
+.i T
+is the title passed on the
+.b .sh
+or
+.b .uh
+line;
+.i B
+is the section number for this section,
+and
+.i N
+is the depth of this section.
+These parameters are not always present;
+in particular,
+.b .sh
+passes all three,
+.b .uh
+passes only the first,
+and
+.b .sx
+passes three,
+but the first two
+are null strings.
+Care should be taken if this macro
+is redefined;
+it is quite complex and subtle.
+.TL
+.b .$0
+.i T
+.i B
+.i N
+.DE
+This macro is called automatically
+after every call to
+.b .$p .
+It is normally undefined,
+but may be used
+to automatically put
+every section title
+into the table of contents
+or for some similar function.
+.i T
+is the section title
+for the section title which was just printed,
+.i B
+is the section number,
+and
+.i N
+is the section depth.
+.TL
+.b .$1
+\-
+.b .$6
+.DE
+Traps called just before printing that depth section.
+May be defined to
+(for example)
+give variable spacing
+before sections.
+These macros are called from
+.b .$p ,
+so if you redefine that macro
+you may lose this feature.
+.sh 1 "Headers and Footers"
+.ds TP \fI\(aal\|\(aam\^\(aar\^\(aa\fP
+.pp
+Headers and footers
+are put at the top and bottom
+of every page
+automatically.
+They are set in font
+.NR (tf
+[3]
+and size
+.NR (tp
+[10p].
+Each of the definitions
+apply as of the
+.i next
+page.
+Three-part titles
+must be quoted
+if there are two blanks adjacent
+anywhere in the title
+or more than eight blanks total.
+.pp
+The spacing
+of headers and footers
+are controlled by three number registers.
+.NR (hm
+[4v]
+is the distance from the top of the page
+to the top of the header,
+.NR (fm
+[3v]
+is the distance from the bottom of the page
+to the bottom of the footer,
+.NR (tm
+[7v]
+is the distance from the top of the page
+to the top of the text,
+and
+.NR (bm
+[6v]
+is the distance from the bottom of the page
+to the bottom of the text
+(nominal).
+The macros
+.b .m1 ,
+.b .m2 ,
+.b .m3 ,
+and
+.b .m4
+are also supplied for compatibility
+with
+\s-1ROFF\s0 documents.

+.DE
+Called at every page

+(e.g.,
+multi-line)
+headers,
+but doing so
+loses the function of the
+.b .he ,
+.b .fo ,

+.TL
+.b .$H
+.DE
+A normally undefined macro

+at the top of each page
+(after putting out
+the header,
+initial saved floating keeps,
+etc.);
+in other words,
+this macro is called immediately before
+printing text
+on a page.
+It can be used for column headings
