<p>
Recto/verso printing allows you to set up a mom document in such
a way that it can be printed on both sides of a printer sheet and
subsequently bound.
</p>

<p>
With recto/verso, mom automatically takes control of the following
aspects of alternating page layout:
</p>
<ul style="margin-top: -.5em; margin-left: -.5em; margin-bottom: -.5em;">
  <li>switching left and right margins (if they&#8217;re not equal)</li>
  <li>switching the left and right parts of the default 3-part
      <a href="definitions.html#header">headers</a>
      or
      <a href="definitions.html#footer">footers</a>
      (see the
      <a href="headfootpage.html#description-general">General description of headers</a>)
  </li>
  <li>switching
      <a href="headfootpage.html#hdrftr-recto">HEADER_RECTO</a>
      and
      <a href="headfootpage.html#hdrftr-recto">HEADER_VERSO</a>
      if user-defined, single string recto/verso headers
      or footers are used in place of the default 3-part
      headers or footers
  </li>
  <li>switching the page number position (if page numbers are not centred)</li>
</ul>
<br/>

<div class="macro-list-container">

  <li><a href="#switch-hdrftr">SWITCH_HEADERS (also FOOTERS)</a>

</div>

<div id="recto-verso" class="box-macro-args">
Macro: <b>RECTO_VERSO</b>
</div>

<p>
If you want mom to set up alternating pages for recto/verso
printing, simply invoke RECTO_VERSO, with no argument, anywhere in
your document (most likely before
<a href="docprocessing.html#start">START</a>).
</p>

<div class="box-tip">
<p class="tip-top">
<span class="note">Note:</span>
Recto/verso always switches the left and right parts of
<a href="definitions.html#header">headers</a>
or
<a href="definitions.html#footer">footers</a>
on odd/even pages.  However, it only switches the left and right
margins if the margins aren&#8217;t equal.  Consequently, it is
your responsibility to set the appropriate differing left and right
margins with
<a href="typesetting.html#l-margin">L_MARGIN</a>
and
<a href="typesetting.html#r-margin">R_MARGIN</a>
(prior to
<a href="docprocessing.html#start">START</a>)
or with
<a href="docprocessing.html#doc-left-margin">DOC_LEFT_MARGIN</a>
and
<a href="docprocessing.html#doc-right-margin">DOC_RIGHT_MARGIN</a>
(before or after START).
</p>

<p class="tip-bottom">
Equally, recto/verso only switches the page number position if page
numbers aren&#8217;t centred, which means you have to set the page
number position with
<a href="headfootpage.html#pagenum-pos">PAGENUM_POS</a>
(before or after START).
</p>
</div>

<div id="force-recto" class="box-macro-args" style="margin-top: 1em;">
Macro: <b>FORCE_RECTO</b>
</div>

<p>
It is a common convention with two-sided printing to ensure that
cover pages, title pages, and chapters or major sections of a document
always begin on the recto side of a page.  This sometimes
necessitates inserting a blank page before the start of a new
chapter or major section.
</p>

<p>
If you would like mom to take care of this for you automatically,
simply invoke <kbd>FORCE_RECTO</kbd> before the first
<a href="docprocessing.html#start">START</a>
of the document.
</p>

<div id="switch-hdrftr" class="box-macro-args" style="margin-top: 1em;">
Macro: <b>SWITCH_HEADERS</b>
</div>

<p>
SWITCH_HEADERS switches the location of the header left string
(by default, the author) and the header right string (by default,
the document title).  If you don&#8217;t like mom&#8217;s default
placement of author and title, use SWITCH_HEADERS to reverse it.
</p>

<p>
SWITCH_HEADERS can also be useful in conjunction with
<a href="#recto-verso">RECTO_VERSO</a>.
The assumption of RECTO_VERSO is that the first page of a document
(ie recto/odd) represents the norm for header-left and header-right,
meaning that the second (and all subsequent verso/even) pages of the
document will reverse the order of header-left and header-right.
</p>

<p>
If mom&#8217;s behaviour in this matter is not what you want, simply
invoke SWITCH_HEADERS on the first page of your recto/verso document
to reverse her default treatment of header parts.  The remainder of
your document (with respect to headers) will come out as you want.
</p>

