+%
+% This self extracting documented file |lxfonts.dtx|, besides the |lxfonts.sty|
+% file,  produces the font description files necessary to use the LX fonts
+% in any document, specifically presentations, but not only. It documents
+% why they were made and the choices made in selecting which fonts to convert
+% to this style.
+%
+% These fonts should be useful for typesetting documents with T1 encoding (OT1
+% is also supported) and blends text and math fonts in the proper way; AMS fonts
+% are  supported. For legacy reasons the \LaTeX\ special symbol set is also
+% accordingly restyled. 
+%
+% \section{The LX fonts}
+% In the first eighties, when \LaTeX\ was conceived, Leslie Lamport  created
+% a stand alone program, or better, a mark-up \SliTeX\ format that
+% could be used in place of \LaTeX\ when it was necessary to create transparencies
+% for conferences, lectures, and presentations; when \LaTeXe\ was made available
+% in the early nineties, that set of mark-up macros and format did not exist
+% any more, and in its place there was the new class \pack{slides}.
+%
+% The processing of the source files was almost identical, although the new
+% class \pack{slides} had more typesetting power thanks to the \LaTeXe\ more
+% powerful macros.
+% 
+% Both processes produced printed documents that could be photocopied onto
+% methacrylate transparencies and used with overhead projectors.
+%
+% Since the advent of beamer projectors, that can operate directly from a
+% computer, and the availability of the \prog{pdfLaTeX} typesetting program,
+% a set of packages was made available to the \TeX\ community so as to
+% produce wonderful presentations, possibly together with their 
+% printed handouts, that quickly replaced the old and honorable \SliTeX\ 
+% format and the \pack{slides} class.
+% 
+% The fonts that Leslie Lamport had devised to use with \SliTeX\ and
+% \pack{slides} had a great advantage over the default \TeX\ system fonts,
+% namely the traditional Computer Modern ones, and, after the introduction
+% of the  new encoding T1, of the European Computer fonts and, later on,
+% of the Latin Modern vector fonts.
+%
+% It was \emph{legibility}.
+%
+% This advantage was obtained from the sans serif quotation fonts designed
+% by D.E.~Knuth himself; he used them to typeset the witty quotations at each 
+% chapter end of both his \TeX\ and \MF\ books.
+%
+% But these Knuthian fonts had a disadvantage: the capital `I' and the lower
+% case `l' were hardly distinguishable from one another and from the absolute
+% value vertical bar. Leslie Lamport solved in part this problem by changing
+% the sans serif `I' with a serifed one; this was fine most of the time, but
+% did not solve the similarity of the sans serif lower case `l' with the math
+% absolute value bar.
+%
+% Moreover when typesetting math in those old fashioned slides, only the
+% |operators| font was changed to a sans serif one, while the |letters| math
+% italics font, together with the other |symbols| normal and |largesymbols| large
+% symbol fonts remained the same; the result was that some math glyphs
+% obtained by juxtaposition of symbols coming from the operator font and
+% some other math font, resulted clearly inadequate.
+%
+% The solution of such problems consisted in redesigning the shape of the lower
+% case `l', so as to be more similar to an upright italic one, with a curved
+% bottom, and to restyle all the math fonts with the same graphic font settings
+% of the Lamport fonts, both in OT1 and T1 encoding, and in the math encodings
+% OML, OMS OMX, plus the Text Companion TS1 encoded fonts, the \AMS\ fonts and
+% the \LaTeX\ symbol fonts.
+% 
+% This is all what concerns these extended slide LX fonts; while doing this
+% extensions I had to change the metadescription of several glyphs, but the
+% overall work was not that complicated; it was just heavy because the large
+% number of fonts involved, and therefore the overall glyph number.
+% 
+% This package redefines both the text and math font families; checks if
+% the \AMS\ fonts have been called for, avoids to redefine the nice glyphs of
+% the \AMS\ collection with the \LaTeX\ symbol fonts, although it will
+% redefine the latter ones in case the user wants to use them, but did not
+% load the \AMS\ font collections.
+%
+% These settings are deferred at begin document time, so that the necessary
+% checks may be used after other fonts are possibly loaded.
+%
+% As a bonus the typewriter fonts are loaded in a scaled up version so that
+% their x-height matches the larger LX fonts. Such fonts are scaled 25\%
+% up so that the 8pt design size typewriter font x-height matches
+% the corresponding height of the LX fonts.
+%
+% These LX fonts are available in both vector and bitmapped form; I made the
+% whole work by working on the \MF\ source files; when I was satisfied with
+% the bitmapped fonts produced with \MF, I traced them by means of the
+% \prog{mftrace} program, by Han-Wen Nien­huys, and produced the .pfb files
+% containing the vector description of the glyphs. In order to use them
+% with \prog{pdfLaTeX} it is necessary to have available the .map file,
+% that I provided as part of this package. As a consequence of the method
+% I followed, this bundle contains also the .tfm metric information
+%
+% \section{Usage}
+% The only action needed to use these LX fonts is to call 
+%\begin{verbatim}
+%\usepackage{lxfonts}
+%\end{verbatim}
+% in the preamble; there are no options to set.
+%
+% If you use \pack{beamer} to create your presentation you might need to specify
+%\begin{verbatim}
+%\usefonttheme{professionalfonts}
+%\end{verbatim}
