+
+  The boxhandler package
+  ======================
+
+This package provides a powerful, yet simple, interface for managing and
+manipulating the captions of boxed objects (e.g., tables and figures).  In
+addition to providing wide flexibility in the presentation style of the
+captions, this package, when used in combination with conditionally compiled
+LaTeX source codes, provides the ability to defer or preempt the presentation
+of figures, tables, and their associated lists.  In this way, one can, for
+example, by changing a single line of source code in the .tex file, change the
+output of LaTeX from a technical report with tables and figures interspersed
+in the text, to a journal-manuscript submission, with figures collected at the
+end of document, as well as lof and lot deferred or preempted.
+
+Run `boxhandler.ins' through LaTeX to produce boxhandler.sty 
+     from boxhandler.dtx.
+Run `boxhandler.dtx' through LaTeX to produce the documentation.

+% \begin{abstract}
+% This package was developed as a tool to manage the handling of \LaTeX{}
+% tables and figures, especially for conditionally compiled documents.
+% With these tools, not only can one conveniently define table and figure
+% captions with a wide variety of stylistic appearances, but one can
+% create a single \LaTeX{} document that can, with a single line change
+% in the source code, produce an output that has vastly different layout
+% from the baseline configuration, not only in terms of caption style,
+% but also in terms of the locations where figures, tables and lists
+% appear (or not) in the document.
+% \end{abstract}

+%
+% \section {Introduction}
+%
+% The commands described in the |boxhandler| style accomplish a number of
+% useful functions. Even without the use of a conditionally-compiled
+% document:
+% \begin{enumerate}
+% \item they allow the definition of figures and tables in compact routine
+% calls;
+% \item they retain wide flexibility in caption appearance \& table/figure
+% placement, through the use of simple setup calls.
+% \end{enumerate}
+% And for those who wish, from a single \LaTeX{} source file to
+% conditionally produce, on one hand, an internal technical report for
+% example, and on the other hand, a journal manuscript submission, this
+% style additionally allows:
+% \begin{enumerate}\setcounter{enumi}{2}
+% \item printing of figures \& tables to be [conditionally] deferred to later
+% in the document;
+% \item printing of lists (\textit{lof}, \textit{lot}) to be deferred later
+% in document; and
+% \item the preemptive cancellation of the \textit{toc}, \textit{lof}, and
+% \textit{lot}.
+% \end{enumerate}
+%
+% \section{Caption Style, Appearance and Box Placement}
+%
+% \subsection{Commands}
+%
+% This routine provides several routines for creating and tailoring the
+% appearance of captioned ``boxes'' (that is, figures and tables). 
+% They include:
+% \begin{verse}
+% |\bxtable[|\iq loc\uq|]{|\iq caption\uq|}{|\iq boxed object\uq|}|\\
+% |\bxfigure[|\iq loc\uq|]{|\iq caption\uq|}{|\iq boxed object\uq|}|\\
+% |\relaxCaptionWidth[|\iq len\uq|]|\\
+% |\limitCaptionWidth[|\iq len\uq|]|\\
+% |\constrainCaptionWidth[|\iq len\uq|]{|\iq len\uq|}|\\
+% |\captionStyle{|\iq offset type\uq|}{|\iq alignment type\uq|}|\\
+% \end{verse}
+% \DescribeMacro{\bxtable}
+% \DescribeMacro{\bxfigure}
+% The routines |\bxtable| and |\bxfigure| will actually produce the
+% complete table or figure, including caption.  In these two routines,
+% \iq loc \uq is an optional argument.  It can take on a value of: |h|,
+% |t|, |b|, or |p|.  This parameter refers to the same location argument
+% that goes with the \LaTeX{} float environments, to help \LaTeX{}
+% determine the placement of the item on your page. |h| is `here', |t| is
+% `top', |b| is `bottom', |p| is `page of floats'.  Omitting the first
+% argument just uses the default placement of the table and figure
+% environments.
+%
+% In |\bxtable| and |\bxfigure|, \iq caption \uq is the argument that
+% will eventually get passed on to the |\caption| call, after the routine
+% properly formulates it to match the desired figure/caption style.  The
+% caption may include |\label| identifiers to be referenced by the main
+% text.
