+
+<h2 id="docprocessing-intro" class="docs">Introduction to document processing</h2>
+
+<p>
+Document processing with mom uses markup tags to identify document elements
+such as heads, paragraphs, and so on. The tags are, of course,
+macros, but with sensible, readable names that make them easy
+to grasp and easy to remember. (And don&#8217;t forget: if you
+don&#8217;t like the &#8220;official&#8221; name of a tag &mdash;
+too long, cumbersome to type in, not &#8220;intuitive&#8221; enough
+&mdash; you can change it with the
+<a href="goodies.html#alias">ALIAS</a>
+macro.)
+</p>
+
+<p>
+In addition to the tags themselves, mom has an extensive array of
+macros that control how they look and behave.
+</p>
+
+<p>
+Setting up a mom doc is a simple, four-part procedure. You
+begin by entering information about the document itself (title,
+subtitle, author, etc.). Next, you tell mom what kind of document
+you&#8217;re creating (e.g. chapter, letter, abstract, etc...) and
+what kind of output you want (typeset, typewritten, draft-style,
+etc). Thirdly, you make as many or as few changes to mom&#8217;s
+default behaviour as you wish. Lastly, you invoke the
+<kbd><a href="#start">START</a></kbd>
+macro. Voilà! You&#8217;re ready to write.
+</p>
+
+<!-- ==================================================================== -->
+
+<h2 id="defaults" class="docs">Document defaults</h2>
+
+<p>
+As is to be expected, mom has defaults for everything. If you want
+to know a particular default, read about it in the description of
+the pertinent tag.
+</p>
+
+<p>
+I fear the following may not be adequately covered in the
+documentation, so just in case:
+</p>
+<ul style="margin-top: -.5em; margin-bottom: .5em;">
+ <li>the paper size is 8.5x11 inches</li>
+ <li>the left and right margins are 1-inch</li>
+ <li>the top and bottom margins for document text are plus/minus
+ visually 1-inch
+ </li>
+ <li>pages are numbered; the number appears centred, at the
+ bottom, surrounded by hyphens ( e.g. -6- )
+ </li>
+ <li>the first page of a document begins with a
+ <a href="definitions.html#docheader">document header</a>
+ </li>
+ <li>subsequent pages have
+ <a href="definitions.html#header">page headers</a>
+ with a rule underneath
+ </li>
+</ul>
+
+<!-- ==================================================================== -->
+
+<h2 id="leading-note" class="docs">Important note on leading/spacing and bottom margins</h2>
+
+<p>
+Mom takes evenly-aligned bottom margins in
+<a href="definitions.html#running">running text</a>
+very seriously. Only under a very few (exceptional) circumstances
+will she allow a bottom margin to &#8220;hang&#8221; (i.e. to fall
+short).
+</p>
+
+<p>
+In order to ensure even bottom margins, mom uses the
+&#8220;base&#8221; document
+<a href="definitions.html#leading">leading</a>
+in effect <i>at the start of running text on each page</i> (i.e.
+the leading used in paragraphs) to calculate the spacing of every
+document element. Prior to invoking
+<a href="#start">START</a>,
+this is set with the
+<a href="typesetting.html#macros-typesetting">typesetting macro</a>
+<a href="typesetting.html#leading">LS</a>,
+afterwards with the document
+<a href="definitions.html#controlmacro">control macro</a>
+<a href="#doc-lead">DOC_LEAD</a>.
+</p>
+
+<p>
+Because mom relies so heavily on the base document
+leading, any change to the leading or spacing on a page will almost
+certainly have undesirable consequences on that page&#8217;s bottom margin
+unless the change is fully compensated for elsewhere on the page.
+</p>
+
+<p>
+In other words, if you add a few points of space somewhere on a page,
+you must subtract the same number of points somewhere else on that
+same page, and vice versa.
+</p>
+
+<p>
+If it&#8217;s a question of adding or subtracting full
+line spaces between or within document elements, you
+can do so by using the &#8220;<kbd>v</kbd>&#8221; <a
+href="definitions.html#unitofmeasure">unit of measure</a> with
+whatever spacing macro you choose &mdash;
+<a href="typesetting.html#ald">ALD</a>,
+<a href="typesetting.html#rld">RLD</a>,
+<a href="typesetting.html#space">SPACE</a>
+&mdash; and mom won&#8217;t object. &#8220;<kbd>v</kbd>&#8221; means
+&#8220;the current leading&#8221;, so she isn&#8217;t confused by it. And
+since &#8220;<kbd>v</kbd>&#8221; accepts decimal fractions, you can add/subtract
+half linespaces and quarter linespaces with &#8220;<kbd>v</kbd>&#8221; as well,
+<i>provided you compensate for the fractional linespace somewhere
+else on the page</i>.
+</p>
+
+<p>
+If all this seems like too much work, mom provides a special macro
+to get you out of trouble if you&#8217;ve played around with leading
+and/or spacing. The macro is called SHIM (like those little pieces
+of wood carpenters use to get their work even, level and snug), and
+it&#8217;s described below.
+</p>
+
+<!-- -SHIM- -->
+
+<div class="macro-id-overline">
+<h3 id="shim" class="macro-id">SHIM</h3>
+</div>
+
+<div class="box-macro-args">
+Macro: <b>SHIM</b>
+</div>
+
+<p>
+SHIM doesn&#8217;t take any argument. Use it whenever you&#8217;ve played
+around with the
+<a href="definitions.html#leading">leading</a>
+or spacing on a page and you need to get mom&#8217;s document
+leading back on track.
+</p>
+
+<p>
+For example, say you want to insert a picture into a document with
+the special groff macro, PSPIC (see <kbd>man groff-tmac</kbd> for
+usage).
+</p>
+
+<p>
+Pictures aren&#8217;t usually conveniently sized in multiples of
+document leading, which means that when you insert the picture, you
+disrupt mom&#8217;s ordered placement of baselines on the page.
+This will certainly result in a bottom margin that doesn&#8217;t
+match the bottom margins of your document&#8217;s other pages.
+</p>
+
+<p>
+The solution is to insert SHIM after the picture,
+like this:
+<br/>
+<span class="pre-in-pp">
+ &lt;some lines of text&gt;
+ .PSPIC &lt;full path to picture&gt;
+ .SHIM
+ &lt;more lines of text&gt;
+</span>
+</p>
+
+<p>
+SHIM instructs mom to insert as much or a little space after the
+picture as is needed to ensure that the baseline of the next
+<a href="definitions.html#outputline">output line</a>
+falls where mom would have put it had you not disrupted the normal
+flow of output lines with the picture.
+</p>
+
+<p>
+And say, on previewing the above example, you find that the picture
+doesn&#8217;t centre nicely between the lines of text, you can
+always do
+<br/>
+<span class="pre-in-pp">
+ &lt;some lines of text&gt;
+ .RLD 3p
+ .PSPIC &lt;full path to picture&gt;
+ .SHIM
+ &lt;more lines of text&gt;
+</span>
+to raise the picture slightly (reverse lead 3 points; see
+<a href="typesetting.html#rld">RLD</a>),
+and still have SHIM ensure that text underneath falls exactly where
+it&#8217;s supposed to.