+% in order to avoid that beamer resets some math fonts the way it defaults to;
+% for the rest you don't need to follow a particular loading order, although it
+% might be clearer if you loaded your fonts after specifying the input and 
+% font encoding(s).
+%
+% \section{Standalone usage of the LX fonts}\label{sec:standalone}
+%
+% The style file \texttt{lxfonts.sty} changes all the default font settings
+% so that you cannot use any other font together with the LX ones.
+%
+% You can circumvent this rigidity by using the explicit declaration of the
+% font family you want to use; for example, if you called this package and at a
+% certain point you want to typeset something with a serifed font, say, the
+% T1 encoded Latin Modern roman font, you can define a macro declaration or
+% explicitly specify:
+%\begin{verbatim}
+%{\usefont{T1}{lmr}{m}{n} Words\ldots words}
+%\end{verbatim}
+% By so doing the ``Words\ldots words'' will be typeset in roman medium Latin
+% Modern T1 encoded font at the current size
+%
+% On the opposite if you want to show a sample text written with the LX fonts while
+% you are typesetting with other fonts, you don't use the above .sty file package,
+% but use a macro declaration or the explicit command:
+%\begin{verbatim}
+%{\usefont{T1}{llcmss}{m}{n} Words\ldots words}
+%\end{verbatim}
+% and you get {\usefont{T1}{llcmss}{m}{n} Words\dots words} at the current type
+% size; notice though, how larger the script appears thanks to the larger x-height,
+% but uppercase letters are the same size as the serifed ones.
+%
+% With version 1.0 of this package, this functionality was not possible.
+%
+% \section{Integration of the  Latin and  the Greek scripts}  
+% The Greek CB fonts contain also the  families and shapes for slides;
+% the style is the same as these LX fonts, but the different script does
+% not require any restyling of any glyph; so they can be used directly;
+% but the script changing mechanism simply implies the change of the
+% encoding; therefore in order to  use the above Greek CB fonts, it is
+% simply necessary to have available new font description files whose
+% name is the agglutination of the Greek encoding name  (in lower case)
+% with the family name (identical to that of the Latin script); the contents
+% of such files, of course, retrieves the glyphs from the Greek fonts files.
+%
+% Therefore it should not be difficult in a presentation to specify the Greek
+% language in the preamble of the source file, and use the \pack{babel} language
+% switching commands to as to write something like this:
+% {\usefont{LGR}{llcmss}{m}{n} Kal'' hm'era!} means \emph{Good day!}.                                                                                                                                                                                                                                                                                                                    
+%
+% \section{ The LX fonts demo presentation}
+% This bundle, besides this documentation, is shipped with a demo presentation
+% where most features of the LX fonts are shown; the slides clearly show the
+% features of these fonts, both the positive  and negative ones.  The
+% \emph{legibility}, in my opinion, is excellent; if it was not for this
+% point I would not have undertaken the work of restyling all these fonts.
+% But there ale also some little glitches that are partly inherent to the
+% chosen one-size continuously scalable font. Moreover the Greek fonts,
+% which are not part in themselves of my LX project, requires some
+% adjustments in several kerning values, but at the moment it is acceptable,
+% even if its kerning is not perfect. 
+% 
+% While typesetting math it is clearly noticeable the lack of optical sizes:
+% the super and subscripts appear definitely of the right size, but their
+% scaling makes them appear lighter than they should be; this is common with
+% all fonts that come in one size only, and this happens with the majority
+% of the Type~1 fonts distributed with the \TeX\ system.
+%
+% The Greek font kerning  adjustment is on my TODO list.
+%
+% \section{Acknowledgemts}
+% I would like to thank all the users who appreciated these fonts and
+% gave me some feedback remarking some glitches; in particular I would
+% like to acknowledge the interaction with G\"unter Milde, who gave me
+% precious suggestions, among which that of detaching the font description
+% files form the |lxfonts.sty| file.
+%
+% \StopEventually{}^^A This macro argument can be a bibliography, for example.
+%
+% \section{Documented code}
+% \subsection{The package code}
+% The settings relative to the LX fonts are deferred to the |\AtEndPreamble|
+% hook (defined by package |etoolbox|) so that any previous font setting is
+% replaced by the ones relative to the LX fonts; this is particularly useful
+% when preparing source files for a presentation; in this way all the fonts
+% connected to the the slide show will be homogeneously styled the same way.
+
+% Of course this is not a serious drawback in other situations, since I have
+% shown in section~\ref{sec:standalone} what to do in order to overcome this
+% apparent limitation.
+% 
+% First I test if certain packages have been loaded, specifically packages
+% \pack{latexsym} and \pack{amsfonts}; if so, certain switches are set |true|.
+% At the proper point these switches will be used in order to load or to avoid
+% to load certain font description files that will supersede the ones called
+% by such named packages.
+%
+% At the same time the text and math defaults are set or reset so as to use only
+% the LX fonts.