+%
+% For |\bxtable|, the \iq boxed object \uq will typically be a tabular
+% box, though any \LaTeX{} boxed object will satisfy the routine.  Thus,
+% the difference between a |\bxtable| and a |\bxfigure| is largely a
+% semantic one.  The true difference between |\bxtable| and |\bxfigure|
+% in this regard is that the table caption is placed above the table,
+% whereas the figure caption is placed below it.  In addition, because
+% these routines make use of the standard |\caption| call within the
+% table and figure environments, calls to |\bxtable| and |\bxfigure| will
+% have their references automatically available to the List of Tables and
+% List of Figures, respectively.
+%
+% One of the differences between the |boxhandler| style and \LaTeX{}'s
+% default captioning environments is the default caption width.  Whereas
+% \LaTeX{} defaults to a full margin-to-margin caption width,
+% |boxhandler| defaults to a caption width equal to and aligned with the
+% width of the box being captioned. However, this caption-width default
+% within |boxhandler| can be changed to any arbitrary value, including
+% full-width, if desired.  The caption width, through the use of the
+% ``dead margin,'' can also be conveniently set to a fixed offset from
+% the table or figure width.  For example, all table captions could be
+% set to a width 1 inch larger than their associated tables.
+%
+% \DescribeMacro{\relaxCaptionWidth}
+% The routine |\relaxCaptionWidth| takes as its optional argument a
+% length dimension corresponding to the minimum allowed caption width,
+% even if an associated table or figure is of lesser box width.  While
+% this command might technically violate an organization's style
+% guideline, it allows one to avoid the situation of trying to assign a
+% caption to fit the width dimension of an extremely narrow table or
+% figure.  An example of this use is shown in Tables~\ref{tbl:narrow} and
+% \ref{tbl:wide}.  In the first table, the default minimum caption width
+% of 1~inch is retained, resulting in an unwieldy caption.  The second
+% table has been printed following an invocation of
+% |\relaxCaptionWidth[4.0in]|.  Using |\relaxcaption| with no argument
+% resets the minimum allowed caption width to the default value of 1
+% inch.
+%
+% \def\mycaption{A table which provides the secret entryword of the
+%                Halloween Ghost Club, assuming you can read the caption}
+% \def\mytabular{
+%   \begin{tabular}{\tbllayout}
+%     \hline
+%   Boohoocachoo\\
+%   \hline
+%   \end{tabular}
+%   }
+% \relaxCaptionWidth
+% \bxtable[t]{\mycaption\label{tbl:narrow}}{\mytabular}
+% \relaxCaptionWidth[4.0in]
+% \bxtable[t]{\mycaption\label{tbl:wide}}{\mytabular}
+% \relaxCaptionWidth
+%
+% If the minimum caption width is relaxed, the maximum allowed width
+% will be bumped up, if necessary, to remain greater than or equal to
+% the minimum allowed caption width.
+%
+% \DescribeMacro{\limitCaptionWidth}
+% The routine |\limitCaptionWidth| is analogous to |\relaxCaptionWidth|.
+% In this case, however, the maximum allowable caption width will be
+% defined.  If no argument is specified, the maximum allowed caption
+% width is reset to the default value, which is |\textwidth|.
+%
+% If the maximum caption width is constrained, the minimum allowed width
+% will be reduced, if necessary, to remain less than or equal to the
+% maximum allowed caption width.
+%
+% \DescribeMacro{\constrainCaptionWidth}
+% The minimum and maximum allowed caption widths may be simultaneously
+% specified with |\constrainCaptionWidth|.  The order of the two length
+% arguments is not important.  Omitting the optional argument will cause
+% both the min and max allowable caption widths to be fixed at the
+% specified value. In this manner, all caption widths will be set to this
+% single value, regardless of the size of the table or figure box it
+% describes.  Note that the use of |\constrainCaptionWidth| with a single
+% argument of |{\textwidth}| allows a full-width left-to-right margin
+% caption style to be achieved, if desired, as in Figure~\ref{fig:cnst}.
+%
+% \DescribeMacro{\captionStyle}
+% To understand the the figure and table caption style 
+% command, examine the caption styles in
+% Figures~\ref{fig:styo}--\ref{fig:styc}, in reference to the
+% boxed object with which they are paired.
+% |\captionStyle{|\iq offset type\uq|}{|\iq alignment type\uq|}| is a
+% compact way of specifying the caption style.  The first parameter
+% specifies the \textit{offset type} for long captions (since ``offset''
+% has no meaning for short captions).  It can take
+% the value of |o| for ``offset'' captions, such as that found in
+% Figure~\ref{fig:styo}, or |n| for ``nooffset'' captions, such as
+% that found in Figure~\ref{fig:styn}.