+<h3 id="docprocessing-tut" class="docs">Tutorial &ndash; Setting up a mom document</h3>
+
+<p style="margin-top: 1em;">
+There are four parts to setting up a mom doc (three, actually,
+with one optional). Before we proceed, though, be reassured that
+something as simple as
+<br/>
+<span class="pre-in-pp">
+ .TITLE "By the Shores of Lake Attica"
+ .AUTHOR "Rosemary Winspeare"
+ .PRINTSTYLE TYPESET
+ .START
+</span>
+produces a beautifully typeset 8.5x11 document, with a
+<a href="definitions.html#docheader">docheader</a>
+at the top of page 1,
+<a href="definitions.html#header">page headers</a>
+with the title and author on subsequent pages, and page numbers at
+the bottom of each page. In the course of the document, heads,
+subheads, citations, quotes, epigraphs, and so on, all come out
+looking neat, trim, and professional.
+</p>
+
+<p>
+For the purposes of this tutorial, we&#8217;re going to set up
+a short story&mdash;<i>My Pulitzer Winner</i>&mdash;by Joe Blow.
+Thankfully, we don&#8217;t have to look at story itself, just the
+setup. Joe wants the document
+</p>
+<ul style="margin-top: -.5em; margin-bottom: -.5em;">
+ <li>to be draft 7, revision 39;</li>
+ <li>to use the &#8220;default&#8221; style of document formatting:</li>
+ <li>to print as draft-style output (instead of &#8220;final&#8221; copy output);</li>
+ <li>to be typeset, in Helvetica, 12 on 14,
+ <a href="definitions.html#rag">rag-right</a>;
+ </li>
+ <li>to have <a href="definitions.html#footer">footers</a>
+ instead of
+ <a href="definitions.html#header">headers</a>;
+ </li>
+ <li>to use a single asterisk for
+ <a href="definitions.html#linebreak">author linebreaks</a>.
+ </li>
+</ul>
+
+<p>
+Joe Blow has no taste in typography. His draft won&#8217;t look
+pretty, but this is, after all, a tutorial; we&#8217;re after
+examples, not beauty.
+</p>
+
+<h4 class="docs" style="margin-top: -.5em;">Step 1</h4>
+
+<p style="margin-bottom: -.5em;">
+The first step in setting up any document is giving mom some
+reference information. The reference macros are:
+</p>
+<div style="width: 50%; float: left;">
+<ul>
+ <li>TITLE</li>
+ <li>DOCTITLE</li>
+ <li>COVERTITLE</li>
+ <li>DOC_COVERTITLE</li>
+ <li>SUBTITLE</li>
+ <li>AUTHOR</li>
+ <li>CHAPTER &ndash; the chapter number</li>
+</ul>
+</div>
+<div>
+<ul>
+ <li>DRAFT &ndash; the draft number</li>
+ <li>REVISION &ndash; the revision number</li>
+ <li>COPYRIGHT &ndash; only used on cover pages</li>
+ <li>MISC &ndash; only used on cover pages</li>
+ <li>COVER_TITLE &ndash; only on cover pages; only if needed</li>
+ <li>DOC_COVER_TITLE &ndash; only on document cover pages; only if needed</li>
+</ul>
+</div>
+
+<p style="margin-top: -.5em; clear: both;">
+You can use as many or as few as you wish, although at a minimum,
+you&#8217;ll probably fill in TITLE (unless the document&#8217;s a
+letter) and AUTHOR. Order doesn&#8217;t matter. You can separate
+the
+<a href="definitions.html#arguments">arguments</a>
+from the macros by any number of spaces. The following are what
+you&#8217;d need to start Joe Blow&#8217;s story.
+<br/>
+<span class="pre-in-pp">
+ .TITLE "My Pulitzer Winner"
+ .AUTHOR "Joe Blow"
+ .DRAFT 7
+ .REVISION 39
+</span>
+</p>
+
+<h4 class="docs" style="margin-top: -1.5em;">Step 2</h4>
+
+<p>
+Once you&#8217;ve given mom the reference information she needs, you
+tell her how you want your document formatted. What kind of
+document is it? Should it be typeset or typewritten? Is this a
+final copy (for the world to see) or just a draft? Mom calls
+the macros that answer these questions &#8220;the docstyle
+macros.&#8221; They are:
+</p>
+<ul style="margin-top: -.5em; margin-bottom: -.5em;">
+ <li>DOCTYPE&mdash;the type of document (default, chapter, user-defined, letter)</li>
+ <li>PRINTSTYLE&mdash;typeset or typewritten</li>
+ <li>COPYSTYLE &mdash;draft or final copy</li>
+</ul>
+
+<p>
+Mom has defaults for DOCTYPE and COPYSTYLE; if they&#8217;re what
+you want, you don&#8217;t need to include them here. However,
+PRINTSTYLE has no default and must be present in every formatted
+document. If you omit it, mom won&#8217;t process the document
+AND she&#8217;ll complain (both to stderr and as a single printed
+sheet with a warning). Moms&mdash;they can be so annoying
+sometimes. &lt;sigh&gt;
+</p>
+
+<p>
+Adding to what we already have, the next bit of setup for Joe
+Blow&#8217;s story looks like this:
+<br/>
+<span class="pre-in-pp">
+ .TITLE "My Pulitzer Winner"
+ .AUTHOR "Joe Blow"
+ .DRAFT 7
+ .REVISION 39
+ \#
+ .DOCTYPE DEFAULT \"Superfluous; mom uses DOCTYPE DEFAULT by default
+ .PRINTSTYLE TYPESET
+ .COPYSTYLE DRAFT
+</span>
+Notice the use of the
+<a href="definitions.html#commentlines">comment line</a>
+( <kbd>\#</kbd> ), a handy way to keep groups of macros visually
+separated for easy reading in a text editor.
+</p>
+
+<h4 class="docs" style="margin-top: -.5em; margin-bottom: -.5em;">Step 3</h4>
+
+<p>
+This step&mdash;completely optional&mdash;is where you, the
+user, take charge. Mom has defaults for <i>everything</i>, but
+who&#8217;s ever satisfied with defaults? Use any of the
+<a href="typesetting.html#macros-typesetting">typesetting macros</a>
+here to change mom&#8217;s document defaults (paper size, margins,
+family, point size, line space, rag, etc), or any of the document
+processing macros that set/change/control the appearance of document
+elements. Think of this as the &#8220;style-sheet &#8221; section
+of a document. And please note: you MUST give mom a
+<a href="#printstyle">PRINTSTYLE</a>
+directive <i>before</i> making any such changes.
+</p>
+
+<p>
+Joe Blow wants his story printed in Helvetica, 12 on 14, rag right,
+with
+<a href="definitions.html#footer">page footers</a>
+instead of
+<a href="definitions.html#header">page headers</a>
+and a single asterisk for the
+<a href="definitions.html#linebreak">linebreak</a>
+character. None of these requirements conforms to mom&#8217;s
+defaults for the chosen PRINTSTYLE (TYPESET), so we change them
+here. The setup for Joe Blow&#8217;s story now looks like this:
+<br/>
+<span class="pre-in-pp">
+ .TITLE "My Pulitzer Winner"
+ .AUTHOR "Joe Blow"
+ .DRAFT 7
+ .REVISION 39
+ \#
+ .DOCTYPE DEFAULT
+ .PRINTSTYLE TYPESET
+ .COPYSTYLE DRAFT
+ \#
+ .FAMILY H
+ .PT_SIZE 12
+ .LS 14
+ .QUAD LEFT \"i.e. rag right
+ .FOOTERS
+ .LINEBREAK_CHAR *
+</span>
+</p>
+
+<h4 class="docs" style="margin-top: -1.5em; margin-bottom: -.5em;">Step 4</h4>
+
+<p>
+The final step in setting up a document is telling mom to start
+document processing. It&#8217;s a no-brainer, just the single
+macro, START. Other than PRINTSTYLE, it&#8217;s the only macro
+required for document processing (although I can&#8217;t guarantee
+you&#8217;ll like the results of using just the two).
+</p>
+
+<p>
+Here&#8217;s the complete setup for <i>My Pulitzer Winner</i>:
+<br/>
+<span class="pre-in-pp">

