   \sec The main loop over Bible books
   %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
   The \`\processbooks` macro does two loops over all marks in \^`\printedbooks`.
   The macro \`\printedbooks` is a list of `<a-marks>` of Bible books separated by spaces
   and it must be defined in the main file. The `\_useit` trick is used here
   in order we want to add `<space>{}` at the end of the expanded
   \^`\printedbooks`.
   The first loop body sets \`\pbook!``<a-mark>` used for hyperlinks.
   The second loop body does:
   \begitems
   * Defines \`\amark` as <a-mark> (an actual mark of the book used in the text).
   * Defines \`\bmark` as <b-mark> (a mark of the book used in file names).
   * Defines \`\.btit` as the book title.
   * Saves `<a-mark>` to the \`\.currbook` macro.
   * Calls \^`\.newbook{<a-mark>}`
   * Prints title of the book to the terminal and to the log.
   * Calls \^`\bex!<a-mark>` in order to apply the \^`\BookException` data.
   * Inputs introduction file if it exists. The real `\input` and formating
     of the introduction text is done by the `\.printintro` macro.
   * Inputs format definition file if it exists. Information is saved to the
     \TeX/ memory.
   * Inputs notes file if it exists. The notes are saved to the \TeX/ memory.
   * Calls \^`\bpr!<a-mark>` in order to apply the \^`\BookPre` data.
   * Inputs `txs` file with original text of the Bible using \`\.bibleinput`,
     i.e.\ prints the text from `txs` file with notes from the \TeX/ memory.
   * Calls \^`\bpo!<a-mark>` in order to apply \^`\BookPost` data.
   \enditems
   Note that the macros \`\introfile`, \`\fmtfile`, and \`\notesfile`
   give the location of aprropriate files and these macros must be defined
   by the user in the main file.\nl
   Note2: each book of the Bible is processed in the group.
   It means that all data from notes, formats etc. are stored
   in the memory only temporary for processing single book. After
   the Book is finalized, the \TeX/ memory is freed.

   \sec Actions
   %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
   We create the output in two steps. First step: the data from \^`\Note`
   etc.\ are read and saved to the \TeX/ memory. For each such data element the
   \"action" is registered to a list of actions of the given verse. Each
   Bible verse has its list of actions.
   The second step: the Bible verses are read from a `.txs`
   file and all appropriate actions (registered to this verse) are
   processed before the verse text is printed. These actions can modify the
   selected parts of the verse text.\nl
   \`\alist!``<full-vref>` is the list of actions associated with the verse
   `<full-vref>`. The <full-vref> is full reference to the verse in the format
               <book-mark>/<chapter-num>:<verse-num>\nl
   \`\.newaction``{<full-vref>}{<action-body>}` allocates new action.

   A typical \"action" is `\.replpre`. The actions are processed for each
   Bible verse when the verse text is saved to the \^`\.buff` macro. The
   \^`\.buff` macro is processed after all actions of given verse are done.\nl
   \`\.replpre``{<prefix>}{<text>}{<fail>}` replaces first occurrence of <text>
   by `<prefix>{<text>}` in `\.buff` macro. If the <text> is empty then
   `<prefix>{}` is inserted at the beginning of the \^`\.buff`.

   The \^`\.replprepost` is used by \^`\fmtins` (with empty <pre>) because we want to insert the

   The \^`\fmtkeep` uses \^`\.replprepost` with empty <pre> and <post> together.

   The first parameter of the \^`\Note` macro is `<gen-vref>`.
   It is generalized reference to the Bible verse. It can be
   `<chapter-num>:<verse>` (the <book-mark> is appended from
   the \^`\.currbook` macro) or `<chapter-num>:<verse-from>-<verse-to>`
   (only <verse-from> is used for generating <gen-vref>.\nl

   \_doc
   The `<word>` given as a parameter of the \^`\Note` macro (see bellow) is used as a word
   phrase which should be be searched in the given verse text. This parameter `<word>`
   is transformed first by expansion of \^`\.transformword{<word>}` to the `<tword>` variant
   and the `<tword>` is actually used for searching. The \`\.transformword``{<word>}`
   expands to the variant of the <word> declared by `\.vdef`. If not declared then it
   expands to the <word> itself, i.e <tword> is equal to <word> in this case.