+%
+% \relaxCaptionWidth[\textwidth]
+% \captionStyle{n}{l}
+% \bxfigure[p]
+%   {Here is a full-width caption that takes up the full
+%   margin-to-margin dimension, regardless of how wide the boxed object
+%   it serves is. In this case, the caption is of the ``nooffset''
+%   variety\label{fig:cnst}}
+% {\framebox(260,40){Boxed Object: \tt\bs
+%   constrainCaptionWidth\lb\bs textwidth\rb}}
+% \relaxCaptionWidth
+% \captionStyle{o}{}
+% \bxfigure[p]{For ``offset'' captions, the ID label for the caption
+%            is offset to the left of the caption text\label{fig:styo}}
+%            {\framebox(180,40){Boxed Object: \tt\bs captionStyle\{o\}\{\}}}
+% \captionStyle{n}{}
+% \bxfigure[p]{For ``nooffset'' captions, the caption's ID label 
+%            is integrated into the caption text itself\label{fig:styn}}
+%            {\framebox(180,40){Boxed Object: \tt\bs captionStyle\{n\}\{\}}}
+% \captionStyle{}{l}
+% \bxfigure[p]{A short ``left''-aligned caption\label{fig:styl}}
+%            {\framebox(250,40){Boxed Object: \tt\bs captionStyle\{\}\{l\}}}
+% \captionStyle{}{c}
+% \bxfigure[p]{A short ``center''-aligned caption\label{fig:styc}}
+%            {\framebox(250,40){Boxed Object: \tt\bs captionStyle\{\}\{c\}}}
+%
+% The second parameter specifies the \textit{alignment type} for short
+% captions (since long captions are already fully aligned).  It can take
+% on the value of |l| for ``left''-aligned
+% captions, such as that in Figure~\ref{fig:styl}, the value |c| for
+% ``center''-aligned captions, such as that in Figure~\ref{fig:styc},
+% or the value of |r| for ``right''-aligned captions.
+%
+% The default style for this package is |\captionstyle{o}{l}|, or
+% ``offset''-style, ``left''-aligned captions.  This default caption
+% style is that displayed in Figures~\ref{fig:styo} and \ref{fig:styl},
+% for long and short captions, respectively.
+%
+% Note that caption alignment is not the same as caption justification.
+% Regardless of alignment, any caption of size sufficient to span the
+% full width of the caption box will be, by default, fully justified or
+% ``flushed'' within that caption box.  The captions in Figures~1 and 2
+% demonstrate this for both offset and nooffset caption types.  Text
+% justification can, however, be altered, as described later by the
+% |\CaptionJustification| parameter.
+%
+% \subsection {Additional User Parameters}
+%
+% In addition to the above commands, there are a variety of
+% lengths, counters, and modes, which may be set by the user,
+% to adjust the appearance of the caption
+% presentation.  The settings for all these parameters hold until and
+% unless subsequently reset by the user.
+%
+% \begin{verse}
+% |\setlength\captionGap{|\iq len\uq|}|\\
+% |\setlength\TableDeadMargin{|\iq len\uq|}|\\
+% |\setlength\FigureDeadMargin{|\iq len\uq|}|\\
+% |\setcounter{abovecaptionskipterm}{|\iq integer\uq|}|\\
+% |\setcounter{belowcaptionskipterm}{|\iq integer\uq|}|\\
+% |\let\CaptionFontSize |\iq fontsize, e.g., \uq|\small|\\
+% |\let\TableFontSize |\iq fontsize, e.g., \uq|\small|\\
+% |\def\LRTablePlacement{flushleft|\iq , \uq|center|\iq , or \uq
+% |flushright}|\\
+% |\def\LRFigurePlacement{flushleft|\iq , \uq|center|\iq , or \uq
+% |flushright}|\\
+% |\def\CaptionJustification{|\iq blank, \uq|\raggedright|\iq ,\\\uq
+% |                          \centering|\iq , or \uq
+% |\raggedleft}|\\
+% \end{verse}
+%
+% \DescribeMacro{\captionGap}
+% |\captionGap| defines the horizontal space
+% between the caption identifier (e.g., ``Figure~1.'') and the start
+% of the caption text itself.  Its default value is 1ex.
+%
+% \DescribeMacro{\TableDeadMargin}
+% \DescribeMacro{\FigureDeadMargin}
+% |\TableDeadMargin| and |\FigureDeadMargin| may be set to correct the
+% caption alignment for boxes that have a deadzone around their border.
