\# Inasmuch as possible, macros that turn a feature on or off follow
\# a similar style.  Invoking the macro without an argument turns
\# the feature on.  Invoking it with any other argument turns it off.
\# Use of the argument OFF is recommended, but not required; users
\# may find other conventions preferable (e.g. NO, X, END, QUIT, etc.).
\#
\# "<anything>" in the description of arguments that can be passed
\# to a macro means that any argument turns the feature off.

\# +++PAGE LAYOUT+++
\#
\# Macros that control the physical layout of the page: paper size
\# and margins.
\#
\# PAGE WIDTH
\# ----------
\# *Argument:
\#   <width of printer sheet (ipPc)>
\# *Function:
\#   Stores user supplied page width in register #PAGE_WIDTH.
\# *Notes:
\#   #PAGE_WIDTH is used to establish the default LL (and right margin).
\#   Requires unit of measure.

\# --------
\# *Argument:
\#   <offset from page left (ipPc)>

\# --------
\# *Argument:
\#   <width of right margin (ipPc)>
\# *Function:
\#   Stores user supplied right margin in register #R_MARGIN.
\# *Notes:
\#   This is a pseudo-margin.  Right margin is actually a function of
\#   line length.  The macro calculates line length from the page offset
\#   and the value plugged into #R_MARGIN.
\#
\#   N.B. -- PAGEWIDTH and L_MARGIN have to be defined before R_MARGIN.

\#
\# POINT SIZE
\# ----------
\# *Arguments:
\#   <point size of type>
\# *Function:
\#   Sets point size to user supplied value in scaled points.
\#   If #AUTO_LEAD is on, sets .vs to #AUTOLEAD_VALUE+#PT_SIZE.
\# *Notes:
\#   Must NOT use a unit of measure.
\#

\# -------
\# *Argument:
\#   <leading between lines of text>

\# --------
\# *Argument:
\#   <leading value to add to #PT_SIZE> [FACTOR]
\# *Function:
\#   Stores user supplied auto-lead value in register #AUTOLEAD_VALUE.
\#   Adds #AUT0LEAD_VALUE to #PT_SIZE when invoked to set leading.
\#   All subsequent PT_SIZE requests reset the leading in the same way until
\#   AUTOLEAD is turned off.
\# *Notes:
\#   With the optional FACTOR argument, the current point size is
\#   multiplied by #AUTOLEAD_VALUE instead of the two being added
\#   together.

\#
\# INLINE KERNING AND HORIZONTAL MOVEMENT
\# --------------------------------------
\# *Kerning
\#  Inline kerning provides a simple method for users to adjust the
\#  amount of space between any two letters.  It's predicated on a
\#  unit of measure "U", which is 1/36 of the current point size as
\#  returned by \n[.ps].  E.g., if the current point size is 18,
\#  \n[.ps] returns 18000u, therefore U=500u.  Since U remains
\#  proportional relative to the current point size, the amount
\#  of kerning between two letters as expressed in Us remains
\#  visually similar regardless of changes in point size.
\#
\#  N.B.--the amount of inline kerning supplied by \*[BU#] or
\#  \*[FU#] is added to or subtracted from any kerning that already
\#  takes place between two characters when automatic kerning is
\#  turned on.
\#
\#  In groff v. 1.17.2, it was not possible to pass arguments to macros that
\#  were executed with inline escapes, nor thence to evaluate conditional
\#  expressions.  Consequently, each pseudo-escape \[BU#] had to be defined
\#  separately with ".char".
\#
\#  As of v. 1.18, one can pass arguments to inline strings/macros,
\#  hence it is now possible to do \*[BU #] where #, inline, is the desired
\#  number of kern units.  The original .char definitions have been left in
\#  for backward compatibility with documents created prior to mom-1.1.3c.