+As pointed out earlier, Joe Blow is no typographer. Given that all he
+needs is a printed draft of his work, a simpler setup would have been:
+<br/>
+<span class="pre-in-pp">
+ .TITLE "My Pulitzer Winner"
+ .AUTHOR "Joe Blow"
+ .DRAFT 7
+ .REVISION 39
+ \#
+ .PRINTSTYLE TYPEWRITE
+ .COPYSTYLE DRAFT
+ \#
+ .START
+</span>
+<kbd>.PRINTSTYLE&nbsp;TYPEWRITE</kbd>, above, means that Joe&#8217;s
+work will come out &#8220;typewritten, double-spaced&#8221;,
+making the blue-pencilling he (or someone else) is sure to do much
+easier (which is why many publishers and agents still insist on
+typewritten, double-spaced copy).
+</p>
+
+<p>
+When J. Blow stops re-writing and decides to print off a final,
+typeset copy of his work for the world to see, he need only make two
+changes to the (simplified) setup:
+<br/>
+<span class="pre-in-pp">
+ .TITLE "My Pulitzer Winner"
+ .AUTHOR "Joe Blow"
+ .DRAFT 7
+ .REVISION 39
+ \#
+ .PRINTSTYLE TYPESET \"first change
+ .COPYSTYLE FINAL \"second change
+ \#
+ .START
+</span>
+In the above, <kbd>.DRAFT&nbsp;7,&nbsp;.REVISION 39,</kbd> and
+<kbd>.COPYSTYLE FINAL</kbd> are actually superfluous. The draft
+and revision numbers aren&#8217;t used when COPYSTYLE is FINAL,
+and <b>COPYSTYLE FINAL</b> is mom&#8217;s default unless you tell
+her otherwise.
+</p>
+
+<p>
+BUT... to judge from the number of drafts already,
+J. Blow may very well decide his &#8220;final&#8221; version still
+isn&#8217;t up to snuff. Hence, he might as well leave in the
+superfluous macros. That way, when draft 7, rev. 62 becomes draft
+8, rev. 1, he&#8217;ll be ready to tackle his Pulitzer winner again.