+% Such dead space takes up boxwidth, but shows no visible data.  These
+% parameter values should be set to the left or right-hand dead  space
+% (assumed symmetric).  The default value for |\TableDeadMargin|, which
+% is suitable for \LaTeX{} generated tabular data, is 0.375em. The default
+% for |\FigureDeadMargin| is 0em.
+%
+% Additionally, these |\...DeadMargin| commands can be used to set the
+% box-size-to-caption-size disparity to any desired non-flush value.  As
+% an example, setting the value of |\FigureDeadMargin| to 0.5 inch will
+% make the figure captions always 1~inch smaller than the actual figure
+% size.  Setting it to $-0.5$ inch (\textit{a negative value!}) will make
+% the caption always 1 inch larger than the actual figure size (within
+% the error of the actual figure dead margin width, and subject to the
+% caption width min/max constraints).
+%
+% \DescribeMacro{\abovecaptionskipterm}
+% \DescribeMacro{\belowcaptionskipterm}
+% The quantities |\abovecaptionskipterm| and |\belowcaptionskipterm|
+% are related to
+% \LaTeX{}'s |\abovecaptionskip| and |\belowcaptionskip| functions,
+% defining the white- space above and below a caption.  Unlike the
+% corresponding \LaTeX{} functions, the parameters here are integers (not
+% lengths).  The terms represent multipliers of the \LaTeX{} length
+% measure |\p@| to be  used for the above- and below- captionskip. 
+% Their default values are 10 and 7, respectively.  These
+% values affect only captions that are created as part of bxtable and
+% bxfigure, and do not affect the |\abovecaptionskip| and
+% |\belowcaptionskip| definitions intrinsic to your default document
+% class.

+%          {\small (1em on left; 1em on right)}}
+% \end{picture}
+%
+% \DescribeMacro{\CaptionFontSize}
+% |\CaptionFontSize| defines the default size of the caption font, for
+% example \normalsize, |\large|, |\scriptsize|, etc.  The default value
+% is |\small|.
+%
+% \DescribeMacro{\TableFontSize}
+% |\TableFontSize| defines the default size of the font that appears
+% within the tables themselves.  Its default value is |\small|.
+%
+% \DescribeMacro{\LRTablePlacement}
+% \DescribeMacro{\LRFigurePlacement}
+% |\LRTablePlacement| and |\LRFigurePlacement| define the horizontal
+% placement of tables and figures with respect to the paper margins.  The
+% options for these two parameters include |{flushleft}|, |{center}| and
+% |{flushright}|.  The default is |{center}|.  This is different from the
+% ``left'', ``center'', and ``right'' alignment modes for captions,
+% which align short captions with respect to the boxed data.
+%
+% \DescribeMacro{\CaptionJustification}
+% By default, any caption that spans the entire width of the caption box
+% will be fully justified, or ``flushed'' with respect to the caption box
+% margins.  However, this behavior can be reset by redefining the
+% parameter |\CaptionJustification|.  For a ragged-right style within the
+% caption box, the definition should be set to |\raggedright|.  For the
+% brave and daring, |\raggedleft| and/or |\centering| can be explored.
+% Use |\def\CaptionJustification{}| to reset subsequent captions for full
+% flushing.
+%
+% Figure~\ref{fig:ragged} is provided to demonstrate some of these
+% features including:  caption justification (|\raggedright|), caption gap
+% (2.5~ex), caption font size (|\scriptsize|), LR figure placement 
+% (|flushright|), |abovecaptionskipterm| (3), and a value for
+% |\FigureDeadMargin| of 1em.

+% \section{Box and List Deferral/Preemption}
+%
+% \subsection{Description of Problem}
+%
+% For those using conditional compilation to create various versions of
+% the same basic document, the |boxhandler| package can provide great
+% utility.  The package has been designed to permit the deferral and
+% preemption of certain aspects of the document, such as figures, tables
+% and lists.  With such a capability, one has the capacity to not only
+% change the appearance of the alternate document version, but to
+% fundamentally change its layout too.  Table~\ref{tbl:cccode} provides a
+% simple example of how a document may be set up for conditional
+% compilation.