\# WHOLE LINE KERNING (RW and EW)
\# -----------------------------
\# The line kerning macros are special instances of track kerning,
\# used where a complete line needs to be tightened (or relaxed) in
\# order to accomodate or remove one or two more characters
\# than the default justification permits.
\#
\# *Argument:
\#   <amount of overall "kerning" (letter spacing) to apply to the line>
\# *Function:
\#   Invokes .tkf (track kerning) for the current font with
\#   1 as both the upper and lower point size limits, so that
\#   the value entered by the user applies regardless of point
\#   size.  RW ("Reduce Whitespace") reduces the amount of space
\#   between all characters by an equal amount.  EW ("Extra
\#   Whitespace") increases the amount of space.
\# *Notes:
\#   Decimal values are acceptable.
\#
\#   The groff documentation is a tad confusing about what unit of
\#   measure is used in track kerning, only that the width of each
\#   character is increased or decreased by the amount(s) passed as
\#   arguments to .tkf, and something about linear function of point
\#   size.  In fact, with the way I've put this macro together, it
\#   doesn't matter.  All the user needs to know is that a value
\#   of one will produce an unacceptably tight or loose line at most
\#   text point sizes; therefore, effective use of RW and EW is in
\#   the fractional range below 1 (e.g. .25, .5).  Given that RW
\#   and EW are for massaging type, a certain amount of
\#   experimentation and previewing is expected and necessary.
\#
\#   \n(.f holds the current font number, which is acceptable to .tkf.
\#
\#   RW and EW must be reset to 0 to cancel their effect on
\#   subsequent output lines.
\#

\# ------------------
\# *Arguments:

\# *Function:

\# *Notes:
\#   Mostly, users will want .br's before any kind of line kerning, but
\#   there may be cases where they don't.  BR_BEFORE_LINE_KERN is off by
\#   default and must be invoked explicitly.

\# ----------------
\# *Arguments:
\#   <none> | <anything> | DEFAULT
\#                 or
\#   LINES <#> | MARGIN <#> | SPACE <#>
\# *Function:
\#   Turns auto hyphenation on or off, resets the hyphenation style
\#   to default, or permits the setting of various hyphenation
\#   parameters.
\# *Notes:
\#   HY ON defaults to .hy 14, i.e. no hyphens after the
\#   first two or before the last two characters of a word, and
\#   no hyphenation of the last line prior to a trap (e.g.,
\#   at the bottom of a page).
\#
\#   HY DEFAULT resets the hyphenation style to .hy 14 (see
\#   above) if that behaviour is desired after changes have been
\#   made to LINES, MARGIN, or SPACE.
\#
\#   HY LINES <#> sets the number of allowable consecutive hyphenated lines.
\#
\#   HY MARGIN <#> sets the amount of space (ipPcm) allowed at the end
\#   of a line in QUAD mode before hyphenation is tripped (e.g. if there's
\#   only 6 points left, groff won't try to hyphenate the next word).
\#
\#   HY SPACE sets the amount of extra interword space (ipPcm) that can
\#   be added in JUSTIFY mode to prevent a line from being hyphenated.

\# LEFT, RIGHT, AND CENTER

\# The purpose of these macros is to allow the user to enter lines

\# enter .BR or .br between lines.  For the sake of consistency,
\# all three appear to behave similarly (from the point of view of the user),

\# RIGHT, and CENTER must be followed by .QUAD [L R C J] or .JUSTIFY
\# to restore text to groff fill mode.

\# *Function:

\# +++TABS+++
\#
\#   There are two different kinds of tabs available: typesetting tabs
\#   and string tabs.
\#
\#   Typesetting tabs are set with TAB_SET, which requires a tab number,
\#   an indent (offset) from the left margin and a length (optionally
\#   with a quad direction and an instruction to fill lines).  After tabs
\#   are set with TS, they are called with .TAB <#>, where <#>
\#   corresponds to the number passed to TAB_SET as a valid tab number.
\#
\#   String tabs allow the user to mark off tab positions inline.  Tab
\#   indents and lengths are calculated from the beginning and end
\#   positions of the marks.  Up to 19 string tabs may be created,
\#   numbered 1-19.  Once created, they are called with .TAB <#>,
\#   just like typesetting tabs.
\#
\#   Setting up string tabs is a two-step procedure.  First, the user
\#   enters an input line in which s/he wants to mark off string tabs.
\#   The beginning of a tab is marked with \*[ST<#>], where <#> is
\#   the desired number of the tab.  The end of the the tab is marked
\#   with \*[ST<#>X].  All ST's must have a matching STX.  String tabs
\#   may be nested.
\#
\#   Next, the user invokes .ST <#> for every string tab defined, and
\#   optionally passes quad information to it.  That done, string tabs
\#   can be called just like typesetting tabs.
\#
\#   String tabs don't preview properly with gxditview.  Use gv instead.

