+% \section{Introduction}
+%
+% This {\LaTeX} code was originally part of the \textsf{exerquiz} package.
+% I decided it would be useful to others if I separated the two and make
+% the forms part of \pkg{exerquiz} into a separate package. The
+% \pkg{eforms} package is now a part of the \textsf{{Acro\TeX} eDucation
+% Bundle} and is called by \pkg{exerquiz}, but it is now a stand alone
+% package for others who may want to use PDF form fields and JavaScript
+% interactivity.
+%
+% \section{Package Options}
+%
+% The package options consist mostly of driver options.
+%
+% \subsection{Driver Options}
+%
+% The \textsf{web} package passes these driver options to \textsf{exerquiz}.
+% These options are needed is \textsf{exerquiz} is used without
+% \textsf{web}; in this case, the options below must explicitly included.
+% Set the driver dependent code for the |quiz| environments.

+% \subsection{Process Key-Value Pairs: Main Macro}\label{procArgs}
+%
+% The following macro, \cs{processAppArgs}, is due in part to
+% Dan Luecking. He proposed a very nice modification of my original
+% macros.
+%
+% The macro \cs{processAppArgs} takes an \textit{even} number of arguments; it
+% picks off two at a time, processes them, then picks off two more. The macro is meant to
+% process the optional arguments of a form field.
+%
+% All legal arguments (see \nameref{eformvariables} for a detailed
+% listing) are of the form \cs{\ameta{name}\darg{\ameta{arg}}}.
+% The macro takes two tokens at a time and constructs a macro
+% \cs{@eq\ameta{name}\darg{\ameta{arg}}}. Each of the macros \cs{@eq\ameta{name}} must be
+% defined. Such a macro defines another macro as follows
+% \cs{def\string\eq@\ameta{name}\darg{\ameta{arg}}}. For example if the user enters the token
+% pair |\RC{Users}|, \cmd{\processAppArgs} will construct
+% |\@eqRC|, with argument |{Users}|, this macro will be
+% executed, which expands to |\def\eq@RC{Users}|. The macro
+% \cmd{\eq@RC} may then be used within the construction of the
+% widget object.\medskip
+%
+% \noindent
+% \DescribeMacro\proccessAppArgs\hskip-\marginparsep\texttt{\darg{\ameta{key}}\darg{\ameta{value}}}
+% The macro takes pairs of key-values and constructs auxiliary macros, as described above.
+% It also does an addition operation for \textsf{\textbf{F}} (\cs{F}) and \textsf{\textbf{Ff}} (\cs{Ff}) entries.
+% Initially, it is called by |\processAppArgs|\texttt{\ameta{KV-pairs}}|\end\@nil|, \cs{end} being the detected
+% end of the stream of key-values.
+% \begin{macrocode}
+\let\ef@passedArgs\@empty
+\def\processAppArgs#1#2{%
+ \ifx\end#1% if #1=\end, #2=\@nil.
+ \let\ef@next\relax
+ \else
+% \end{macrocode}
+% If a token has a value of \cs{@empty} then it has been protected. It is skipped
+% and there is no user redefinition of that form field attribute allowed. Normally,
+% this is done for \cs{A} and \cs{AA} to prevent overwriting critical functionality.
+% \begin{macrocode}
+ \ifx#1\@empty
+% \@getCmdName{#1}\PackageWarning{eforms}
+% {Redefining the \eqbs\@CmdName\space key is not allowed}%
+ \def\ef@next{\processAppArgs}%
+ \else
+% \end{macrocode}
+% This is the user interface to the new optional argument of links and forms. If
+% the key is \cs{ui}, we pass its argument to |\setkeys{eforms}{#2}| to process
+% the key values of \textsf{xkeyval} style. If one of the keys is \texttt{annotflags} or
+% \texttt{fieldflags}, we pass those back to this stream to be analyzed the special cases
+% that follow for |\F| and |\Ff|.
+% \begin{macrocode}
+ \@getCmdName{\ui}\edef\arg@ui{\@CmdName}%
+ \@getCmdName{#1}%
+ \ifx\arg@ui\@CmdName
+ \@ifundefined{@equi}{\PackageError{eforms}%
+ {The user interface '\string\ui' is not defined!%
+ \MessageBreak Use the useui option of eforms
+ and try again}{I said, use the useui option of
+ eforms and try again!}}{}%
+ \def\ef@next{\setkeys{eforms}{#2}%
+ \processAppArgs\presets{\ef@passedArgs}}%
+ \else
+% \end{macrocode}
+% If current key is |\Ff|, we add its value to the current value of |\Ff|.
+% We basically are `or-ing' the new value with the old value in the bit field.
+% \begin{macrocode}
+ \@getCmdName{\Ff}\edef\arg@Ff{\@CmdName}%
+ \@getCmdName{#1}%
+ \ifx\arg@Ff\@CmdName % if \Ff, let's add arguments