+% 
+% \setlength\TableDeadMargin{0.2em}\bxtable[h]
+% {Conditionally compiled \LaTeX{} code\label{tbl:cccode}}
+% {\begin{tabular}{c}\hline\\
+%   \ttfamily\parbox{4.15in}{
+%     \bs def\bs PREPARETYPE\lb\bs TECHRPT\rb\% choices: \bs TECHRPT or
+%     \bs MANUSCRIPT\\
+%     \bs newcommand\bs TECHRPT\lb\% class for ARL organizational tech rpts\\
+%     \% CONDITIONALLY COMPILED CODE FOR TECHRPT DOCUMENTS\\
+%     | |\bs documentclass\lb arlticle\rb\\
+%     \rb\\
+%     \bs newcommand\bs MANUSCRIPT\lb\% article-ized version of tech rpt.\\
+%     \% CONDITIONALLY COMPILED CODE FOR MANUSCRIPTS\\
+%     | |\bs documentclass[11pt]\lb article\rb\\
+%     | |\bs usepackage\lb TR2article\rb\\
+%     \% VARIOUS \bs MANUSCRIPT-SPECIFIC SETUP COMMANDS GO HERE\\
+%     \rb\\
+%     \bs PREPARETYPE\\
+%     \% LaTeX CODE \& DOCUMENT COMMON TO BOTH STYLES FOLLOWS HEREAFTER\\
+%   }\\
+% \hline\end{tabular}
+% }
+%
+% In this example, by setting the parameter in the first line of the
+% document to either |\TECHRPT| or |\MANUSCRIPT|, a different collection
+% of setup routines may be invoked for each particular document style.
+% This works great for such parameters that affect appearance, but not
+% placement of the \LaTeX{} entities.  For example, changing fonts,
+% margins, indents, etc. works fine with the conditional code shown in
+% Table~\ref{tbl:cccode}.  Even when a particular document class has
+% unique commands not found in other classes, a converter style file may
+% be created (such as |TR2article| in the Table~\ref{tbl:cccode} example)
+% to deal rationally with invocations of class-specific features.
+%
+% Where great difficulty arises is when the different styles desired of a
+% conditional compilation utilize fundamentally different layouts of the
+% principal document elements, such as figures, tables, and lists.  For
+% example, a technical report would have it's tables and figures
+% interspersed throughout the document, whereas the corresponding journal
+% manuscript submission might have tables and figures collected, one per
+% page, at the end of the document.  Whereas the report would have the
+% List of Figures (\textit{lof}) as part of the report's front matter,
+% the journal manuscript might request to have the \textit{lof} preceding
+% the figures located at the end of the manuscript.  A typical scientific journal
+% manuscript submission would not include a Table of Contents
+% (\textit{toc}), and perhaps not a List of Tables (\textit{lot}) either.
+%
+% Arranging for such options to unfold from a single input source file is
+% cumbersome without a special treatment.  The |boxhandler| style
+% provides routines to expedite and ease this cumbersome process.
+%
+% \subsection{Deferral and Preemption Commands}
+%
+% For figure and table deferral, and/or list deferral/preemption, the
+% following commands are available, all without arguments:
+%
+% \begin{verse}
+% |\holdTables|\\
+% |\holdFigures|\\
+% |\clearTables|\\
+% |\clearFigures|\\
+% |\killlistoftables|\\
+% |\killlistoffigures|\\
+% |\killtableofcontents|\\

+%
+% \DescribeMacro{\holdTables}
+% \DescribeMacro{\holdFigures}
+% |\holdTables| and |\holdFigures| are used to direct that any subsequent
+% invocations of |\bxtable| and |\bxfigure| merely store, rather than
+% store \& print the table or figure.  These |\hold...| commands would
+% typically be found in the conditionally compiled code for manuscripts,
+% for example.
+%
+% While the calculated width of the caption is saved at the time of call
+% to |\bxtable| and |\bxfigure| based upon the |boxtable| parameters at
+% the time of the |\bx...| call, the caption format (i.e., [no]offset,
+% center/left alignment, caption justification) is not set until the
+% figure/table is later printed as part of a |\clear...| command (the
+% logic here is that the caption style will be consistent through the
+% course of the document, thus alleviating the need to store this data
+% for each figure and table).
+%
+% \DescribeMacro{\clearTables}
+% \DescribeMacro{\clearFigures}
+% |\clearTables| and |\clearFigures| directs that any tables or figures
+% that have been stored, but not yet printed, be output at this point.
+% As mentioned above, the offset, alignment, and justification for
+% captions is set at the time of printing, not at the time of table or
+% figure creation.  The format for presenting tables and figures to be
+% cleared (i.e., one table/figure per page, vertically centered) can be
+% changed by renewing the commands |\theClearedTable| and/or
+% |\theClearedFigure|.  See the next section on Advanced Use for details.