\# QUAD AND SET STRING TABS
\# ------------------------
\# *Arguments:
\#   <stringtab number>  L | R | C | J  [QUAD]
\# *Function:
\#   Creates strings $ST<#>_QUAD_DIR and $ST<#>_FILL, then sets up a
\#   tab based on the collected information.
\# *Notes:
\#   Like TS, ST invoked without a quad direction will default to LEFT.
\#   If lines should be filled and quadded, use the optional argument QUAD.
\#   N.B. -- indents *must* be turned off before setting string tabs
\#   inside .PAD

\#
\# TAB SET
\# -------
\# *Arguments:
\#   <#>  ident(ipPcm)  length(ipPcm)  [L | R | C | J [QUAD]]
\# *Function:
\#   Creates macros TAB<#> and TAB <#>, where # is any arbitrary number.
\#   TAB# is a typesetting tab (i.e. a tab defined as an indent
\#   from the page left offset plus a line length.)
\# *Notes:
\#   <#>    = arbitrary digit to identify the tab
\#   indent = indent from left margin; unit of measure required
\#   length = length of tab (unit of measure required; can be
\#            \w'<string>'u--if more than one word in string, surround
\#            with double quotes "\w'<three word string>'"
\#   LRCJ   = quad for tab (left, right, center, justified)
\#            If option QUAD afterwards is not given, quad is line for line
\#            (no fill mode), meaning that there's no need for .BR or .br
\#            between lines.
\#   QUAD   = fill tab (so it behaves as if .QUAD LRC or .JUSTIFY
\#            had been given).
\#
\#   N.B. -- indents *must* be turned off before setting tabs
\#
\#   Examples:
\#
\#     .TAB_SET 1 2P+6p 12P C
\#
\#   means "create a tab numbered 1 that starts 2 picas and 6 points from
\#   the left margin, is 12 picas long, and centre each input line."
\#
\#     .TAB_SET 1 2P+6P 12P C QUAD
\#
\#   means exactly the same thing, except that input lines are joined and
\#   the area delimted by the tab filled with centered text.
\#
\#   TAB <#> can be called at any time after being set.
\#
\#   Tabs are NOT columnar in behaviour.  If the text inside a
\#   tab runs to several lines, when you call the next tab a break
\#   occurs, meaning that the new tab starts one line below the last
\#   line in the previous tab.  For columnar behaviour, you must
\#   use the multi-column macros in addition to tabs.
\#
\#   If you want tabs to line up bottom-line to bottom-line (most likely
\#   single line tabs), use .TN (provided the tabs are numbered sequentially).
\#   Otherwise, you must use .EL then .TAB # if you want them to align.
\#
\#   If you want to reset tabs, you must use .TQ before .TAB_SET.
\#
\#   Note that indents are turned off automatically whenever a new
\#   tab is called with TAB #.
\#
\#   Tabs themselves are user-invoked using the TAB macro with a numeric
\#   argument, e.g. TAB 1.
\#
\#   Generally, in order not to get confused, it's a good idea
\#   to make sure all indents are off before setting tabs.

\# UNDERSCORE
\# ----------
\# *Arguments:
\#   [points below baseline] "text"
\# *Function:
\#   Places an underscore 2 points under the string if no lead given,
\#   otherwise places underscore under string by user specified amount.
\# *Notes:
\#   When using this macro, the string to be underscored must begin
\#   with double-quotes ("), regardless of whether it's the sole
\#   argument or the second.
\#   E.g.:
\#      .UNDERSCORE "Text to be underscored
\#         or
\#      .UNDERSCORE 2p "Text to be underscored
\#
\#   All text is underscored (including punctuation and spaces).
\#   This is the primary difference between UNDERLINE and UNDERSCORE,
\#   aside from the fact the UNDERLINE only works with Courier.
\#
\#   UNDERSCORE does not work across line breaks.  Each line of
\#   text must be entered separately with UNDERSCORE.  If the
\#   UNDERSCORE begins in the middle of a line and crosses over a
\#   break, the portion before the break must be entered in its own
\#   UNDERSCORE, as must the portion that comes after the break.