+% The following tests are needed to load the \AMS\ and the \LaTeX\ symbols
+% fonts; in order to use them it is necessary to input the relevant font
+% description files subject to the switches status; and then it is necessary
+% to redeclare the math fonts accordingly.
+%
+% The |\Join| and |\leadsto| characters had to be redefined or declared

+% the kerning fixed in the |amssymb| package; of course, while I was at it,
+% I might have designed a real glyph for |\Join|, but I thought that it
+% was better to avoid conflicts with the existing \AMS\ symbol definitions.
+% The |\leadsto| character has been let to |\rightsquigarrow| in order
+% to name the same glyph also with the \LaTeX\ symbols font command.
+% In this way it is possible to avoid loading the \LaTeX\ symbols font

+% \subsection{Fonts in T1 encoding}
+% The T1 encoded fonts are now described by the suitable font description
+% files; such fonts are essential for typesetting most languages that use
+% the Latin script. Actually I know that there exist some languages that
+% usually don't use diacritics; but even in such languages sometimes it is
+% necessary to typeset a foreign name or to typeset some phrases or paragraphs
+% in an ancient version of the same language and diacritics pop up again.
+% Personally I believe that T1 encoded fonts should be the only ones to be
+% used, unless the user has access to suitable UNICODE encoded OpenType
+% fonts, but this is out of topic since these LX fonts can be used only
+% by \prog{pdfLaTeX}, that cannot directly handle OpenType fonts.

+%
+% In this case of T1 encoded typewriter fonts I don't use any magnification,
+% as it was done for the OT1 encoded ones, because the upright font exists
+% at the design size of 8pt, but the italic one does not; therefore for
+% homogeneity I thought it was better to use them at a design size of 10pt
+% without any scaling. The differences are so tiny, that are invisible at
+% naked eye.
+% But since the |lcmtt| family is already defined as a standard family, we
+% need a different family name in order to avoid confusion; this is because
+% we use a single size to be enlarged or shrunk as it is done with the main
+% text font.

+% \subsection {The \AMS\ fonts}
+% Since the \AMS\ fonts are used so often, either directly or through
+% the \pack{amssymb} package, I restyled both families |msam| and |msbm|.
+% In the .sty file I kept the math group names the same so that the symbol
+% definitions keep making reference to the same encoding and slot positions,
+% but they take the glyphs from different files.
+%
+% In both cases the |\DeclareFontFamily| statement appears to be unnecessary
+% because these font description files are loaded only if the \pack{amsfonts}
+% package has been called. But we have seen above that these font description
+% files are reloaded at the |\AtEndPreamble| hook; moreover if these fonts are
+% used as standalone ones, the declaration is absolutely necessary.

+% \subsection{The Greek font for slides}
+% The CB Greek font collection contains also the family and shape of the slides
+% fonts; of course with the Greek script there is no problem with possible
+% confusions of capital `I' and lower case `l', therefore they did not need
+% any restyling. The only question related to Greek fonts is that the same
+% font family names for the Latin Script must be associated with the Greek
+% script with the Greek encoding LGR, instead of the Latin encoding T1. The
+% Greek font description files, therefore, have a different prefix (LGR),
+% the same family name (llcmss for proportional sans serif fonts, or lcmtt
+% for monospaced ones), but the glyphs are taken from the relevant Greek fonts.

+% user should not play around with such delicate questions; it must be
+% remarked also that the methods for reconfiguring that file
+% are being updated in a significant way in certain distribution
+% of the \TeX\ system, and it would be very dangerous to describe the
+% 2013 procedure, when it possible that in 2014 it is a different one.
+% In any case the user who really needs to install these fonts ``by hand''
+% is advised to read the documentation of his/her current distribution
+% of the \TeX\ system so as to perform  the update map correct configuration
+% procedure.