+%
+% Note that if tables and figures have not been subject to a |\hold...|
+% command, the |\clear...| commands have no effect, since they affect
+% only those tables and/or figures which have not already been printed.
+% Thus, these commands would typically appear in the common document text
+% at the appropriate point where tables and figures, if previously held,
+% should be printed.  Note that, though commands have not been explicitly
+% provided to kill the printing of figures and tables, this can be
+% effectively accomplished by putting figures and/or tables on hold, and
+% then ending the document without having issued a corresponding
+% |\clear...| command.
+%
+% \DescribeMacro{\killlistoftables}
+% \DescribeMacro{\killlistoffigures}
+% \DescribeMacro{\killtableofcontents}
+% |\killlistoftables|, |\killlistoffigures| and |\killtableofcontents|
+% direct that any subsequent calls to print the respective list be
+% ignored and that the list be discarded.  This action cannot later be
+% undone with a |\hold...| command.  These commands would typically
+% appear in the conditionally compiled region of the document.
+%
+% \DescribeMacro{\holdlistoftables}
+% \DescribeMacro{\holdlistoffigures}
+% |\holdlistoftables| and |\holdlistoffigures| direct that calls to print
+% the particular list cited be deferred until a later invocation of the
+% corresponding |\clear...| command.  Note that a call to |\clearTables|
+% and |\clearFigures| will also clear the corresponding list first, if it
+% has been subject to a |\hold...| command (but not a |\kill...|
+% command).  These |\hold...| commands would typically appear in the
+% conditionally compiled region of the document.
+%
+% \DescribeMacro{\clearlistoftables}
+% \DescribeMacro{\clearlistoffigures}
+% |\clearlistoftables| and |\clearlistoffigures| clear the cited list
+% (i.e., those lists currently ``on hold'').  No list will be
+% printed if:  the |\listoftables| or |\listoffigures| command hadn't
+% earlier been invoked; if it had already been printed out because it
+% hadn't been subject to a hold; or if the list had previously been
+% killed. Note: calls to |\clearTables| or |\clearFigures| automatically
+% causes a call to |\clearlistoftables| or |\clearlistoffigures|,
+% respectively.  Therefore, these particular calls are only needed
+% explicitly in your \LaTeX{} document if it is desired to clear the list
+% well in advance of the associated tables or figures.
+%
+% With the deferral and preemption commands now described, we show how
+% they might be used to complete the multi-mode \LaTeX{} document stencil
+% that was first laid out in Table~\ref{tbl:cccode}.  To see this, refer
+% to Table~\ref{tbl:bxcode}.  The document is created with |\bxtable| and
+% |\bxfigure| calls dispersed throughout text, and nominally asks for the
+% \textit{toc}, \textit{lof}, and \textit{lot} to be printed at the
+% beginning of the document.  When |\PREPARETYPE| is defined as
+% |{\TECHRPT}|, this is exactly how the document unfolds.

+% However, by merely defining |\PREPARETYPE| as |{\MANUSCRIPT}|, the
+% \textit{toc} and \textit{lot} will be killed, preempting subsequent

+% |bxtables| and |bxfigures| are invoked, they will be created and
+% stored, but not printed.  At the very end of the document, all the
+% tables will first be cleared, one per page, vertically centered. The
+% call to |\clearFigures| will then clear the \textit{lof} on a new page,
+% and finally clear all the figures in a similar manner.

+% Additionally, there are certain lower level, yet accessible, counters,

+% possible to get into difficulty if not thinking through their use
+% thoroughly.  Pitfalls will be laid out, where known.  These accessible
+% hooks into the inner workings of the |boxhandler| package include:

+% \end{verse}
+%
+% \DescribeMacro{TableIndex}
+% \DescribeMacro{FigureIndex}
+% \DescribeMacro{TableClearedIndex}
+% \DescribeMacro{FigureClearedIndex}
+% To keep track of tables and figures as they are created, the counters
+% |TableIndex| and |FigureIndex| are used.  To keep track of how many
+% tables and figures have already been printed, |TableClearedIndex|, and
+% |FigureClearedIndex| are used.  The appropriate index is incremented
+% whenever a table or figure is created or cleared.  These index counters
+% are also used as part of the naming convention employed by the
+% |\StoreTable| and |\StoreFigure| commands, to be subsequently
+% described.
