-% \begin{abstract}
-% |bitfield| provides an environment and commands for drawing
-% bit field diagrams, which can be used to describe instruction sets,
-% object code formats, and other bit field based data structures.
-% \end{abstract}
-%
-% \section{User interface}
-%
-% \subsection{Bit field environment}
-%
-% \DescribeEnv{bitfield}
-% Bit field diagrams are drawn in the |bitfield| environment, which
-% takes two arguments. The first, optional argument gives the width of
-% a word (default 4in), and the second the number of bits per word.
-% Each word comprises a number of bit fields, and the words are drawn
-% as a column. Words are ended by |\\|.
-%
-% \DescribeEnv{xbitfield}
-% The |bitfield| environment is actually written in terms of the
-% |xbitfield| environment, which has an extra parameter (the second),
-% giving the left and right margin (the |bitfield| environment uses
-% |\layersize|).
-%
-% \DescribeMacro{\bits}
-% The basic bit field command is |\bits|.
-% |\bits[|\textit{style}|]{|\textit{label}|}{|\textit{bits}|}{|\textit{contents}|}|
-% draws a bit field with the given label, number of bits and contents.
-% The optional argument gives the bit field style, which is a string of
-% flag letters. |d| draws the box dashed, useful for indicating
-% optional structures. and |r| puts the label text in a rule
-% which spans the box.
-%
-% \DescribeMacro{\bitstack}
-% To indicate plurals, for example, where a particular word or data
-% structure may be repeated, |\bitstack| can be used, which produces
-% the appearance of a stack of bit fields. It may only be used once
-% per word (i.e.\ once per line).
-% |\bitstack[|\textit{style}|]{|\textit{label}|}{|\textit{bits}|}{|\textit{contents}|}|
-% draws a stack of width \textit{bits}. The first three arguments are
-% as for |\bits|. The \textit{contents} will typically be a |\bits|
-% command; |\bitstack| itself only draws the stack effect. The
-% enclosed |\bits| should not have a label.
-%
-% For technical reasons, the first bit field on each line is
-% |\fboxrule| narrower than it should be; this should not be
-% noticeable for typical values of |\fboxrule|. (See
-% section~\ref{fudge} for the full story.)
-%
-% \subsection{Alternatives}
-%
-% \DescribeMacro{\bitsub}
-% Sometimes a data structure may have its bit fields divided in
-% different ways according to circumstances, or a particular field may
-% hold one of a small range of values. To show these sorts of
-% alternatives, you can use |\bitsub|, which produces a sub-column of
-% bit fields, vertically centred on the current word.
-% |\bitsub[|\textit{style}|]{|\textit{label}|}{|\textit{bits}|}{|\textit{contents}|}|
-% makes a sub-column of width \textit{bits}. The first three arguments
-% are as for |\bits|, and \textit{contents} is the series of bit
-% fields to go in the column, as if in a |bitfield| environment,
-% separated by |\\|.
-%
-% \DescribeMacro{\bitsubspaced}
-% |\bitsub| draws the alternative bit fields contiguously; to make
-% room for a label on each bit field, use |\bitsubspaced|. 
-% |\bitsubspaced| is the same as |\bitsub|, except that the second
-% argument is omitted; a label can be given as that of the top-most
-% bit field in the contents.
-%
-% \subsection{Helper commands}
-%
-% Some other commands are provided to help draw bit field diagrams.
-% \DescribeMacro{\bitdots} |\bitdots| draws a vertical ellipsis,
-% like |\vdots|, but centred on the column of words.
-% \DescribeMacro{\bittext} |\bittext{|\textit{text}|}| allows text
-% to be inserted between words in a column, adding appropriate
-% vertical spacing.
-%
-% \subsection{Style parameters}
-%
-% There are many style parameters that allow the layout of bit field
-% diagrams to be customised:
-%
-% \begin{itemize}
-% \item[]\hskip-\leftmargin
-% \DescribeMacro{\bitalign}
-%    |\bitalign| gives the alignment within the |bitfield|
-%    environment; defaults to |\centering|.
-% \item[]\hskip-\leftmargin
-% \DescribeMacro{\bitboxsep}
-%    |\bitboxsep| is the width of the left and right margins of the
-%    bit field box; defaults to |\fboxsep|.
-% \item[]\hskip-\leftmargin
-% \DescribeMacro{\bitboxdepth}
-%    |\bitboxdepth| is the depth of a bit field box; defaults to
-%    0.9ex. 
-% \item[]\hskip-\leftmargin
-% \DescribeMacro{\bitboxheight}
-%    |\bitboxheight| is the height of bit field box; defaults to
-%    3.2ex. 
-% \item[]\hskip-\leftmargin
-% \DescribeMacro{\bitskip}
-%    |\bitskip| is the vertical space between words; defaults to
-%    0.8ex. 
-% \item[]\hskip-\leftmargin
-% \DescribeMacro{\bitrule}
-%    |\bitrule| is the thickness of the label rule; defaults to
-%    |\fboxrule|.
-% \item[]\hskip-\leftmargin
-% \DescribeMacro{\bitlabellift}
-%    |\bitlabellift| is the lift of the label above the top of
-%    the box; defaults to 0.4ex.
-% \item[]\hskip-\leftmargin
-% \DescribeMacro{\bitruleheight}
-%    |\bitruleheight| is the height of the label rule above the
-%    baseline (top of the box); defaults to 0.6ex.
-% \item[]\hskip-\leftmargin
-% \DescribeMacro{\bitruleendlift}
-%    |\bitruleendlift| is the height of the ends of the label
-%    rule above the baseline; defaults to 0.2ex.
-% \end{itemize}

