%% == 'blog' Required ==
%% 'blogdot' is an extension of 'blog'
%% (but what about options? TODO):
\RequirePackage{blog}
%% == Size Parameters ==
%% \label{sec:dot-size}
%% I assume that it is clear what the following
%% six page dimension parameters
%% \begin{quote}
%% |\leftpagemargin|, |\rightpagemargin|,
%% |\upperpagemargin|,\\|\lowerpagemargin|,
%% |\typeareawidth|, |\typeareaheight|
%% \end{quote}
%% mean.
%% The choices are what I thought should work best
%% on my 1024$\times$600 screen (in fullscreen mode);
%% but I had to optimize the left and right margins experimentally
%% (with Mozilla Firefox~3.6.22 for Ubuntu canonical~-~1.0).
%% It seems to be best when the horizontal parameters
%% together with what the brouswer adds
%% (scroll bar, probably 32px with me)
%% sum up to the screen width.
\newcommand*{\leftpagemargin}{176}
\newcommand*{\rightpagemargin}{\leftpagemargin}
%% So |\rightpagemargin| ultimately is the same as
%% |\leftpagemargin| as long as you don't redefine it,
%% and it suffices to `\renewcommand' `\leftpagemargin'
%% in order to get a horizontically centered type area
%% with user-defined margin widths.---Something analogous
%% applies to |\upperpagemargin| and |\lowerpagemargin|:
\newcommand*{\upperpagemargin}{80}
\newcommand*{\lowerpagemargin}{\upperpagemargin}
%% A difference to the ``horizontal" parameters is
%% (I expect) that the position of the type area on the
%% screen is affected by |\upperpagemargin| only,
%% and you may choose |\lowerpagemargin| just large enough
%% that the next slide won't be visible on any computer screen
%% you can think of.
\newcommand*{\typeareawidth}{640}
\newcommand*{\typeareaheight}{440}
%% Centering with respect to web page body may work better on
%% different screens (2011/10/03), but it doesn't work here
%% (2011/10/04).
% \renewcommand*{\body}{%
% </head>\CLBrk
% <body \@bgcolor{\bodybgcolor} \@align@c>}
%% |\CommentBlogDotWholeWidth| procuces no \HTML\ code ...
\global\let\BlogDotWholeWidth\@empty
%% ... unless calculated with |\SumBlogDotWidth|:

%% == Finishing a ``Slide" and ``Restart" (Backbone) ==
%% \label{sec:dot-fin}
%% |\screenbottom{<next-anchor>}| finishes the current slide
%% and links to the <next-anchor>, the anchor of a slide opened by
%% \[`\startscreenpage{<style>}{<next-anchor>}'.\]
%% More precisely, the margin below the type area is that link.
%% The corner at its right is a link to the anchor to whose name
%% |\BlogDotRestart| expands.

%% The default for |\BlogDotRestart| is |START|---the title page.
%% You can `\renew'\-`command' it so you get to a slide
%% containing an overview of the presentation.
\newcommand*{\BlogDotRestart}{START}
%%
%% == Moving to Next ``Slide" (User Level) ==
%% \label{sec:dot-next}
%% |\nextscreenpage{<style>}{<anchor-name>}|
%% puts closing the previous slide and opening the next
%% one---having anchor name `<anchor-name>'---together.
%% <style> is for style settings for the next page,
%% made here for choosing between centering the page/slide content
%% and aligning it flush left.
\newcommand*{\nextscreenpage}[2]{%
\screenbottom{#2}\CLBrk
\hrule \CLBrk
\startscreenpage{#1}{#2}}
%% |\nextcenterscreenpage{<anchor-name>}| chooses centering
%% the slide content:

