This -% does not mean that we do not agree that there are many -% deficiencies in the design of these classes, but we have many -% tasks with higher priority than continually explaining why the -% standard classes for \LaTeX{} cannot be changed. -% \end{quote} -% -% Back then we probably should have said that this decision also -% covers changes to the \LaTeX{} kernel and font definitions, -% if the change results in -% noticeable differences in the formatting of documents or otherwise -% produces severe incompatibilities between releases. The important -% point to stress here is that ``people rely on the fact that a -% document formatted at one site produces identical output at a -% different site''. By fixing a certain problem in version -% \meta{date}, people making use of the fix will get incorrectly -% formatted documents if they send them to others who still run on a -% version prior to \meta{date}. -% -% In theory one could get around this by adding a line like -% \begin{quote} -% |\NeedsTeXFormat{latex2e}[|\meta{date}|]| -% \end{quote} -% on top of the document. However, this fails for two reasons. Firstly, -% most people will not be aware that they make use of a feature or fix -% that is only available in their version of \LaTeX{}; and thus do not -% add such a line in their documents. Secondly, even if there is such a -% line the receiving site might not be able to upgrade their \LaTeX{} -% in time to process the document properly (the latter is a sad fact -% of life). -% -% By providing the \Lpack{fixltx2e} and \Lpack{fix-cm} packages -% we hope to help people in this respect since, when they -% are used, a document will contain a clear -% indication that special features/fixes are needed and if the -% receiving site does not have the packages available (or not available -% with the right version) it is far easier to download and install them -% from some archive than to upgrade \LaTeX{} in a rush. -% -% The packages are independent from each other and deal with different -% subjects: -% \Lpack{fixltx2e} provides general changes to the \LaTeX{} kernel, -% while \Lpack{fix-cm} improves the definitions of the Computer Modern -% font families. -% -% We will try to maintain the packages in such a way that they can be used -% with all maintenance releases of \LaTeXe{} so that, if urgently -% needed, people can simply add them to the current directory in case -% they cannot upgrade their \LaTeX{} for whatever reason. -% -% The packages are \textbf{NOT} provided so that people can stop -% upgrading their \LaTeX{} system. They will contain only fixes of a -% certain nature, others will still go into the kernel and extensions -% in form of packages, and support files will still be added to the -% base system at regular intervals. -% -% -% \subsection{Using \Lpack{fixltx2e}} -% -% To use the \Lpack{fixltx2e} package include the line -% \begin{quote} -% |\usepackage{fixltx2e}[|\meta{date}|]| -% \end{quote} -% into the preamble of your document, where \meta{date} is the date of -% the \Lpack{fixltx2e} package that you are using. -% This way your document will produce a warning if processed at a site -% that only has an older version of of this package. -% -% \subsection{Using \Lpack{fix-cm}} -% -% \begin{sloppypar} -% To use the \Lpack{fix-cm} package, -% load \danger it \emph{before} \cmd{\documentclass}, -% and use the command \cmd{\RequirePackage} to do so, rather than the -% normal \cmd{\usepackage}: -% \end{sloppypar} -% \begin{verse} -% |\RequirePackage{fix-cm}|\\ -% |\documentclass| \dots -% \end{verse} -% \textbf{Do not to load any other package before the document class}, -% unless you have a thorough understanding of the \LaTeX{} internals -% and know exactly what you are doing! -% -% -% \section{Fixes added} -% -% This section describes all the fixes/features that have been added -% to the initial release of the package.