-% \section{Example}
-%
-% Here is an example showing most of the features of the |bitfield|
-% package:
-%
-% \begin{center}
-% \begin{bitfield}{32}
-% \bits{31}{1}{s}
-% \bits{30 \hfill 23}{8}{eeeeeeee}
-% \bits{22 \hfill 0}{23}{mmmmmmmmmmmmmmmmmmmmmm} \\

-% \bits[r]{}{8}{fixed}%
-%   \bitsubspaced{8}{\bits{}{8}{optional 1}\\\bits{}{8}{optional 2}}\\
-% \end{bitfield}

-% \subsection{Internal commands}
-%
-% Some internal helper commands are defined first.
-%
-% \begin{macro}{\bitdec@destyle}
-% |\bitdec@destyle| decodes a style string. Three commands are set
-% up: |\bitb@xcmd|, to draw the box, |\bitst@ckcmd|, to draw a bit
-% stack box, and |\bitl@belcmd|, to draw a label.
-%
-%    \begin{macrocode}

-    \renewcommand{\bitst@ckcmd}{\lbox}%
-    \renewcommand{\bitl@belcmd}{\bitpl@inlabel}%
-%    \end{macrocode}
-%
-% The style string is then scanned, and the commands altered
-% accordingly. The code here is adapted from that for the
-% picture version of |\makebox|.
-%
-%    \begin{macrocode}
-    \@tfor\reserved@a :=#1\do{%

-%    \end{macrocode}
-% \end{macro}
-%
-% \begin{macro}{\bitle@der}
-% |\bitle@der| produces the middle sections of label rules.
-%
-%    \begin{macrocode}
-\newcommand{\bitle@der}{%

-%    \end{macrocode}
-% \end{macro}
-%
-% \begin{macro}{\bitpl@inlabel}
-% |\bitpl@inlabel| draws a label over a bit field box. The first argument
-% gives the width of the label, and the second the label text. The
-% label text is set at |\footnotesize|.

-% \begin{macro}{\bitrulel@bel}
-% |\bitrulel@bel| draws a label with a rule. The first argument gives
-% the width, and the second the text to go in the middle.
-%
-%    \begin{macrocode}
-\newcommand{\bitrulel@bel}[2]{%

-% \end{macro}
-%
-% \begin{macro}{\bitl@bel}
-% |\bitl@bel| labels a bit field box. The first, optional, argument
-% gives an increment to add to the width of the label; this is used
-% for drawing stacks. The second argument gives the label text; the
-% third is the width of the box in bits, and the fourth is the box
-% itself.

-% \subsection{The environments}
-%
-% \begin{environment}{xbitfield}
-% The |xbitfield| environment provides the innards of the |bitfield|
-% environment. It provides a little extra customization, by means of
-% its second argument, which gives the left and right margin. The
-% other two arguments are as for the |bitfield| environment.
-%
-%    \begin{macrocode}
-\newenvironment{xbitfield}[3][4in]%
-%    \end{macrocode}
-%
-% First, |\bitw@dth| is calculated.
-%
-%    \begin{macrocode}
-    {\setlength{\bitw@dth}{(#1-#2*2)/#3}%
-%    \end{macrocode}
-%
-% The words are set in a minipage; the alignment is set according to
-% |\bitalign|, and inter-line spacing is turned off, so that only the
-% bit field layout parameters affect the result. |\endlinechar| is set
-% to $-1$ so that blank lines do not start a new paragraph. |\\| is
-% redefined to set |bitb@xfirst| to |true| as well as ending the
-% line, and |bitb@xfirst| is set to |true|.
-%
-%    \begin{macrocode}
-    \begin{minipage}{#1}\bitalign%
-    \offinterlineskip%
-    \endlinechar=-1%
-    \renewcommand{\\}%
-        {\par\vspace{\bitskip}\setboolean{bitb@xfirst}{true}}%
-    \setboolean{bitb@xfirst}{true}%
-    }%
-%    \end{macrocode}
-%
-% At the end of the environment, the minipage is closed, and
-% |bitb@xfirst| is set to |false| in case a |\bits| command is used
-% outside a |bitfield| environment (though that is not recommended).
-%    \begin{macrocode}
-    {\end{minipage}%
-    \setboolean{bitb@xfirst}{false}}
-%    \end{macrocode}
-% \end{environment}
-%
-% \begin{environment}{bitfield}
-% The |bitfield| environment simply invokes the |xbitfield|
-% environment with a margin of |\layersize|.
-%
-%    \begin{macrocode}
-\newenvironment{bitfield}[2][4in]%
-    {\begin{xbitfield}[#1]{\layersize}{#2}}%
