     This document describes in extremely terse form the features
of  the  --mmee  macro  package for version seven NROFF/TROFF.  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, vv's (vertical line spaces),
etc.

     For a more casual  introduction  to  text  processing  using
NROFF, refer to the document _W_r_i_t_i_n_g _P_a_p_e_r_s _w_i_t_h _N_R_O_F_F _u_s_i_n_g _-_m_e_.

     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 TROFF; in NROFF font 8 is underlined unless the --rrbb33  flag  is
specified  to use "true bold" font (most versions of NROFF 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 "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:

    \f8


     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:

UUSSDD::2200--22                                     --mmee RReeffeerreennccee MMaannuuaall


    .nr pi 8n

and not

    .nr pi 8

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.

     Registers  and strings of the form $$_x may be used in expres-
sions but should not be changed.  Macros of the form  $$_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.

     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.

     On daisy wheel type printers in twelve pitch, the --rrxx11  flag
can  be stated to make lines default to one eighth inch (the nor-
mal spacing for a newline in twelve-pitch).  This is normally too
small  for easy readability, so the default is to space one sixth
inch.

     The --rrvv22 flag will indicates that this _i_s being output on  a
C/A/T  phototypesetter;  this changes the page offset and inserts
cut marks.

     This documentation was NROFF'ed on September  25,  2015  and
applies to version 2.29 of the -me macros.

11..  PPaarraaggrraapphhiinngg

     These  macros  are  used  to begin paragraphs.  The standard
paragraph macro is ..pppp; the others are all variants  to  be  used
for special purposes.

     The  first call to one of the paragraphing macros defined in
this section or the ..sshh macro (defined in the next session)  _i_n_i_-
_t_i_a_l_i_z_e_s  the  macro  processor.   After initialization it is not
possible to use any of the following requests: ..sscc, ..lloo, ..tthh,  or
..aacc.   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.

..llpp            Begin  left-justified  paragraph.   Centering  and
               underlining  are  turned  off if they were on, the










--mmee RReeffeerreennccee MMaannuuaall                                     UUSSDD::2200--33


               font is set to \\nn((ppff [1] the type size is  set  to
               \\nn((pppp  [10p], and a \\nn((ppss space is inserted before
               the paragraph [0.35v in TROFF, 1v or 0.5v in NROFF
               depending  on  device  resolution].  The indent is
               reset to \\nn(($$ii [0] plus \\nn((ppoo [0] unless the para-
               graph  is  inside a display.  (see ..bbaa).  At least
               the first two lines  of  the  paragraph  are  kept
               together on a page.

..pppp            Like  ..llpp, except that it puts \\nn((ppii [5n] units of
               indent.  This is the standard paragraph macro.

..iipp_ _T_ _I        Indented paragraph with hanging tag.  The body  of
               the  following  paragraph is indented _I spaces (or
               \\nn((iiii [5n] spaces if _I is not specified) more than
               a  non-indented  paragraph  (such as with ..pppp) is.
               The title _T is exdented  (opposite  of  indented).
               The  result  is a paragraph with an even left edge
               and _T printed in the margin.  Any spaces in _T must
               be  unpaddable.   If  _T  will not fit in the space
               provided, ..iipp will start a new line.

..nnpp            A variant of .ip which numbers  paragraphs.   Num-
               bering  is  reset  after  a ..llpp, ..pppp, or ..sshh.  The
               current paragraph number is in \\nn(($$pp.

..bbuu            Like ..nnpp except that paragraphs  are  marked  with
               bullets  (+o).  Leading space is eliminated to cre-
               ate compact lists.

22..  SSeeccttiioonn HHeeaaddiinnggss

     Numbered sections are similar to paragraphs  except  that  a
section number is automatically generated for each one.  The sec-
tion numbers are of the form 11..22..33.  The _d_e_p_t_h of the section  is
the count of numbers (separated by decimal points) in the section
number.

     Unnumbered section headings are similar, except that no num-
ber is attached to the heading.