Documentation and code from this package have been -% merged into this file. -% -% \subsubsection{Notes on the Implementation Strategy} -% -% The standard output routine maintains two lists of floats that have -% been `deferred' for later consideration. One list for single column -% floats, and one for double column floats (which are always -% immediately put onto their deferred list). This mechanism means -% that \LaTeX\ `knows' which type of float is contained in each box -% by the list that it is processing, but having two lists means -% that there is no mechanism for preserving the order between the -% floats in each list. -% -% The solution to this problem consists of two small changes to -% the output routine. -% -% Firstly, abandon the `double column float list' |\@dbldeferlist| -% and change every command where it is used so that instead the -% same |\@deferlist| is used as for single column floats. -% That one change ensures that double and single column floats -% stay in the same sequence, but as \LaTeX\ no longer `knows' -% whether a float is double or single column, it will happily -% insert a double float into a single column, overprinting the -% other column, or the margin. -% -% The second change is to provide an alternative mechanism for -% recording the two column floats. \LaTeX\ already has a compact -% mechanism for recording float information, an integer count register -% assigned to each float records information about the `type' of float -% `figure', `table' and the position information `htp' etc. -% -% The type information is stored in the `high' bits, one bit position -% (above `32') allocated to each float type. The `low' bits store -% information about the allowed positions, one bit each allocated for -% |h t b p|. In the \LaTeX2.09 system, the bit corresponding to `16' -% formed a `boundary' between these two sets of information, and it -% was never actually used by the system. Ed Sznyter's -% \package{fixfloats} package not unreasonably used this position to -% store the double column information, setting the bit for double -% column floats. Then at each point in the output routine at which a -% float is committed to a certain region, an additional check must be -% made to check that the float is (or is not) double column. If it -% spans the wrong number of columns it is deferred rather than being -% added. -% -% Unfortunately the bit `16' is not available in \LaTeXe. It is used -% to encode the extra float position possibility `|!|' that was added -% in that system. It would be possible to use position `32' and to -% move the flags for `table', `figure',\ldots\ up one position, to -% start at 64, but this would mean that in principle one less float -% type would be supported, and more importantly is likely to break -% any other packages that assume anything about the output routine -% internals. So here I instead use another mechanism for flagging -% double column floats: By default all floats have depth 0pt. -% This package arranges that double column ones have depth 1sp. -% This information may then be used in the same manner as in -% the \package{fixfloats} package, to defer any floats that are not of -% the correct column spanning type. -% -% -% -% \subsection{Wrong header for twocolumn (pr/2613)} -% -%\begin{verbatim} -% >Number: 2613 -% >Category: latex -% >Synopsis: wrong headline for twocolumn -% >Arrival-Date: Mon Sep 22 16:41:09 1997 -% >Originator: daniel@cs.uni-bonn.de (Daniel Reischert) -% >Description: -% When setting the document in two columns -% the headline shows the top mark of the second column, -% but it should show the top mark of the first column. -% \end{verbatim} -% -% Originally fixed in package \Lpack{fix2col} which was merged into -% this package. Documentation and code from this package have been -% merged into this file. -% -% \subsubsection{Notes on the Implementation Strategy} -% -% The standard \LaTeX\ twocolumn system works internally by making -% each column a separate `page' that is passed independently to \TeX's -% pagebreaker. (Unlike say the \package{multicol} package, where all -% columns are gathered together and then split into columns later, -% using |\vsplit|.) This means that the primitive \TeX\ marks that are -% normally used for header