+%
+% \subsubsection{Key-Value Definitions}
+%
+% The following definitions are used in various field templates.
+% Some convenience macros to help define the button attributes. The default
+% values are defined within the button macros themselves. Use these macros
+% within the optional argument of buttons and text fields to modify their
+% appearance.
+%
+% You'll notice, for example, the macros listed are not actually defined. For example
+% \cmd{\CA} is never defined, we define instead \cmd{\@eqCA} and \cmd{\eq@CA}.
+% The macros \cmd{\processAppArgs} treats \cmd{\CA} as a token, and prefixes with
+% \texttt{@eq} in a clever sort of way. It's done so that these macros cannot be used
+% outside the optional macro arguments of the button and text field macros.

+% Enhanced preview attempts to typeset into the document the value of the \cs{CA} key (for push buttons)
+% and the \cs{V} key for text fields and choice fields. This is useful for those using a non-conforming
+% PDF reader such as \app{sumatraPDF}. The enhanced preview is activated by expanding \cs{pmpvOn}
+% (\textbf{p}oor \textbf{m}an's \textbf{p}re\textbf{v}iew). A summary of the effects is describe below.\medskip
+% \begin{description}
+% \item[push buttons] The \cs{CA} entry is always
+% displayed; however, when the \emph{background color \emph{(\cs{BG})} is transparent}, the key-value entry generated by \cs{CA}
+% \emph{is removed}. This is to avoid two overlaying captions, one typeset into the document, the other part
+% of the button appearance.
+% \item[text and choice fields] The \cs{V} entry \emph{is set to empty} (when \cs{pmpvOn} is active),
+% but the value of the \cs{V} key is typeset into the document; this is to avoid two overlaying
+% values within the field. There is one special case, when the field is \emph{hidden}; in this case,
+% the value of the field is restored. Hidden text fields are used by the \pkg{acrotex} packages to hold
+% information that can later be retrieved.
+% \item[check box and radio button fields] These two cases are handled similar to \textbf{choice fields}. For these
+% types of fields, the values is typically a mark: a check, an cross, a star, and so on. For preview purposes,
+% \pkg{eforms} defines the declarative command \cs{pmpvMrk} that takes one argument, the mark to be used. The
+% package declares |\pmpvMrk{X}|, another good choice is |\pmpvMrk{$\checkmark$}|.
+% \end{description}
+% With respect to the enhanced preview, the local command \cs{tops}, used within the argument of \cs{V} or \cs{CA}, is
+% \cs{let} to \cs{texorpdfstring}. Use \DescribeMacro\tops\cs{tops} to offer an alternate text to the value of \cs{CA}
+% of \cs{V}. The \cs{V} key of radio button and check box fields do not handle the \cs{tops} command.
+%
+% For example,
+% \begin{quote}\small
+% |\pushButton[\CA{\tops{Tap Me}{Push Me}}]{pbFld}{}{11bp}|
+% \end{quote}
+% This button will preview with the caption as `Tap Me', but will appear within
+% a conforming PDF reader as `Push Me'; however, if the background color is
+% transparent (|\BG{}|), `Tap Me' will be the (typeset) caption even in a
+% conforming PDF reader. (This is to avoid overlaying captions.) It is
+% important\marginpar{\raggedleft \textbf{Important!}} to say that the final
+% document should be compiled with \cs{previewOff} and \cs{pmpvOff} opened in
+% \app{Adobe Reader} and saved to obtain proper appearances of the form
+% fields.
+%
+% The arguments of \cs{CA} and \cs{V} should be text, and must note have any {\TeX} formatting
+% like \cs{textbf}, \cs{textit}, and so on. That's not to say such formatting cannot be obtained.
+% There is an undocumented macro, \DescribeMacro\pmpvFmt\cs{pmpvFmt} that takes one argument, the argument being the
+% enhanced preview text. To illustrate its usage, we use the above example,
+% \begin{quote}\small
+% |\pushButton[\cmd{\let\pmpvFmt\textbf}|\\
+% \null\quad|\CA{\tops{Tap Me}{Push Me}}]{pbFld}{}{11bp}|
+% \end{quote}
+% Now, the enhanced preview will read `\textbf{Tap Me}'. Pass |\let\pmpvFmt\textbf| through
+% the \cs{cmd} key, the changes are local to the field.

