% \section{Introduction}
%
% The package |fancytooltips| is a package for \LaTeX. The pdf can be
% created by pdflatex or by latex + dvips +
% AdobeDistiller\footnote{not free ps2pdf} + Adobe
% Acrobat\footnote{not free Adobe Reader.}. It allows to create
% tooltips in a similar way like |cooltooltips| package, but the
% tooltip is a page from another PDF file. In this way you can use
% mathematics, pictures and animations in your tooltips. The
% resulting PDF file can be used also with free Abobe Reader.
%
% The \color{black}tooltips are activated by clicking the active area
% on the screen and deactivated after closing page or by moving mouse
% outside the link. You can try the links \tooltip{here}{1}
% (Einstein's formula) and also \tooltipanim{here}{2}{7} (animation --
% numbers from 1 to 6).  You have to use the free Adobe Reader or
% nonfree Adobe Acrobat to see the effect (xpdf, evince and others
% fail to work with JavaScripts). For more examples how the
% presentation may look like see the |example.pdf| and
% |example-min.pdf| files in the |examples| subdirectory.
%
% The buttons are created using |eforms.sty| which is a part of
% AcroTeX bundle.
%
% \section{Usage}
% \subsection{The file with tooltips} 
% The file with tooltips is an ordinary pdf file, one tooltip per
% page, tooltips should be in the top right corner at the page, in a
% colored box and the rest of the page should be transparent. If you
% consider to use |movetips| option (see below), then every page
% should have the dimensions equal to the dimensions of the colored
% box with tooltip\footnote{Look at the files \texttt{tooltipy.tex} and
%   \texttt{tooltipy.pdf} from |examples| subdirectory for a simple example
%   how to meet this condition under pdf\LaTeX}. We also provide
% simple cross referencing mechanism to reffer to the tooltips. If the
% pdf file is created by \LaTeX, \DescribeMacro{\keytip} you can
% define keywords to reffer to the pages using |\keytip| command.
% Simply put |\usepackage[createtips]{fancytooltips}| into preamble
% and write \texttt{\string\keytip}\marg{foo} in document. This writes
% information about keyword \meta{foo} and the pagenumber into file
% |fancytips.tex|.
%
% \subsection{The file with presentation -- pdf\LaTeX users}
% In the file with presentation, the user is responsible
% \begin{itemize}
% \item input either |color| or |xcolor| package in the
%   preamble
% \item \LaTeX{} the file two times (we write some macros into |aux|
%   file).
% \end{itemize}
% This is not comfortable for the user, but everybody uses different
% set of packages and from this reason, this part is left to the user.
% (And among others, the |color| or |xcolor| package is probably
% inputted by the package which is used to build the presentation.)
%
% \DescribeMacro{filename option} To input the tooltips from file
% \meta{foo.pdf} call the package with |filename| option:
% |\usepackage[filename=foo]{fancytooltips}|.
%
% \DescribeMacro{movetips option} By default, tooltip appears in the
% top right corner of the page (use View--PageLayout-Single Page in
% your Adobe Reader, please). If the option |movetips| is used, then
% tooltip appears close to the mouse pointer. More preciselly, tooltip
% appears with left down corner at the mouse position, if there is
% enough place. If not, tooltip appears with right down corner at the
% mouse position. Finally, the tooltip is shifted down to fit the
% page, if nesessary\footnote{This option works in this way if every
%   page of the file with tooltips has dimensions of the box with
%   tooltip.  See the \texttt{examples} subdirectory.}.
%
% \DescribeMacro{mouseover option} If you use |mouseover| option, then
% tooltip appears if you move the mouse pointer to the active area (no
% clicking is necessary).
%
% \DescribeMacro{\tooltip} The user can put the tooltip into her or
% his presentation using the command
% \texttt{\string\tooltip}{\marg{stuff}\marg{keyword-or-pagenumber}}
% where \meta{stuff} is the printed text in \meta{tooltipcolor} color
% and \meta{keyword-or-pagenumber} is either the pagenumber of the
% tooltip in the external file or the keyword defined by |\keytip|
% command.  \DescribeMacro{\TooltipExtratext} The printed text
% \meta{stuff} is followed by |\TooltipExtratext| command. The default
% value is small blue soap in a box with zero dimensions, as you have
% seen in the second paragraph of this documentation. There is a
% package option |noextratext| which defines |\TooltipExtratext| to be
% empty. \DescribeMacro{noextratext option}
% 
% \DescribeMacro{\tooltipanim} The user can put a series (animation) of
% tooltips into the presentation by using
% \texttt{\string\tooltipanim}\marg{stuff}\marg{start}\marg{end}
% command, where \meta{start} and \meta{end} are keywords defined by
% |\keytip| command or page numbers.  \DescribeMacro{\delayinterval}
% The delay between two frames is |\delayinterval| milliseconds. The
% default value is 200, you can change it by command
% |\def\delayinterval{100}|.
%
% The file |example.tex| from |exmaples| subdirectory shows, how to
% redefine these macros to gain different behavior, see the demo file
% |example.pdf|.
%
% \subsection{Changes for dvips users}
% dvips users have to specify option |dvips| in |fancytips| package.
% \DescribeMacro{pages option} They have to use also a |pages| option
% with the number of pages in the PDF file with tooltips. You have to
% call the package by
% something like this:\\
% |\usepackage[dvips,filename=tooltipy,pages=27]{fancytooltips}|
% 
% You have to |latex| (two times) and |dvips| your file first.  This
% produces |filename.ps| and |Tooltipsdljs.fdf| files. Distill the pdf
% file into |filename.pdf| and open this file by Adobe Acrobat - this
% imports macros from |Tooltipsdljs.fdf| file.  In Acrobat's
% JavaScript console (|Crtl+J|) run (|Ctrl+Enter|) the command
% |ImportTooltips();| which is defined for the document and it creates
% invisible buttons on the first page, imports icons (the file with
% icons specified as \meta{filename} parameter when loading
% fancytooltips must be in working directory) and returns 1. Then
% save the file under another name.
%
% \section{Known problems}
%
% The package works only with the last |eforms.sty|, version
% 2006/10/03 v1.0a. You can download this version from www.arotex.net
% site. The version on CTAN and in MikTeX repositories is old and this
% package does not work with this old version.