..sshh_ _+_N_ _T_ _a_ _b_ _c _dBe_egi_fn  numbered section of depth _N.  If _N is miss-
               ing the current depth (maintained  in  the  number
               register  \\nn(($$00) is used.  The values of the indi-
               vidual parts of the section number are  maintained
               in  \\nn(($$11  through  \\nn(($$66.   There is a \\nn((ssss [1v]
               space before the section.  _T is printed as a  sec-
               tion title in font \\nn((ssff [8] and size \\nn((sspp [10p].
               The "name" of the  section  may  be  accessed  via
               \\**(($$nn.   If  \\nn((ssii is non-zero, the base indent is
               set to \\nn((ssii times the section depth, and the sec-
               tion  title  is  exdented.   (See  ..bbaa.)  Also, an
               additional indent of \\nn((ssoo [0]  is  added  to  the










UUSSDD::2200--44                                     --mmee RReeffeerreennccee MMaannuuaall


               section  title  (but  not  to the body of the sec-
               tion).  The font is  then  set  to  the  paragraph
               font,  so  that  more information may occur on the
               line with  the  section  number  and  title.   ..sshh
               insures  that  there  is  enough room to print the
               section head plus the  beginning  of  a  paragraph
               (about  3 lines total).  If _a through _f are speci-
               fied, the section number is  set  to  that  number
               rather  than incremented automatically.  If any of
               _a through _f are a hyphen that number is not reset.
               If _T is a single underscore ("_") 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.

..ssxx_ _+_N         Go  to  section depth _N [--11], but do not print the
               number and title, and do not increment the section
               number  at level _N.  This has the effect of start-
               ing a new paragraph at level _N.

..uuhh_ _T          Unnumbered  section  heading.   The  title  _T   is
               printed  with  the  same  rules for spacing, font,
               etc., as for ..sshh.

..$$pp_ _T_ _B_ _N      Print section heading.  May be  redefined  to  get
               fancier  headings.   _T  is the title passed on the
               ..sshh or ..uuhh line; _B is the section number for  this
               section,  and  _N  is  the  depth  of this section.
               These parameters are not always present;  in  par-
               ticular, ..sshh passes all three, ..uuhh passes only the
               first, and ..ssxx passes three, but the first two are
               null  strings.  Care should be taken if this macro
               is redefined; it is quite complex and subtle.

..$$00_ _T_ _B_ _N      This macro is  called  automatically  after  every
               call to ..$$pp.  It is normally undefined, but may be
               used to automatically put every section title into
               the  table  of  contents or for some similar func-
               tion.  _T is the  section  title  for  the  section
               title  which  was  just  printed, _B is the section
               number, and _N is the section depth.

..$$11_ -_ ..$$66      Traps called just before printing that depth  sec-
               tion.   May be defined to (for example) give vari-
               able spacing before sections.   These  macros  are
               called from ..$$pp, so if you redefine that macro you
               may lose this feature.

33..  HHeeaaddeerrss aanndd FFooootteerrss

     Headers and footers are put at the top and bottom  of  every
page  automatically.   They  are  set  in font \\nn((ttff [3] and size










--mmee RReeffeerreennccee MMaannuuaall                                     UUSSDD::2200--55


\\nn((ttpp [10p].  Each of the definitions apply as of the _n_e_x_t  page.
Three-part titles must be quoted if there are two blanks adjacent
anywhere in the title or more than eight blanks total.

     The spacing of headers and footers are controlled  by  three
number registers.  \\nn((hhmm [4v] is the distance from the top of the
page to the top of the header, \\nn((ffmm [3v] is  the  distance  from
the bottom of the page to the bottom of the footer, \\nn((ttmm [7v] is
the distance from the top of the page to the top of the text, and
\\nn((bbmm  [6v]  is  the  distance from the bottom of the page to the
bottom of the text (nominal).  The macros ..mm11, ..mm22, ..mm33, and  ..mm44
are also supplied for compatibility with ROFF documents.

..hhee_ _'_l_'_m_'_r_'    Define three-part header, to be printed on the top
               of every page.

..ffoo_ _'_l_'_m_'_r_'    Define footer, to be  printed  at  the  bottom  of
               every page.

..eehh_ _'_l_'_m_'_r_'    Define  header,  to be printed at the top of every
               even-numbered page.

..oohh_ _'_l_'_m_'_r_'    Define header, to be printed at the top  of  every
               odd-numbered page.

..eeff_ _'_l_'_m_'_r_'    Define  footer,  to  be  printed  at the bottom of
               every even-numbered page.

