%    \section{Introduction}
%    This package addresses the issue of a poor-man's database. Educators who use {\LaTeX} to construct
%    exams and homework sometimes have a collection of problems. Each problem is in its own TEX file. The educator
%    creates a document and \cs{inputs} several of these packaged questions. This package attempts to provide some
%    ``user interface'' to the questions and provides a mechanism of selecting which questions are to be included in the
%    document.
%
%\paragraph*{What does this package do?} For a document that inputs content using the {\LaTeX} command \cs{input},
%the same content can be input using the command \cs{pmInput} (capitalized). When content is input by \cs{pmInput}, a check
%box is created in the margin at the insertion point of the content. The check boxes so created can be checked or cleared.
%When the user clicks on push button provided by this package, a list of all \emph{selected} \cs{input} statements are listed
%in the JavaScript console. This list can then be copied and pasted into another document the author is developing. If you
%\uif{Ctrl+Click} on a check box, the associated content is opened in the default TEX editor. In this way, the document author
%can see a typeset of the content and decide whether the content should be included in the developing document.
%
%\paragraph*{The DB stage:} When you have a collection of questions (or content) in various files and want to use
%this package to \cs{input} them into your document, the following comments are apropos:
%
%\subparagraph*{PDF creators:} Any PDF creator current in the {\LaTeX} world is valid for use with this package.
%
%\subparagraph*{PDF viewers:}
%The ideal viewer is \app{Acrobat}, however, \app{Adobe Reader} and \app{PDF-XChange Editor} can also be used.
%In the case of \app{Adobe Reader}, there is an annoying security dialog box that appears each time you use the
%\uif{Ctrl+Click} feature of the check box; the \uif{Ctrl+Click} feature does not WORK with \app{PDF-XChange Editor}.
%
%\paragraph*{The production stage:} After the document has been assembled (using \pkg{pmdb}), and you build your final document
%(perhaps an \pkg{exerquiz} quiz), the end user can use an appropriate PDF reader. If an \pkg{exerquiz} quiz is used, then
%a minimum of \app{Adobe Acrobat Reader} is required.

%  In version dated 2021/01/03, we introduce a button to edit the resource directly in the default application.
%  If can be turned on with \DescribeMacro\editSourceOn\cs{editSourceOn} and off again with \DescribeMacro\editSourceOff
%  \cs{editSourceOff}. The default is off. These commands can be placed
% anywhere in the document and affect all subsequent insertions of \cs{cbSelectInput}.

%    The button to show the current referenced content in the default application.

%\DescribeMacro\cbSelectInput\nmpsep{\darg{\ameta{path}}} creates a check box with a tool tip of \ameta{path}
%The mouse up action \cs{ccBoxMU} fixes up relative paths, and defines a \uif{Ctrl+Click} action. When the check box
%is so clicked, the \ameta{path} is opened in the default browser. The \ameta{path} can be relative or absolute.
%This command is used within \cs{insertCkBx}; its \ameta{path} argument is passed to it from \cs{insertCkBx}.