+% \section{A User Interface to links and forms}
+%
+% Through the years, I've developed my own version of a ``key-value''
+% system, and this system works very well (see
+% Section~\ref{procArgs}, page~\pageref{procArgs}, for the main
+% macro); however, in a feeble attempt to make the system more user
+% friendly, I've incorporated an \textsf{xkeyval} system into the
+% \textsf{eforms} package. My old key-value system---which requires less
+% typing and, in my opinion, is easier to use---still works,
+% and the new one is just a user interface to the old system; parameters are
+% passed to the main processing macro, defined in Section~\ref{procArgs}.
+% \begin{macrocode}
+%<*userinterface>
+% \end{macrocode}
+% Let's bring in the \textsf{xkeyval} package.
+% \begin{macrocode}
+%\usepackage{xkeyval}
+% \end{macrocode}
+% The |\ui| interface is undefined if the \texttt{useui} option is not taken. We use this fact
+% to send a message to the user that using |\ui| most accompany the \texttt{useui}.
+% \begin{macrocode}
+\def\@equi#1{}
+% \end{macrocode}
+% The visibility of the border of a link depends on where the \texttt{colorlinks} option of hyperref has been
+% taken. If the author does not take \texttt{colorlinks}, a visible rectangle appears by default. By putting
+% \texttt{border=visible}, the author can override this behavior. If \texttt{colorlinks} option was taken, then the same
+% link has an invisible border by default. Again, the author can override this by putting \texttt{border=visible}.

+%\begin{verbatim}
+% lock={/Action/All} % lock all fields in the doc
+% lock={/Action/Include % lock all fields listed in Fields
+% /Fields [(field1)(field2)...]}
+% lock={/Action/Exclude % lock all fields not listed in Fields
+% /Fields [(field1)(field2)...]}

+%
+% Another option that is included in the Signed tab is titled ``This script executes
+% when field is signed.''
+%
+% This is an option that, through the user interface, is mutually exclusive from
+% locking fields. This option appears to be implemented through the format event.
+% Thus, to populate this option with JavaScript use \texttt{format}. For example,
+%\begin{verbatim}

+% \subsection{Specifying Actions}
+% Here, we offer up various common actions for a document author to choose from.
+%
+% The \texttt{goto}\IndexKey{goto} key is a combines \textsf{GoTo} and \textsf{GoToR} action. There are options for jumping to a page
+% with a particular view, a latex label, or a named destination.
+%
+% The goto key first calls |\setkeys{efgoto}{#1}|, which parses the parameters. Following the
+% reading of the parameters, we determined whether this is a GoTo or a GoToR request, whether
+% we are jumping to a page, a named destination or a latex label.
+%
+% Documentation for the parameters of \texttt{goto} follow this definition.
+%
+% Process the \texttt{goto} key using \pkg{conv-xkv}.