..ooff_ _'_l_'_m_'_r_'    Define footer, to be  printed  at  the  bottom  of
               every odd-numbered page.

..hhxx            Suppress headers and footers on the next page.

..mm11_ _+_N         Set  the space between the top of the page and the
               header [4v].

..mm22_ _+_N         Set the space between the  header  and  the  first
               line of text [2v].

..mm33_ _+_N         Set  the  space between the bottom of the text and
               the footer [2v].

..mm44_ _+_N         Set the space between the footer and the bottom of
               the page [4v].

..eepp            End  this  page,  but  do not begin the next page.
               Useful for forcing out footnotes, but  other  than
               that hardly every used.  Must be followed by a ..bbpp
               or the end of input.

..$$hh            Called at every page to print the header.  May  be
               redefined  to  provide  fancy  (e.g.,  multi-line)
               headers, but doing so loses the  function  of  the










UUSSDD::2200--66                                     --mmee RReeffeerreennccee MMaannuuaall


               ..hhee, ..ffoo, ..eehh, ..oohh, ..eeff, and ..ooff requests, as well
               as the chapter-style title feature of ..++cc.

..$$ff            Print footer; same comments apply as in ..$$hh.

..$$HH            A normally undefined macro which is called 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  col-
               umn headings and the like.

44..  DDiissppllaayyss

     All  displays  except  centered  blocks and block quotes are
preceded and followed by an extra \\nn((bbss [same  as  \\nn((ppss]  space.
Quote  spacing  is stored in a separate register; centered blocks
have no default initial or trailing space.  The vertical  spacing
of  all  displays  except quotes and centered blocks is stored in
register \\nn(($$RR instead of \\nn(($$rr.

..((ll_ _m_ _f        Begin list.  Lists  are  single  spaced,  unfilled
               text.   If  _f is FF, the list will be filled.  If _m
               [II] is II the list is indented by \\nn((bbii [4m]; if  MM
               the  list is indented to the left margin; if LL the
               list is left justified with respect  to  the  text

               in \\nn(($$ii and set with ..bbaa) is not zero); and if  CC
               the list is centered on a line-by-line basis.  The

               a  ..))ll.  This macro is almost like ..((bb except that

               page.

..))ll            End list.

..((qq            Begin  major  quote.   These  are  single  spaced,

               text of a keep is kept together  on  one  page  if
               possible  (keeps are useful for tables and figures
               which should not be broken over a page).   If  the

               changes to "underline font"  (usually  italics  in

               is safe in nofill mode only.

               TROFF uses directed quotes.

               is safe in nofill mode only.

               and pasted in later.  To get a partial-page paste-
               in display, say ..ssvv _N, where _N is  the  amount  of
               space  to leave; this space will be output immedi-

               should all be of the form ..**_X, where _X is any let-
               ter (upper or lower case) or digit.

..ttpp            Begin  title page.  Spacing at the top of the page
               can occur, and headers and footers are suppressed.
               Also,  the page number is not incremented for this
               page.

..tthh            Set thesis mode.  This defines the  modes  accept-
               able  for a doctoral dissertation at Berkeley.  It
               double spaces, defines the header to be  a  single
               page  number,  and  changes  the margins to be 1.5
               inch on the left and one inch on the top.  ..++++ and
               ..++cc  should  be  used with it.  This macro must be
               stated before initialization, that is, before  the
               first call of a paragraphing macro or ..sshh.

..++++_ _m_ _H        This  request  defines  the  section  of the paper
               which  we  are  entering.   The  section  type  is
               defined  by  _m.   CC means that we are entering the
               chapter portion of the paper, AA means that we  are
               entering  the  appendix  portion  of  the paper, PP
               means that the material following  should  be  the
               preliminary  portion (abstract, table of contents,
               etc.)  portion of the paper, AABB means that we  are
               entering the abstract (numbered independently from
               1 in Arabic numerals), and BB  means  that  we  are
               entering  the  bibliographic portion at the end of
               the paper.  Also,  the  variants  RRCC  and  RRAA  are
               allowed,  which  specify renumbering of pages from
               one at the beginning of each chapter or  appendix,
               respectively.   The  _H  parameter  defines the new
               header.  If there are any spaces in it, the entire
               header  must be quoted.  If you want the header to
               have the chapter number  in  it,  Use  the  string
               \\\\\\\\nn((cchh.   For  example, to number appendixes AA..11
               etc., type ..++++ RRAA  ''''''\\\\\\\\nn((cchh..%%''.   Each  section
               (chapter,  appendix,  etc.)  should be preceded by
               the ..++cc request.  It should be mentioned  that  it
               is  easier when using TROFF to put the front mate-
               rial at the end of the paper, so that the table of
               contents  can be collected and put out; this mate-
               rial can then be physically moved to the beginning
               of the paper.