%% |\nextnormalscreenpage{<anchor-name>}| chooses flush left
%% on the type area determined by |\typeareawidth|:
\newcommand*{\nextnormalscreenpage}{\nextscreenpage{}}
%%
%% == Constructs for Type Area ==
%% \label{sec:dot-type}
%% If you want to get centered titles with \xmltagcode{h2} etc.,
%% you should declare this in `.css' files. But you may consider
%% this way too difficult, and you may prefer to declare this
%% right in the \HTML\ code. That's what I do! I use
%% |\cheading{<digit>}{<text>}| for this purpose.
\newcommand*{\cheading}[1]{\CLBrk\TagSurr{h#1}{\@align@c}}
%% |\begin{textblock}{<width>}| opens a |{textblock}|
%% environment. The latter will contain text that will be flush left
%% in a narrower text area---of width <width>---than the one
%% determined by |\typeareawidth|. It may be used on
%% "centered" slides. It is made for lists whose entries are
%% so short that the page would look unbalanced under a
%% centered title with the list adjusted to the left
%% of the entire type area. (Thinking of standard \LaTeX,
%% it is almost the `{minipage}' environment, however lacking
%% the footnote feature, in that respect it is rather
%% similar to `\parbox' which however is not an environment.)
\newenvironment*{textblock}[1]
{\startTable{\@width{#1}}\starttr\startTd{}}
{\endTd\endtr\endTable}
%%
%% == Debugging and `.cfg's ==
%% \label{sec:cfgs}
%% |\ShowBlogDotBorders| shows borders of the page margins
%% and may be undone by |\DontShowBlogDotBorders|:
\newcommand*{\ShowBlogDotBorders}{%
\def\maybe@blogdot@borders{rules="all"}}
\newcommand*{\DontShowBlogDotBorders}{%

%% %% 2011/10/14:

\def\maybe@blogdot@frame{\@frame@box}}
\newcommand*{\DontShowBlogDotFrame}{%
\let\maybe@blogdot@frame\@empty}
\DontShowBlogDotFrame
%% However, the rules seem to affect horizontal positions ...
%%
%% |\BlogDotFillText| is a dirty trick ... seems to widen
%% %% doc. extended 2011/10/13
%% the type area and this way centers the text on wider screens
%% than the one used originally. Of course, this can corrupt
%% intended line breaks.
\newcommand*{\BlogDotFillText}{% %% 2011/10/11

%% |\FillBlogDotTypeArea| fills `\BlogDotFillText' into the
%% type area, also as a link to the next slide. This may widen
%% the type area so that the text is centered on wider screens
%% than the one the \HTML\ page was made for. The link may serve
%% as an alternative to the bottom margin link
%% (which sometimes fails).
%% `\FillBlogDotTypeArea' %% 2011/10/22

%% |\FillBlogDotBottom| fills `\BlogDotFillText' into the
%% center bottom cell. I tried it before `\FillBlogDotTypeArea'
%% and I am not sure ...

%% |\DontFillBlogDotBottom|:
\newcommand*{\FillBlogDotBottom}{%
\let\BlogDotBottomFill\BlogDotFillText}

%% (2011/10/13)
\newcommand*{\DontFillBlogDotBottom}{\let\BlogDotBottomFill\@empty}
\DontFillBlogDotBottom
%% |\DontShowBlogDotFillText| makes `\BlogDotFillText' invisible,\\
%% |\ShowBlogDotFillText| makes it visible.
%% Until 2011/10/22, `\textcolor' ('blog.sty') used the
%% \xmltagcode{font} element that is deprecated.
%% I still use it here because it seems to suppress the
%% `hover' \acro{CSS} indication for the link.
%% (I might offer a choice---TODO)

%% As of 2011/10/21, 'texlinks.sty' provides

%% \[|\usemirrorctan|\quad \mbox{or}\quad |\usetugctan|.\]
%% This is preferable for an online version of the presentation.
%% In `dantev45.htm', this is used for example files.
%% When, on the other hand, internet access during the presentation is
%% bad, such example files may instead be loaded from the
%% ``current directory." \ |\usecurrdirctan| \ modifies `\ctanfileref'
%% for this purpose (i.e., it will ignore <path>):
\newcommand*{\usecurrdirctan}{%
\renewcommand*{\ctanfileref}[2]{%
\hnewref{}{##2}{\filenamefmt{##2}}}}
%% (Using a local \acro{TDS} tree would be funny, but I don't
%% have good idea for this right now. )

%% |\TryBlogDotCFG| looks for `blogdot.cfg',
%% \[|\TryBlogDotCFG[<file-name-base>]|\] %% \[...\] 2011/10/21
%% looks for `<file-name-base>.cfg'
%% (for recompiling a certain file):