information, are globally reset after the -% first column. By default \LaTeX\ does nothing about this. -% A good solution is provided by Piet van Oostrum (building on earlier -% work of Joe Pallas) in his \package{fixmarks} package. -% -% After the first column box has been collected the mark information -% for that box is saved, so that any |\firstmark| can be -% `artificially' used to set the page-level marks after the second -% column has been collected. (The second column |\firstmark| is not -% normally required.) Unfortunately \TeX\ does not provide a direct -% way of knowing if any marks are in the page, |\firstmark| always has a -% value from previous pages, even if there is no mark in this page. -% The solution is to make a copy of the box and then |\vsplit| it -% so that any marks show up as |\splitfirstmark|. -% -% The use of |\vsplit| does mean that the output routine will globally -% change the value of |\splitfirstmark| and -% |\splitbotmark|. The \package{fixmarks} package goes to some trouble -% to save and restore these values so that the output routine does -% \emph{not} change the values. This part of \package{fixmarks} is not -% copied here as it is quite costly (having to be run on every page) and -% there is no reason why anyone writing code using |\vsplit| should -% allow the output routine to be triggered before the split marks have -% been accessed. -% -% -% \subsection{\texttt{\textbackslash @} discards spaces when moving -% (pr/3039)} -% -%\begin{verbatim} -% >Number: 3039 -% >Category: latex -% >Synopsis: \@ discards spaces when moving -% >Arrival-Date: Sat May 22 09:01:06 1999 -% >Originator: asnd@triumf.ca (Donald Arseneau) -% >Description: -% The \@ command expands to \spacefactor\@m in auxiliary files, -% which then ignores following spaces when it is reprocessed. -%\end{verbatim} -% -% \subsection{\texttt{\textbackslash setlength} produces error if -% used with registers like \texttt{\textbackslash dimen0} (pr/3066)} -% -%\begin{verbatim} -% >Number: 3066 -% >Category: latex -% >Synopsis: \setlength{\dimen0}{10pt} -% >Arrival-Date: Tue Jul 6 15:01:06 1999 -% >Originator: oberdiek@ruf.uni-freiburg.de (Heiko Oberdiek) -% >Description: -% The current implementation of \setlength causes an error, -% because the length specification isn't terminated properly. -% More safe: -% \def\setlength#1#2{#1=#2\relax} -%\end{verbatim} -% -% \subsection{\texttt{\textbackslash addpenalty} ruins flush-bottom (pr/3073)} -% -%\begin{verbatim} -% >Number: 3073 -% >Category: latex -% >Synopsis: \addpenalty ruins flush-bottom -% >Arrival-Date: Sat Jul 17 05:11:05 1999 -% >Originator: asnd@triumf.ca (Donald Arseneau) -% >Description: -% Just to keep in mind for further development eh? -% A page break at an \addpenalty after \vspace does *not* -% give a flush-bottom page.

In a nutshell, if one adds -%\begin{verbatim} -%\usepackage[T1]{fontenc} -%\end{verbatim} -% to a document that uses the Computer Modern typefaces, -% then not only the T1 encoding is used but the fonts -% used in the document look noticeably different. This is due to the fact -% that the EC fonts have more font series designs, e.g.\ a 14.4\,pt bold -% etc and those get used in the standard \texttt{.fd} files, while -% with Computer Modern (in OT1 encoding) such sizes were scaled -% versions of smaller sizes---with a noticeable different look and -% feel. -% -% So we provide a package \Lpack{fix-cm} to ensure that comparable -% definitions are used. In addition to that, the package -% \Lpack{fix-cm} also enables continuous scaling of the CM fonts. -% This package was written by Walter Schmidt. -% -% -% -%^^A \section{The macro package \textsf{fix-cm} for \LaTeXe} -% -%^^A The documentation in this section was prepared by Walter Schmidt. -% -% -% -% \subsubsection{What \Lpack{fix-cm} does} -% -% ^^A Are you bothered by the T1 and TS1 encoded Computer Modern fonts, -% ^^A which look partially worse than the traditional ones? Would you -% ^^A like to use the CM fonts with arbitrary sizes? If so, the macro -% ^^A package \Lpack{fix-cm} can help you. -% -% Loading the package \Lpack{fix-cm} changes the font definitions of the -% Computer Modern fonts, in order to achieve the following effects: -% \begin{itemize} -% \item -% The appearance