\# *Notes:
\#   CONDENSE_OR_EXTEND is invoked from the aliases
\#   CONDENSE and EXTEND.  CONDENSE implies <100, EXTEND
\#   implies >100.  Do not use a percent sign in the argument.

\#   Advances and prints dropcap; reverses and prints indented text
\#   to bottom of dropcap, then resets indent to left margin (plus
\#   any indent that was in effect prior to invoking DROPCAP).
\# *Notes:
\#   Drop caps put a strain on on resource-challenged systems.
\#
\#   Drop caps when using the doc processing macro PP only work with

\#   is TYPESET.  If these conditions aren't met, DROPCAPS is silently

\#

\#
\# +++INDENTS+++
\#
\# There are five styles of indents: left, right, both, temporary,
\# and hanging.  Each is set/invoked with a different macro.
\# Indent macros begin with the letter "I", hence .IL means "indent left,"
\# .IR means "indent right," and so on.
\#
\# The first time any of the indent macros is used, it requires an
\# argument--the size of the indent in ipPcm.  The size may also
\# be entered using the \w'#' function--very useful for numbered
\# lists using HI).  The unit of measure is required.  Subsequent
\# invocations don't require the argument; the indent measure remains the
\# same until it's changed by invoking the macro with an argument again.
\#
\# If no indents are in effect, the arguments passed to indent macros are
\# measured from the left and right margins of the page.  If a left indent
\# or a right indent is already in effect, the arguments passed to
\# the indent macros are calculated from the current values; in other words,
\# the arguments are additive.  If you quit an indent and later return
\# to it, its value will be the value last in effect, unless you pass
\# it an argument.  If you do pass an argument, it is added to the last
\# value in effect, unless you cleared the indent with one of
\# .I<LRB>X macros.
\#
\# Example
\# -------
\#
\# .IL 2P
\# ...some text...
\# .IL 2P
\# ...some text...
\# .IQ
\# ...some text...
\# .IL
\# ...some text...
\#
\# The first .IL 2P indents text 2P from the left margin.  The second
\# .IL 2P indents text by an additional 2P, i.e. 4P from the left margin.
\# .IQ turns the indent off.  The last .IL (which has no argument)
\# takes its value from the total of all arguments passed to .IL (in
\# this case, 2P and 2P), therefore it indents 2P+2P from the left
\# margin, i.e. 4P.  If you wanted the last .IL to indent just 2P,
\# you'd either have to reset the .IL prior to .IQ (.IL -2P), or pass
\# the last .IL the argument 2P.
\#
\# To reverse the sense of an indent added to an indent, you may use
\# negative values.
\#
\# Indents can be turned off individually with ILX, IRX, and IBX.
\# LEFT and RIGHT indents may be combined and manipulated
\# separately, (e.g. you can have an IL of 2P and an IR of 4P
\# operative at the same time, and then change, say, the IL to
\# 4P--thereby left indenting 6P--while the IR remains at 4P.
\#
\# IB automatically turns off IL and IR.  They have to be reinvoked
\# again when needed. IL and IR automatically turn IB off; it, too,
\# has to be reinvoked with needed.
\#
\# All indents can be turned off at once with IQ.  The ILX, IRX, IBX,
\# and IQ macros simply turn the indents off; the values stored in
\# the respective indent macros (IL, IR, IB) remain in effect.  If
\# the user wishes to clear the values, the I<LRB>X macros should be
\# invoked with the single argument CLEAR.  IQ CLEAR clears out
\# the values stored for all indent styles.
\#
\# Indents *must* be turned off before settting string tabs
\# inside PAD.  Generally, in order not to get confused, it's a
\# good idea to turn all indents off before setting any tabs.
\#
\# TI and HI are special cases.  There's no need to turn them off,
\# since they affect only one line--the first after their
\# invocation.  Like the other indent styles, the first time
\# they're invoked, they require a value in iPpcm; each subsequent
\# invocation without an argument will use the same value.  To
\# change the value, simply pass a new value.  Values for TI and HI
\# are *not* additive.
\#
\# HI presupposes that you already have a left or both indent
\# on.  HI will never hang a line outside the left margin of a
\# document.  In other words, you must have IL or IB on before you
\# can use HI.