+<h3 id="doctype-underline" class="docs control">How to control DOCTYPE NAMED underlining</h3>
+
+<p style="tip">
+By default, the string passed to DOCTYPE <kbd>NAMED</kbd> is
+underlined in the docheader, and on document-cover pages and cover
+(&#8220;title&#8221;) pages. (See the
+<a href="cover.html#intro">Introduction to covers</a>
+for the difference between &#8220;doc cover&#8221; and
+&#8220;cover&#8221; pages.)
+</p>
+
+<p>
+Formerly, this underlining was carved in stone. As of version 1.5
+of mom, you can use the macro DOCTYPE_UNDERLINE to set the weight of
+the underline and its distance from where the doctype-name appears
+in the docheader (doc covers and covers handle underlining of the
+doctype-name differently; see
+<a href="cover.html#cover-underline">COVER_UNDERLINE</a>),
+or simply toggle doctype underlining on or off. Mom&#8217;s default
+is to underline the doctype-name.
+</p>
+
+<p>
+The order of arguments is <kbd>weight</kbd>, optionally followed by
+<kbd>gap</kbd>, where &#8220;gap&#8221; is the distance from the
+<a href="definitions.html#baseline">baseline</a>
+of the doctype-name to the underline.
+</p>
+
+<p>
+The <kbd>weight</kbd> argument is given in points, or fractions
+thereof, and must not have the
+<a href="definitions.html#unitofmeasure">unit of measure</a>,
+<kbd>p</kbd>, appended. Like
+<a href="inlines.html#rule-weight">RULE_WEIGHT</a>,
+weights must be greater than 0 and less than 100. Mom&#8217;s
+default for DOCTYPE <kbd>NAMED</kbd> underlining is 1/2 point.
+</p>
+
+<p>
+The <kbd>gap</kbd> argument can be given using any unit of measure,
+and must have the unit of measure appended to the argument.
+The distance of the gap is measured from the baseline of the
+DOCTYPE <kbd>NAMED</kbd> name to the upper edge of the underline.
+Mom&#8217;s default gap for named-doctype underlining is 2 points.
+</p>
+
+<p>
+As an example, supposed you want the doctype-name underlined in the
+docheader with a 2-point rule separated from the head by 3 points.
+The way to accomplish it is:
+<br/>
+<span class="pre-in-pp">
+ .DOCTYPE_UNDERLINE 2 3p
+</span>
+If you wanted the same thing, but were content with mom&#8217;s
+default gap of 2 points,
+<br/>
+<span class="pre-in-pp">
+ .DOCTYPE_UNDERLINE 4
+</span>
+would do the trick.
+</p>
+
+<p>
+If you merely want to toggle the underlining of
+the doctype-name in docheaders on or off, invoke
+<kbd>.DOCTYPE_UNDERLINE</kbd> by itself to turn the underlining on,
+or <kbd>.DOCTYPE_UNDERLINE&nbsp;OFF</kbd> (or NO, X, etc.)
+</p>
+
+<p class="tip-bottom">
+Please note that if you supply a weight to DOCTYPE_UNDERLINE, and
+optionally a gap, you also turn the underlining of the doctype-name
+in docheaders on; if this is not what you want, you must turn the
+underlining off manually afterwards.

+</p>
+
+<p>
+As mentioned above, PRINTSTYLE <kbd>TYPESET</kbd> must come before

+<br/>
+<span class="pre-in-pp">
+ .PRINTSTYLE TYPESET
+ .PAPER A4
+ .LS 14
+</span>
+will.
+</p>
+
+<p>
+With <kbd>TYPEWRITE</kbd>, mom does her best to reproduce the look
+and feel of typewritten, double-spaced copy (see

+(<kbd><a href="inlines.html#inline-size-mom">\*S[&lt;size&gt;]</a></kbd>
+is an exception; there may be a few others).
+</p>
+
+<p>
+In short, <kbd>TYPEWRITE</kbd> never produces effects
+other than those available on a typewriter. Don&#8217;t be fooled
+by how brainless this sounds; mom is remarkably sophisticated when
+it comes to conveying the typographic sense of a document within the

+</p>
+
+<p>
+The primary uses of <kbd>TYPEWRITE</kbd> are: outputting hard

+fellow writers for critiquing), simply change <kbd>TYPEWRITE</kbd>
+to <kbd>TYPESET</kbd> and print out a copy.