   \^`\.doNote{<note-num>}{<tword>}` in given verse. 
   \nl
   There is an alternative syntax 
   \^`\Note <gen-vref> <space> {<word>}={<pword>} <text> \par`
   If <pword> is given then it is printed in the note instead <tword>.
   More precisely: transformed <word> is used for searching
   (and it is kept in the verse unchanged) but <pword> is
   printed in the note.\nl
   The \^`\ww` can precede \^`\Note`. If it is true then the <word> is prepared in
   \^`\.nextww` and `<pword>` is in \^`\.nextwwA`. Otherwise, the macros \^`\.nextww`
   and \^`\.nextwwA` are undefined.\nl
   `\Note` does exactly following:
   \begitems
   * Calculates <full-vref> using `\.gentovref{<genv-ref>}` and svese it to
     \`\.fullvref`.
   * If the verse number of <full-vref> is zero, we want to insert the
     note-text before the chapter. This is one by the \^`\.NoteB` macro.
   * Allocates new <note-num>, i.e. \`\.notenum` is <note-num>.
   * Modifies <full-vref> if \^`\renum` was declared using `\.renumvref` and
     saves the result to \`\.fullvrefm`.
   * Uses \^`\.nextww` and \^`\.nextwwA` as <tword> and <pword> if they are defined.
   * Otherwise transforms <word> to <tword> by \^`\.transformword`.
   * Reads <pword> (word to be printed in the note) by `\.NoteA` if the alternative syntax
     with `={<pword>}` is used. Else <pword> is equal to <tword>.
     Use it only if \^`\.nextww` is undefined.
   * Defines \`\notetext!``<note-num>` as <text>.
   * Defines \`\noteref!``<note-num>` as <full-vref> re-calulated by \^`\renum`.
   * Defines \`\notepre!``<note-num>` as numeric part of modified <full-vref>.
     and calculates <from>-<to> part (if exists in <gen-vref>) using \^`\.renumlabel` macro.
     This is printed prefix of the `\Note`.
   * Defines \`\pword!``<note-num>` as <pword>,
   * Does

   * \`\.ltextB` ... the book mark followed by `~`

   * \`\.ltextV` ... the verse number
   * \`\.ltextS` ... sub-verse identifier (`a` if there is a verse `4a`)
   * \`\.ltextF` ... the `--` if the `<from>-<to>` format is given
   * \`\.ltextN` ... the `<to>` part from the `<from>-<to>` format.

   We don't create destinations for all verses, notes etc. but only for
   those which are referenced.
   The macro \`\.ensuredest` is called from \^`\.createlink` and it saves immediatelly
   `\sdef{<link>:<full-vref>}{}`
   to the special file `\jobname.xrf`. And the macro \^`\pg` saves immediatelly
   `\sdef{pg:<link>:<full-vref>}{??}` to this file.
   This `.xrf` file is read before standard
   `.ref` file. All link destinations save `\.Xdest{<full-vref>}` to the
   `.ref` file. The macro \`\.Xdest` does nothing if `\pg:<link>:<full-vref>` is not
   defined (from `.xrf` file). Otherwise, it is defined as a correct pageno.
   This result is used in the \^`\pg` macro.
   If `\<link>:<full-vref>` is not defined, no link destination is crated.
   First \TeX/ run creates `.ref` and `.xrf` files and does not create any
   hyperlink destinations. Second \TeX/ run uses data from these files