+%
+% \DescribeMacro{promptTablesFlag}
+% \DescribeMacro{promptFiguresFlag}
+% The counters |promptTablesFlag| and |promptFiguresFlag| are used as
+% binary switches to determine whether calls to |\bxtable| and
+% |\bxfigure| result in the prompt display (1) or deferred display (0) of
+% the table or figure.  The |\holdTables| and |\holdFigures| commands
+% change these switches to their `0' state.  Any significant use of these
+% switches to achieve the printing of latter tables/figures prior to the
+% clearing of earlier ones will require the rewrite, by the user, of the
+% |\clearTables| and |\clearFigures| commands, since these |\clear...|
+% macros were written using a first-in-first-out (FIFO) methodology.
+%
+% \DescribeMacro{\StoreTable}
+% \DescribeMacro{\StoreFigure}
+% The macros |\StoreTable| and |\StoreFigure| use the same form of
+% caption and data arguments as |\bxtable| and |\bxfigure|.  In fact, the
+% |\bx...| commands call upon the |\Store...| macros.  The difference
+% is that the |\StoreTable| and |\StoreFigure| macros will save the
+% boxed object without printing it, regardless of whether a |\hold...|
+% command has been issued.  The saved information will consist of three
+% pointers necessary to recreate the table or figure.  These pointers
+% will be named according to |boxhandler|'s internal naming convention.
+%
+% At this point, it is worth noting the naming convention of the pointers
+% used by |boxhandler| to store the variables for figures and tables.
+% The saved information resulting from a |\StoreTable| or |\StoreFigure|
+% command will consist of a pointer to a saved box, a pointer to the
+% caption text, and a pointer to the calculated width of the caption box
+% (based on the state of the |boxhandler| parameters at the time of the
+% function call).
+%
+% The counters |TableIndex| and |FigureIndex| are used to create a unique
+% part of these pointer names, in the form of |\roman{|\iq
+% indexname\uq|}|.  Saved box pointers have the prefix |tbl-| or |fig-|,
+% saved caption pointers have the prefix |tblcap-| or |figcap-| and
+% caption-width pointers have the prefix |tblcapwdth-| and |figcapwdth-|.
+% Thus, for example, the fourth invocation of |\bxtable| or |\StoreTable|
+% will create an sbox named |\tbliv| that is used to store the boxed
+% (e.g., tabular) data, a pointer |\tblcapiv| that is used to store the
+% caption text, and a length pointer |\tblcapwdthiv| that stores the
+% value of the calculated caption width.  When avoiding creative
+% programming, the pointer index (e.g., `iv' in this example) will
+% correspond to the actual Table or Figure number (i.e., `4') appearing
+% in the caption ID label.  However, it is wise to remember,
+% \begin{enumerate}
+% \item when creating tables or figures outside of the |boxhandler| style;
+% \item when bypassing the |\Store...| commands and going straight to the
+% lower level |\SaveCBox| command; or
+% \item when using the |\Recite...| commands to print multiple occurances
+% of a box;
+% \end{enumerate}
+% that the internal numbering of |boxhandler| tables and figures will
+% likely be out of syncronization with the Table and Figure counters.
+%
+% \DescribeMacro{\SaveCBox}
+% The low-level routine which saves a ``captioned box'' is called
+% |\SaveCBox|.  As its arguments, it follows the form of the \LaTeX{}
+% |\sbox| command: it takes a new command name and the boxed object as
+% its parameters.  This is the routine called by the |\Store...| commands
+% with a command argument something like |\tbliv| or |\figiii|, for
+% example.  You are, however, free to pass your own command names to this
+% routine, so as not to conflict with the names autogenerated by the
+% |\Store...| commands.  Keep in mind that calls to |\SaveCBox| will not,
+% by themselves, increment |TableIndex| or |FigureIndex|, and will not be
+% tracked by the |\clear...| commands.
+%
+% \DescribeMacro{\DeadMargin}
+% \DescribeMacro{\CaptionBoxWidth}
+% In addition to saving the boxed object in the specified command bin,
+% the width of the associated caption is calculated, based upon the
+% prevailing |boxhandler| parameters at the time of call.  One such
+% parameter that is used to calculate the caption width, is the dead
+% margin.  |\SaveCBox|, being a low-level routine, is used for both
+% tables and figures.  As such, the appropriate variable to set, in order
+% to define the dead margin is the generic length |\DeadMargin|,
+% regardless of whether the call is to save a figure or a table box. The
+% calculated caption width is stored in the length variable
+% |\CaptionBoxWidth|.  This length variable is ephemeral, being updated
+% with each new figure or table generated, and so it is up to the user to
+% save the value of |\CaptionBoxWidth| somewhere else if it is to be used
+% to later define a recited box's caption width.  Likewise, while
+% |\SaveCBox| does not even deal with the box's caption text per se, it
+% is the user's responsibility to save the actual caption somewhere, for
+% later recitation.