+<p>
+From time to time (or maybe frequently), you&#8217;ll want the
+overall look of a document to differ from mom&#8217;s defaults.
+Perhaps you&#8217;d like her to use a different
+<a href="definitions.html#family">family</a>,
+or a different overall
+<a href="definitions.html#leading">leading</a>,
+or have different left and/or right page margins.
+</p>
+
+<p>
+To accomplish such alterations, use the appropriate
+<a href="typesetting.html#macros-typesetting">typesetting macros</a>
+(listed below) after
+<a href="#printstyle">PRINTSTYLE</a>
+and before
+<a href="#start">START</a>.
+</p>
+
+<p>
+More than one user has, quite understandably, not fully grasped the
+significance of the preceding sentence. The part they&#8217;ve missed is
+<i>after</i> PRINTSTYLE.
+</p>
+
+<p>
+Changes to any aspect of the default look and/or formatting of a mom
+document must come after PRINTSTYLE. For example, it might seem
+natural to set up page margins at the very top of a document with
+<br/>
+<span class="pre-in-pp">
+ .L_MARGIN 1i
+ .R_MARGIN 1.5i
+</span>
+However, when you invoke <kbd>.PRINTSTYLE</kbd>, those margins

+all other changes to the look of a document&mdash;is <i>after</i>
+PRINTSTYLE.

+Other macros that deal with type style, or refinements thereof
+(<b>KERN, LIGATURES, HY, WS, SS,</b> etc.), behave normally.
+It is not recommended that you set up tabs or indents prior to
+START.
+</p>
+
+<p>
+If you want to change any of the basic parameters (above)
+<i>after</i> START and have them affect a document globally (as if
+you&#8217;d entered them <i>before</i> START), you must use the macros

+</p>
+
+<h4 id="lrc-note" class="docs">Special note on LEFT, RIGHT and CENTER prior to START</h4>

+In a word, these three macros have no effect on document processing

+
+<p>
+All mom&#8217;s document element tags (PP, HEAD, BLOCKQUOTE,
+FOOTNOTE, etc.) except
+<a href="docelement.html#quote">QUOTE</a>
+set a
+<a href="definitions.html#filled">fill mode</a>
+as soon as they&#8217;re invoked. If you wish to turn fill mode off
+for the duration of any tag (with
+<a href="typesetting.html#lrc">LEFT, RIGHT or CENTER</a>)
+you must do so immediately after invoking the tag. Furthermore,
+the change affects <i>only</i> the current invocation of the tag.
+Subsequent invocations of the same tag for which you want the same
+change require that you invoke <kbd>.LEFT</kbd>, <kbd>.RIGHT</kbd>
+or <kbd> CENTER</kbd> immediately after every invocation of the tag.
+</p>
+
+<!-- -INCLUDE- -->
+
+<h4 id="include" class="docs">Including (sourcing) style sheets and files</h4>
+
+<p>
+If you routinely make the same changes to mom&#8217;s defaults in
+order to create similar documents in a similar style&mdash;in other
+words, you need a template&mdash; you can create style-sheet files
+and include, or "source", them into your mom documents with the
+macro, INCLUDE. The right place for such style sheets is after
+<a href="#printstyle">PRINTSTYLE</a>
+and before
+<a href="#start">START</a>.
+</p>
+
+<p>
+Say, for example, in a particular kind of document, you always
+want main heads set in Helvetica Bold Italic, flush left,
+with no underscore. You&#8217;d create a file, let&#8217;s call it
+<kbd>head-template</kbd>, in which you&#8217;d place the pertinent HEAD
+control macros.
+<br/>
+<span class="pre-in-pp">
+ .HEAD_FAMILY H
+ .HEAD_FONT BI
+ .HEAD_QUAD L
+ .HEAD_UNDERLINE OFF
+</span>
+Then, in the preliminary document set-up section of your main file,
+you&#8217;d include the style sheet, or template, like this:
+<br/>
+<span class="pre-in-pp">
+ .TITLE "Sample Document
+ .AUTHOR "Joe Blow
+ .PRINTSTYLE TYPESET
+ \#
+ .INCLUDE head-template
+ \#
+ .START
+</span>
+
+The blank comment lines ( <kbd>\#</kbd> ) aren&#8217;t required, but
+they do make your file(s) easier to read.
+</p>
+
+<p>
+If the file to be included is in the same directory as the file
+you&#8217;re working, you simply enter the filename after
+<kbd>.INCLUDE</kbd>. If the file&#8217;s in another directory, you must
+provide a full path name to it. For example, if you&#8217;re working in
+a directory called <kbd>/home/joe/stories</kbd> and your
+style-sheet is in <kbd>/home/joe/style-sheets</kbd>, the above
+example would have to look like this:
+<br/>
+<span class="pre-in-pp">
+ .TITLE "Sample Document
+ .AUTHOR "Joe Blow
+ .PRINTSTYLE TYPESET
+ \#
+ .INCLUDE /home/joe/style-sheets/head-template
+ \#
+ .START
+</span>
+</p>
+
+<p>
+INCLUDE is not restricted to style sheets or templates. You can
+include any file at any point into a document, provided the file
+contains only text and valid groff or mom formatting commands.
+Neither is INCLUDE restricted to use with mom&#8217;s document
+processing macros. You can use it in plain typeset documents as
+well.