   `\skip\.noteins`. The \^`\.noteins` material is prefixed by `\penalty0` (in
   order to allow the next `\vsplit` operation) and the `\vfil` is added (in order
   to the case when the second column is smaller than the first one).
   The `\splittopskip` is set and first `\vsplit to0pt` adds skip given by
   `\splittopskip` to the \^`\.noteins`. The `\_balancecolumns` from \OpTeX/
   for splitting to two columns is used. We need to set `\_Ncols`, `\_dimen0`
   and `\_box6` before running `\_balancecolumns`. We need to insert
   `\vskip\splittopskip` because `\_balancecolumns` supposes that the typesetting point
   resides at the first baseline of the columns.\nl
   The final `\vskip` does \"raggedbottom". We need to add `1filll` in order
   to suppress the `\vfill` from the `\end` algorithm. We add `minus6pt`
   because the height of two columns can be by half-line higher than the
   insertion algorithm excepts (in the case with odd lines before
   splitting to the two columns).

   <chapter>:<verse> is or at the next page. The article is in two-columns

   a part, the height does not exceeds 2/3 of the page. But single two-column part
   can be higher.

   Then the number of columns `\_Ncols` is 2 times the number of calculated pages.
   The height of each two-columns part of the article is `\dimen0`.
   Finally we do re-boxing the output of `\_balancecolumns` in order to
   reach individual columns and create pairs of them by `\fornum` loop.

   \sec Inserting images over two pages
   %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
   We can insert an image at the bottom of the page which spans from even to
   odd page. The macro
   \`\insertSpanImage``{<Title>} [<label>] (<params>) {<image file>}` does it.
   The image is placed at the bottom of the pages using following rule:
   if the `\insertSpanImage` occurrs at the current page $c$ then
   \begitems
   * if $c$ is even and the image height fits to the current page then the
     image is inserted to pages $c$, $c+1$,
   * if $c$ is even and the image height doesn't fit to the current page then
     the image is inserted to pages $c+2$, $c+3$,
   * if $c$ is odd then the image is inserted to pages $c+1$, $c+2$.
   \enditems
   The macro `\insertSpanImage` saves the image in the box `\.spanpicbox`.
   The `\_picwidth` of the image is calculated as 2*(`\_hsize`*<inner_margin>).
   I.e. when we put the box to the page firstly
   then only the left half of its size is printed.

   Next, \^`\insertSpanImage` checks if the current page is even. If it is true and
   if there is sufficient space `\pagegoal-\pagetotal` at the current page, the
   image is inserted to the current page using the `\.startinsertSpanImage`
   which runs `\.insertBot` in fact. The second part of the image is printed
   because `\_endoutput` (processed at the end of the output routine where
   first part of the image is inserted) runs `\.addpicbox`. The
   `\.addpicbox` runs second `\.insertBot` which is printed on the next
   page.

   If the current page is odd, then `\insertSpanImage` doesn't run `\.startinsertSpanImage`
   immediatelly, but `\_endouput` inserts first part of the image using
   `\.inspicbox` which is equal to `\.inspicboxafter` in this case. It
   processes `\.startinsertSpanImage` which inserts the first part of the
   image on the next page (even) page.

   If the current page is even but the image cannot fit to the current page
   then the delay using `\_endoutput` is activated too. But the
   `\.ispicboxafter` checks that the current page is even and it does nothing in
   this case. Next page is ofdd, so `\.ispicboxafter` invoked by next
   `\_endinput` inserts the first part of the image which will be printed on
   the next (even) page.

   The following macros \`\Cite`, \`\insertCite` and \`\swapCites` are used for
   insertion of citations to the two-cloumn printed articles.
   The \^`\Cite` `<label>{<text>}` simply saves the <text> to the macro
   `\c!<article-num>!<label>`.
   The \^`\insertCite` `<label><feft-or-right>` inserts the citation declared
   by \^`\Cite` `<label>` to the text using `\vadjust`. The variant `\left` and
   `\right` is processed or ignored. This depends on the parity of the
   current page, which is restored from `.ref` file and saved to the macro
   `\cp!<article-num>!<label>`.