<h2 id="collate-intro" class="docs">Introduction to collating</h2>

<p>
Many people wisely keep chapters of a long work in separate
files, previewing or printing them as needed during the draft
phase.  However, when it comes to the final version, mom requires
a single, collated file in order to keep track of page numbering
and recto/verso administration, generating tables of contents and
endnotes, ensuring that
<a href="definitions.html#docheader">docheaders</a>
get printed correctly, and a host of other details.
</p>

<p>
The COLLATE macro, which can be used with any
<a href="docprocessing.html#doctype">DOCTYPE</a>
except <kbd>LETTER</kbd>, lets you glue mom-formatted text files
together.  You need only concatenate chapters into a single file
(most likely with the <kbd>cat</kbd> command), put <kbd>.COLLATE</kbd> at the end of each
concatenated chapter, follow it with the
<a href="docprocessing.html#reference-macros">reference macros</a>
(metadata) needed for the new chapter, e.g.,
<a href="docprocessing.html#chapter">CHAPTER</a>
or
<a href="docprocessing.html#chapter-string">CHAPTER_STRING</a>,
make any pertinent style changes to the upcoming chapter (unlikely,
but possible), and re-invoke the
<a href="docprocessing.html#start">START</a>
macro.  (Most likely, the metadata and <kbd>.START</kbd> are
already there.)  Each chapter will begin on a fresh page and behave
as expected.
</p>

<p>
Even if you always work with monolithic, multi-chapter files, every
chapter and its associated metadata plus <kbd>.START</kbd>
still needs to be preceded by a <kbd>.COLLATE</kbd> command.
</p>

<div class="box-tip">
<p class="tip">
<span class="note">Note:</span>
COLLATE assumes you are collating documents/files with similar
type-style parameters hence there&#8217;s no need for PRINTSTYLE
to appear after COLLATE, although if you&#8217;re collating
documents that were created as separate files, chances are the
PRINTSTYLE&#8217;s already there.
</p>
</div>

<div class="box-tip">
<p id="caution" class="tip">
<b>Two words of caution:</b>
</p>
<ol style="margin-top: -1.25em; padding-bottom: .5em;">
  <li>Do not collate documents of differing
      PRINTSTYLES (ie don&#8217;t try to
      collate a <kbd>TYPESET</kbd> document and <kbd>TYPEWRITE</kbd>
      document).
  </li>
  <li>Use <kbd>.DOC_FAMILY</kbd> instead of
      <kbd>.FAMILY</kbd> if, for some reason, you want to
      change the family of all the document elements after
      <kbd>.COLLATE</kbd>. <kbd>.FAMILY</kbd>, by itself, will
      change the family of paragraph text only.
  </li>
</ol>
</div>

<div class="macro-id-overline">
<h3 id="collate" class="macro-id">collate</h3>
</div>

<div class="box-macro-args">
Macro: <b>COLLATE</b>
</div>

<p>
The most basic (and most likely) collating situation looks like
this:
<br/>
<span class="pre-in-pp">
  .COLLATE
  .CHAPTER 17
  .START
</span>
A slightly more complex version of the same thing, for chapters
that require their own titles, looks like this:
<br/>
<span class="pre-in-pp">
  .COLLATE
  .CHAPTER_TITLE "Geek Fatigue: Symptoms and Causes"
  .START
</span>
</p>

<div class="box-tip" style="margin-top: -1em">
<p class="tip">
<span class="tip">Tip:</span>
If the last line of text before <kbd>.COLLATE</kbd>
falls too close to the bottom margin, or if the line is followed
by a macro likely to cause a linebreak (e.g., <kbd>.LIST OFF</kbd> or
<kbd>.IQ</kbd>), mom may output a superfluous blank page before
the start of the following document.
</p>

<p class="tip-bottom">
In order to avoid this, insert
<a href="docprocessing.html#EL"><kbd>.EL</kbd></a>
after the last line of text, before <kbd>.COLLATE</kbd> and/or any
concluding macros.  For example,
<br/>
<span class="pre-in-pp">
  some concluding text.\c
  .EL
  .COLLATE
</span>
or
<br/>
<span class="pre-in-pp">
  some concluding text.\c
  .EL
  .LIST OFF
  .COLLATE