+</p>
+
+<p>
+When you invoke <kbd>.DOC_LEAD_ADJUST</kbd>, mom takes the number

+that fit on the page coincides perfectly with the bottom margin of
+<a href="definitions.html#running">running text</a>.
+</p>
+
+<p>
+In most instances, the difference between the requested lead and
+the adjusted lead is unnoticeable, and since in almost all cases
+adjusted leading is what you want, it&#8217;s mom&#8217;s default
+and you don't have to invoke it explicitly.
+</p>
+
+<p>
+However, should you not want adjusted document leading, you must
+turn it off manually, like this:
+<br/>
+<span class="pre">

+<h4 id="change-start" class="docs">1. Change the starting position of the docheader</h4>
+
+<p>
+By default, a docheader starts on the same
+<a href="definitions.html#baseline">baseline</a>
+as
+<a href="definitions.html#running">running text</a>.
+If you&#8217;d like it to start somewhere else, use the macro,
+DOCHEADER_ADVANCE, and give it the distance you want (measured from
+the top edge of the paper to the first baseline of the docheader),
+like this:
+<br/>
+<span class="pre-in-pp">
+ .DOCHEADER_ADVANCE 4P
+</span>
+A
+<a href="definitions.html#unitofmeasure">unit of measure</a>
+is required.
+</p>
+
+<div class="box-tip">
+<p class="tip">
+<span class="note">Note:</span>
+If
+<a href="headfootpage.html#headers">HEADERS</a>
+are <kbd>OFF</kbd>, mom&#8217;s normal top margin for
+<a href="definitions.html#running">running text</a>
+(7.5
+<a href="definitions.html#picaspoints">picas</a>)
+changes to 6 picas (visually approx. 1 inch). Since the first
+baseline of the docheader falls on the same baseline as the first
+line of running text (on pages after page 1), you might find the
+docheaders a bit high when headers are off. Use DOCHEADER_ADVANCE
+to place them where you want.
+</p>
+</div>
+
+<h4 id="docheader-quad" class="docs">2. Change the quad direction of the docheader</h4>
+
+<p>
+By default, mom centers the docheader. If you&#8217;d prefer to
+have your docheaders set flush left or right, or need to restore
+the default centering, invoke <kbd>.DOCHEADER_QUAD</kbd> with the
+quad direction you want, either <kbd>LEFT</kbd> (or <kbd>L</kbd>),
+<kbd>RIGHT</kbd> (or <kbd>R</kbd>) or <kbd>CENTER</kbd> (or
+<kbd>C</kbd>).
+</p>
+
+<h4 id="docheader-family" class="docs">3. Change the family of the entire docheader</h4>
+
+<p>
+By default, mom sets the docheader in the same
+family used for
+<a href="definitions.html#running">running text</a>.
+If you&#8217;d prefer to have your docheaders set in a different
+family, invoke <kbd>.DOCHEADER_FAMILY</kbd> with the family you
+want. The argument to DOCHEADER_FAMILY is the same as for
+<a href="typesetting.html#family">FAMILY</a>.
+</p>
+
+<p>
+For example, mom&#8217;s default family for running text is Times
+Roman. If you&#8217;d like to keep that default, but have the
+docheaders set entirely in Helvetica,
+<br/>
+<span class="pre-in-pp">
+ .DOCHEADER_FAMILY H
+</span>
+is how you&#8217;d do it.
+</p>
+
+<p>
+Please note that if you use DOCHEADER_FAMILY, you can still alter
+the family of individual parts of the docheader with the macros
+listed
+<a href="#change-family">here</a>.
+</p>
+
+<h4 id="change-family" class="docs">4. Change the family of individual docheader elements</h4>

+
+<p>
+The following macros let you adjust the point size of each docheader

+</p>
+
+<p>
+Mom calculates the point size of docheader elements from the point
+size of paragraphs in running text, so you must prepend a + or -

+
+<h4 id="adjust-leading" class="docs">7. Adjust the docheader leading</h4>
+
+<p>
+The
+<a href="definitions.html#leading">leading</a>
+of docheaders is the same as running text. If you&#8217;d like your
+docheaders to have a different leading, say, 2 points more than the
+lead of running text, use:
+<br/>
+<span class="pre-in-pp">
+ .DOCHEADER_LEAD +2
+</span>
+Since the leading of docheaders is calculated from the lead of running
+text, a + or - sign is required before the argument (how much to add

+
+<h4 id="docheader-color" class="docs">8. Change the colour of the entire docheader</h4>