\#
\# THE START MACRO
\# ---------------
\# *Arguments:
\#   <none>
\# *Function:
\#   Reads in default document style parameters and any parameter
\#   the user has changed before issuing START.
\#   Using the information gathered in the opening macros,
\#   prints appropriate title (or chapter #), subtitle, author
\#   and document type (if appropriate).
\# *Notes:
\#   The .PRINT \& (zero-width character) is required to get the
\#   subsequent .sp request to work as advertised.
\#
\#   The overall document line length, family, and point-size
\#   are stored in #DOC_L_LENGTH, $DOC_FAM, and #DOC_PT_SIZE for
\#   use in the HEADER and FOOTER macros.
\#
\#  First, define some strings for point sizes

\# ------
\# *Arguments:

\# *Notes:
\#   In order to convert the title string to caps in the header (in the
\#   event that the user enters .TITLE in caps/lc), I've used
\#   quad left, quad centre, and quad right to arrange the three bits
\#   of the header, rather than .tl.  This allows the use of the CAPS macro.
\#   The downside is that I have to add \\v'-(\\n[#LEAD]u*#) in order
\#   for -Tlatin1 output to align the header/footer strings on the baseline.
\#   The console output still isn't brilliant, but at least it's
\#   comprehensible.

\# PARAGRAPH
\# ---------
\# *Arguments:
\#   <none>
\# *Function:
\#   Figures out what to do with paragraphs under differing conditions.
\# *Notes:
\#   For the time being, there's no automatic widow/orphan control.
\#   Controlling them isn't just a matter of establishing an arbitrary
\#   number of lines needed for a para, since groff doesn't then
\#   handle single line paragraphs gracefully.  Usually, the whole
\#   page needs to be tweaked.
\#
\#   Note the use of transparent line break (\!.br) to get
\#   PP to work within blockquotes and epigraphs.
\#
\#   PP_STYLE 1 = regular paras; 2 = blockquotes, epigraphs

\#   (viz. an extra line space).  TYPESET puts in only half
\#   line spaces if the entire quote plus 1 line of body under the quote
\#   fits on the the page; otherwise it puts in a full extra blank
\#   line.  (This is to ensure the page remains bottom aligned).

\# BREAK QUOTE
\# -----------
\# *Arguments:
\#   <none>
\# *Function:
\#   Ends the diversion P_QUOTE or B_QUOTE, breaks to a new
\#   page, and reinvokes BLOCKQUOTE.
\# *Notes:
\#   Because quotes go into a diversion before they're output,
\#   footnotes in quotes that cross pages behave erratically.  The footnote
\#   isn't processed until the diversion ends, hence the footnote
\#   marker in the quote isn't always correct for the new page (it's
\#   picked up from the old one).  BREAK_QUOTE is a workaround for
\#   this problem.

\# +++ENDNOTES+++
\#
\# When endnotes are output, the spacing between the notes is always 1
\# extra linespace.  This can have bottom margin consequences.  If this
\# doesn't bother you, don't worry about it.  If it does bother you, and
\# you want to adjust the spacing between any two endnotes (as they're
\# output), make the spacing adjustments (.ALD/.RLD) at the *end* of
\# endnotes (i.e. just before .ENDNOTE OFF), not at the top.
\#
\# Endnotes must be output manually with .ENDNOTES.  This allows user
\# the flexibility to output endnotes at the end of each collated
\# document, or to output them at the end of the entire document.

\#
\#   This size control macro differs from other size control macros
\#   in that it sets an absolute point size, not a relative one.  This
\#   is because a) endnotes always appear separate from the body of
\#   a document and therefore don't need to be relative to the body
\#   of the document, and b) there are quite a few elements of the
\#   endnotes page(s) that need to be relative to the base point size
\#   of that page.  If the base endnote point size were relative to
\#   the body of the document (i.e. a _SIZE macro taking a +|- value)
\#   getting the rest of the endnote elements sized properly could
\#   become very confusing.