+%
+% \DescribeMacro{\ReciteTable}
+% \DescribeMacro{\ReciteFigure}
+% Reciting stored tables or figures is accomplished by way of
+% |\ReciteTable| and |\ReciteFigure|.  As the [optional] first of their
+% four arguments, they take the location directive for placement on the
+% page (e.g., |h|, |t|, |b|, or |p|).  Both the caption and the caption
+% width arguments may be specified directly, or indirectly by way of a
+% stored string and length variable, respectively.  The command argument
+% to these macros must be the bin for the saved box object that
+% constitutes the actual table or figure data.
+%
+% If one desires, the |\Recite...| commands may be used repeatedly to
+% print a given table or figure multiple times.  However, any |\label|
+% associated with the [repeatedly recited] caption will be reassigned to
+% the most recent invocation of the |\Recite...| call.  Thus, references
+% to the table or figure number by way of a |\ref| call are likely to
+% produce an undesired result, if a given table or figure is recited
+% multiple times.
+%
+% \DescribeMacro{\theClearedTable}
+% \DescribeMacro{\theClearedFigure}
+% Finally, two very useful routines to be familiar with are the
+% |\theClearedTable| and |\theClearedFigure| macros.  These are the
+% routines which are repeatedly called by |\clearTables| and
+% |\clearFigures|, respectively, to print out all tables and figures
+% which have been ``on hold.''  The manner in which |boxhandler| clears
+% them is one per page, vertically centered.  It is easy to envision
+% applications in which the method of clearing would take on a different
+% appearance than this.  To change the appearance by which tables and/or
+% figures are cleared, these commands need to be redefined by the user by
+% way of a |\renewcommand|.  For reference, the |\theClearedTable|
+% command is defined by |boxhandler| as:
+%
+%| |\\
+%|\newcommand\theClearedTable[4][h]{|\\
+%|  \vspace*{\fill}|\\
+%|  \ReciteTable[#1]{#2}{#3}{#4}|\\
+%|  \vspace*{\fill}|\\
+%|  \clearpage|\\
+%|}|\\
+%
+% As one can see, |\theClearedTable| is a call to |\ReciteTable| that is
+% surrounded by the code necessary to place the table recitation at the
+% desired location upon the page.  |\theClearedFigure| is defined
+% analogously.  Modification of this layout should be straightforward for
+% the user.  For example, if it were desired to have two tables per page
+% during the clearing process, one might use the following renewal:
+%
+%| |\\
+%|\newcounter{toggle} \setcounter{toggle}{0}|\\
+%|\renewcommand\theClearedTable[4][h]{|\\
+%|  \addtocounter{toggle}{1}|\\
+%|  \ifnum \arabic{toggle} = 2 \setcounter{toggle}{0} \fi|\\
+%|  \ifnum \arabic{toggle} = 1|\\
+%|    \ReciteTable[t]{#2}{#3}{#4}|\\
+%|  \else|\\
+%|    \ReciteTable[b]{#2}{#3}{#4}|\\
+%|    \clearpage|\\
+%|  \fi|\\
+%|}|

+% \section {Vestigials}
+%
+% \DescribeMacro{\arltable}
+% \DescribeMacro{\arlfigure}
+% In order to retain backward compatibility with the predecessor to the
+% |boxhandler| package, the vestigial commands |\arltable| and
+% |\arlfigure| are defined in this package, and are equivalent to
+% |\bxtable| and |\bxfigure|, respectively.
+%
+% As an historical note, the genesis of the |boxhandler| package was a
+% requirement to comply with my organization's caption style (``offset''
+% style, ``left'' aligned) specified for its technical reports.  Various
+% kludges were out there to handle it, requiring a fair amount of
+% case-specific hand-holding and babysitting, depending on the specifics
+% of the figure/table box and the caption.  |boxhandler| was intended to
+% simplify and generalize the approach.
+%
+% The figure/table deferral features of |boxhandler| were borne of my own
+% laziness.  I just didn't relish keeping two different versions of the
+% same document up to date... one for my organization, and the other as a
+% manuscript for possible journal submission.  The |\bx...| commands
+% provided an easier ``hook'' through which to achieve the holding and
+% clearing of boxes than did any attempt to muck with the underlying
+% |Figure| and |Table| environments of \LaTeX{}.
+%