+<br/>
+<span class="pre-in-pp">

+in the strings passed to TITLE, CHAPTER_TITLE, SUBTITLE, AUTHOR or

+with the result that an embedded colour will cause the string to be

+control macros.)
+</p>
+
+<h4 id="change-attribute" class="docs">10. Change the attribution string (&#8220;by&#8221;)</h4>
+
+<p>
+If you&#8217;re not writing in English, you can change what mom
+prints where &#8220;by&#8221; appears in docheaders. For example,
+<br/>
+<span class="pre-in-pp">
+ .ATTRIBUTE_STRING "par"
+</span>
+changes &#8220;by&#8221; to &#8220;par&#8221;. ATTRIBUTE_STRING
+can also be used, for example, to make the attribution read
+&quot;Edited by&quot;.
+</p>
+
+<p>
+If you don&#8217;t want an attribution string at all, simply pass
+ATTRIBUTE_STRING an empty argument, like this:
+<br/>
+<span class="pre-in-pp">
+ .ATTRIBUTE_STRING ""
+</span>
+Mom will deposit a blank line where the attribution string normally
+appears.
+</p>
+
+<p>
+If the optional argument, <kbd>COVER</kbd> or <kbd>DOC_COVER</kbd>,
+is given to ATTRIBUTE_STRING, the string argument represents the
+attribution string that will appear on cover or document cover pages
+(see the
+<a href="cover.html#cover-intro">Introduction to cover pages</a>
+for a description of the difference between &#8220;document
+covers&#8221; and &#8220;covers&#8221;). Thus, it is possible to
+have different attribution strings on the document cover page, the
+cover (&#8220;title&#8221;) page, and in the first-page docheader.
+An extreme example would be:
+<br/>
+<span class="pre-in-pp">
+ .ATTRIBUTE_STRING ""
+ .ATTRIBUTE_STRING DOC_COVER "Edited by"
+ .ATTRIBUTE_STRING COVER "by"
+</span>
+The first invocation of <kbd>.ATTRIBUTE_STRING</kbd> establishes a
+blank attribution string that will be incorporated in the first-page
+docheader. The second will print &#8220;Edited by&#8221; on the
+document cover; the third will print &#8220;by&#8221; on the cover
+(&#8220;title&#8221;) page.
+</p>
+
+<p>
+If you don&#8217;t require differing attribute strings for
+doc cover pages, cover pages, or the first-page docheader,
+<kbd>.ATTRIBUTE_STRING</kbd>, without either of the optional first
+arguments, is sufficient.
+</p>
+
+<div class="box-tip">
+<p class="tip">
+<span class="note">Note:</span>
+The type specs for the attribution line in docheaders are the

+or point size, you can make such changes using
+<a href="definitions.html#inlines">inline escapes</a>
+in the argument to ATTRIBUTE_STRING. For example,
+<br/>
+<span class="pre-in-pp">
+ .ATTRIBUTE_STRING "\f[HBI]\*[SIZE -2p] by \*[SIZE +2p]\*[PREV]"
+</span>
+would set &#8220;by&#8221; in Helvetica bold italic, 2 points

+<h2 id="columns-intro" class="docs">Setting documents in columns</h2>
+
+<p>
+Setting documents in columns is easy with mom. All you have to do
+is is say how many columns you want and how much space you want
+between them (the
+<a href="definitions.html#gutter">gutters</a>).
+That&#8217;s it. Mom takes care of everything else, from soup to
+nuts.
+</p>
+
+<h3 class="docs">Some words of advice</h3>
+
+<p>
+If you want your type to achieve a pleasing
+<a href="definitions.html#just">justification</a>
+or
+<a href="definitions.html#rag">rag</a>
+in columns, reduce the point size of type (and probably the
+<a href="definitions.html#leading">leading</a>
+as well). Mom&#8217;s default document point size is 12.5, which
+works well across her default 39
+<a href="definitions.html#picaspoints">pica</a>
+full page line length, but with even just two columns on a page, the
+default point size is awkward to work with.
+</p>
+
+<p>
+Furthermore, you&#8217;ll absolutely need to reduce the indents for
+<a href="docelement.html#epigraph-control">epigraphs</a>,
+<a href="docelement.html#quote-general">quotes</a>,
+and
+<a href="docelement.html#blockquote-general">blockquotes</a>

+as well).

+
+<p>
+During document processing, most of the
+<a href="typesetting.html#macros-typesetting">typesetting macros</a>
+affect type in the document globally. For example, if you turn
+kerning off, pairwise kerning is disabled not only in paragraphs,
+but also in headers, footers, quotes, and so on.
+</p>
+
+<p>
+Typesetting macros that alter margins and line lengths affect
+<a href="definitions.html#running">running text</a>
+globally (or at least try to), but leave headers/footers and
+footnotes alone. (To indent footnotes, see the full explanation of
+the
+<a href="docelement.html#footnote">FOOTNOTE</a>
+macro.)
+</p>
+
+<p>
+Mom&#8217;s tabs (both
+<a href="typesetting.html#typesetting-tabs">typesetting tabs</a>
+and
+<a href="typesetting.html#string-tabs">string tabs</a>)
+behave as expected in running text during document processing. Tab
+structures that do not exceed the line length of running text are
+preserved sensibly from page to page, and, if
+<a href="docprocessing.html#columns">COLUMNS</a>
+are enabled, from column to column.
+</p>
+
+<p>
+Some typesetting macros, however, when used during document
+processing, behave in special ways. These are the macros that deal
+with the basic parameters of type style: horizontal and vertical
+margins, line length,
+<a href="definitions.html#family">family</a>,
+<a href="definitions.html#font">font</a>,
+<a href="definitions.html#ps">point size</a>,
+<a href="definitions.html#leading">leading</a>,
+and
+<a href="definitions.html#quad">quad</a>.
+</p>
+
+<p>
+Mom assumes that any changes to these parameters stem from a
+temporary need to set type in a style different from that provided
+by mom&#8217;s
+<a href="docelement.html#index-docelement">document element tags</a>.
+In other words, you need to do a bit of creative typesetting in the
+middle of a document.
+</p>
+
+<p>
+The following lists those typesetting macros whose behaviour during
+document processing requires some explanation.
+(Please refer to
+<a href="#tb-margins">Top and bottom margins in document processing</a>
+for information on how mom interprets
+<a href="typesetting.html#t-margin">T_MARGIN</a>
+and
+<a href="typesetting.html#b-margin">B_MARGIN</a>
+in document processing. Additionally, see
+<a href="#add-space">ADD_SPACE</a>
+if you encounter the problem of trying to get mom to put space at
+the tops of pages after the first.)