..++cc_ _T          Begin chapter with title _T.  The chapter number is
               maintained in \\nn((cchh.  This register is incremented
               every  time  ..++cc  is called with a parameter.  The










--mmee RReeffeerreennccee MMaannuuaall                                    UUSSDD::2200--1133


               title and chapter number are printed by ..$$cc.   The
               header is moved to the footer on the first page of
               each chapter.  If _T is omitted, ..$$cc is not called;
               this  is useful for doing your own "title page" at
               the beginning  of  papers  without  a  title  page
               proper.   ..$$cc  calls ..$$CC as a hook so that chapter
               titles can be inserted into a  table  of  contents
               automatically.  The footnote numbering is reset to
               one.

..$$cc_ _T          Print chapter number (from  \\nn((cchh)  and  _T.   This
               macro  can  be  redefined  to  your liking.  It is
               defined by default to be acceptable for a PhD the-
               sis  at  Berkeley.  This macro calls $$CC, which can
               be defined to make index entries, or whatever.

..$$CC_ _K_ _N_ _T      This macro is called by ..$$cc.  It is normally unde-
               fined,  but  can  be  used to automatically insert
               index entries,  or  whatever.   _K  is  a  keyword,
               either  "Chapter"  or "Appendix" (depending on the
               ..++++ mode); _N is the chapter  or  appendix  number,
               and _T is the chapter or appendix title.

..aacc_ _A_ _N        This  macro  (short  for  ..aaccmm)  sets up the NROFF
               environment for camera-ready papers as used by the
               ACM.   This format is 25% larger, and has no head-
               ers or footers.  The author's name _A is printed at
               the  bottom  of  the  page (but off the part which
               will be printed in  the  conference  proceedings),
               together  with  the  current  page  number and the
               total number of pages _N.  Additionally, this macro
               loads the file //uussrr//lliibb//mmee//aaccmm..mmee, which may later
               be augmented with other macros useful for printing
               papers  for  ACM  conferences.  It should be noted
               that this macro will not work correctly in version
               7  TROFF, since it sets the page length wider than
               the physical width of  the  C/A/T  phototypesetter
               roll.

     There are a number of  special  characters  and  diacritical
marks  (such  as  accents)  available  through -me.  To reference
these characters, you must call the macro ..sscc to define the char-
acters before using them.

..sscc            Define  special  characters and diacritical marks,
               as described in the  remainder  of  this  section.
               This  macro  must be stated before initialization.

     I  would like to thank Bob Epstein, Bill Joy, and Larry Rowe
for having the courage to use the -me macros to produce non-triv-
ial  papers  during  the  development  stages; Ricki Blau, Pamela
Humphrey, and Jim Joyce for their  help  with  the  documentation
phase; peter kessler for numerous complaints, most accompanied by
fixes; and the plethora of people who have contributed ideas  and
have given support for the project.

SSuummmmaarryy

     This  alphabetical  list summarizes all macros, strings, and
number registers available in the  -me  macros.   Selected  _t_r_o_f_f
commands,  registers,  and  functions are included as well; those
listed can generally be used with impunity.

     The columns are the name of the command, macro, register, or
string; the type of the object, and the description.  Types are MM
for macro or builtin command (invoked with ..  or '' in  the  first
input  column),  SS for a string (invoked with \\** or \\**((), RR for a
number register (invoked with \\nn or  \\nn((),  and  FF  for  a  _t_r_o_f_f
builtin  function  (invoked  by  preceding it with a single back-
slash).

     Lines marked with  are _t_r_o_f_f internal codes.   Lines  marked
with   or  may  be  defined by the user to get special functions;
indicates that these are defined by default and changing them may
have  unexpected side effects.  Lines marked with are specific to
_d_i_t_r_o_f_f (device-independent _t_r_o_f_f).