+ MACRO EFFECT DURING DOCUMENT PROCESSING
+ ----- ---------------------------------
+
+ L_MARGIN &bull;The left margin of all running text
+ assumes the new value.
+
+ &bull;The line length remains unaltered.
+
+ &bull;The header and footer left margin
+ remain at the current document default.
+
+ (You won&#8217;t use this often by itself. Most
+ likely, you&#8217;ll use it in combination with
+ R_MARGIN or LL.)
+
+ R_MARGIN &bull;The right margin of all running text
+ assumes the new value. In other words,
+ the line length is altered.
+
+ &bull;The header and footer right margin
+ remain at the current document default.
+
+ LL &bull;The line length of all running text
+ is set to the new value.
+
+ &bull;The header and footer line length remain
+ at the current document default.
+
+ FAMILY &bull;Changes family for the duration of the
+ current tag only. As soon as another document
+ element tag is invoked, the family reverts to
+ the current default for the new tag.
+
+ FT &bull;Changes font for the duration of the
+ current tag only. As soon as another document
+ element tag is entered, the font reverts
+ to the current default for the new tag.
+
+ N.B. &mdash; \&bull;[SLANT] and \&bull;[BOLDER] affect
+ paragraph text, and remain in effect for all
+ paragraphs until turned off. If you want to
+ use them in a macro that takes a string
+ argument, include the escape in the string.
+ \&bull;[COND] and \&bull;[EXT] behave similarly.
+
+ PT_SIZE &bull;Changes point size for the duration of the
+ current tag only. As soon as another document
+ element tag is entered, the point size reverts
+ to the current document default for the new
+ tag.
+
+ LS &bull;Changes line space for the duration of the
+ current tag only. As soon as another document
+ element tag is entered, the line space reverts
+ to the current document default for the new
+ tag.
+
+ Using LS to temporarily change leading within
+ a document will almost certainly result in a
+ bottom margin that doesn&#8217;t align with
+ the bottom margin of subsequent pages. You&#8217;ll
+ need to use the SHIM macro to get mom back on
+ track when you&#8217;re ready to return to the
+ document&#8217;s default leading.
+
+ QUAD &bull;Changes quad for the duration of the
+ current tag only. As soon as another document
+ element tag is entered, the quad reverts to
+ the current document default for the new
+ tag.

+<h3 id="tb-margins" class="docs" style="margin-top: 1.5em;">Top and bottom margins in document processing</h3>
+
+<p>
+Normally, mom establishes the top and bottom
+margins of
+<a href="definitions.html#running">running text</a>
+in documents from the values of <b>HEADER_MARGIN +
+HEADER_GAP</b> and <b>FOOTER_MARGIN + FOOTER_GAP</b>
+respectively. However, if you invoke
+<a href="typesetting.html#t-margin">T_MARGIN</a>
+or
+<a href="typesetting.html#b-margin">B_MARGIN</a>
+either before or after
+<a href="docelement.html#start">START</a>,
+they set the top and bottom margins of running text irrespective of
+HEADER_GAP and FOOTER_GAP.
+</p>
+
+<p>
+Put another way, in document processing, T_MARGIN
+and B_MARGIN set the top and bottom margins of
+running text, but have no effect on the placement of
+<a href="definitions.html#header">headers</a>,
+<a href="definitions.html#footer">footers</a>,
+or page numbers.
+</p>

+
+<h3 id="space" class="docs">Inserting space at the top of a new page</h3>
+
+<p>
+Occasionally, you may want to insert space before the start of
+<a href="definitions.html#running">running text</a>
+on pages after the first.
+</p>
+
+<p>
+You might have tried using
+<a href="typesetting.html#ald">ALD</a>
+or
+<a href="typesetting.html#space">SPACE</a>
+and found it did nothing. This is because mom normally inhibits
+any extra space before the start of running text on pages after the
+first.
+</p>
+
+<p>
+If you need the space, you must use the macro, ADD_SPACE, in
+conjuction with
+<a href="typesetting.html#newpage">NEWPAGE</a>.
+</p>
+
+<!-- -ADD_SPACE- -->
+
+<div class="macro-id-overline">
+<h3 id="add-space" class= "macro-id">ADD_SPACE</h3>
+</div>

+</div>
+
+<p class="requires">
+&bull;&nbsp;Requires a <a href="definitions.html#unitofmeasure">unit of measure</a>
+</p>
+
+<p>
+ADD_SPACE takes as its single argument the distance
+you want mom to advance from the normal
+baseline position at the top of any page after the first
+(i.e. the one on which the docheader is normally printed). A
+<a href="definitions.html#unitofmeasure">unit of measure</a> is
+required.
+</p>
+
+<p>
+For example, say you wanted to insert 2 inches of space before the
+start of
+<a href="definitions.html#running">running text</a>
+on a page other than the first. You&#8217;d accomplish it with
+<br/>
+<span class="pre-in-pp">
+ .NEWPAGE
+ .ADD_SPACE 2i
+</span>
+which would terminate your current page, break to a new page, print
+the header (assuming headers are on) and insert 2 inches of space
+before the start of running text.
+</p>
+
+<p>
+Since adding space in this way is almost sure to disrupt mom&#8217;s
+ability to guarantee perfectly flush bottom margins, I highly
+recommend using the
+<a href="docprocessing.html#shim">SHIM</a>
+macro immediately after ADD_SPACE.