of the T1 and TS1 encoded CM fonts (aka `EC') is -% made as similar as possible to the traditional (OT1 encoded) ones. -% Particularly, a number of broken or ugly design sizes are no -% longer used, the look of the bold sans serif typeface at large -% sizes is considerably improved, and mismatches between the text -% fonts and the corresponding math fonts are avoided. As a side -% effect, PostScript and PDF documents may become smaller, because -% fewer fonts need to be embedded. -% \item -% The Computer Modern fonts are made available with arbitrary sizes. -% \item -% Only those design sizes of the fonts will be used, that are -% normally available in Type1 format, too. You need not load the -% extra package \Lpack{cmmib57} for this purpose. -% \end{itemize} -% The package acts on the following font families: -% \begin{itemize} -% \item -% The text font families \file{cmr}, \file{cmss}, \file{cmtt} and -% \file{cmvtt} with OT1, T1 and TS1 encoding. -% \item -% The default math fonts used by \LaTeX, i.e., the font families -% \file{cmm} with encoding OML and \file{cms} with encoding OMS. -% \item -% The symbols used by the package \Lpack{latexsym}, i.e., the font -% family \file{lasy}. -% \end{itemize} -% Note that the package does \emph{not} act on: -% \begin{itemize} -% \item Font families such as CM~Fibonacci, CM~Dunhill etc., -% which are provided for experimental purposes or for fun only. -% \item -% CM text fonts with character sets other than Latin, e.g., -% Cyrillic. Loading of the required font and encoding definitions -% while the fonts are not actually used, would not be a good idea. -% This should be addressed by particular packages or by changing the -% standard FDs of these fonts. -% \item -% Extra math fonts such as the AMS symbol fonts. While -% they match the style of Computer Modern, they are frequently used -% in conjunction with other font families, too. Thus, -% \Lpack{fix-cm} is obviously not the right place to make sure that -% they can be scaled continuously. Ask the maintainers of these -% fonts to provide this feature, which is badly needed! -% \item -% The math extension font \file{cmex}. Whether or not this font -% should be scaled is a question of its own, and there are other -% packages (\Lpack{exscale}, \Lpack{amsmath}, \Lpack{amsfonts}) to -% take care of it. -% \end{itemize} -% -% \subsubsection{How to load the package} -% \begin{sloppypar} -% The package should be loaded \danger \emph{before} \cmd{\documentclass}, -% using the command |\RequirePackage{fix-cm}|, rather than the -% normal \cmd{\usepackage}. -% Rationale: -% If the package is loaded in the preamble, a preceding package or -% even the code of the document class may have used any of the CM -% fonts already. However, the definitions of those fonts, that are -% already in use, cannot be changed any more. -% \end{sloppypar} -% -% \subsubsection{Usage notes} -% In contrast to what you may expect, \Lpack{fix-cm} does \emph{not} -% ensure that line and page breaks stay the same, when you switch an -% existing document from OT1 to T1 encoding. The package does not -% turn off all of the additional design sizes in the EC fonts -% collection: Those, that contribute considerably to the typographical -% quality and do not conflict with the math fonts, -% are---indeed---used. -% -% Be careful when using arbitrary, non-standard font sizes with -% applications that need bitmap fonts: You may end up \danger with -% lots of possibly huge \file{.pk} files. Also, \MF{} chokes -% sometimes on extremely small or large sizes, because of arithmetic -% problems. -% -% \Lpack{fix-cm} supersedes the experimental packages \Lpack{cmsd} and -% \Lpack{fix-ec}, which are no longer distributed. -% -% The packages \Lpack{type1cm} and \Lpack{type1ec} must not be loaded -% additionally; they enable only continuous scaling. -% -% -% -% \section{Fixes added for 2005/12/01} -% -% \subsection{\texttt{\textbackslash textsubscript} not defined in -% latex.ltx (pr/3492)} -% -%\begin{verbatim} -% >Number: 3492 -% >Category: latex -% >Synopsis: \textsubscript not defined in latex.ltx -% >Arrival-Date: Tue Jan 14 23:01:00 CET 2003 -% >Originator: tgakic@chem.tue.nl (Ionel Mugurel Ciobica) -% -% I use \textsubscript much more often than \textsuperscript, and -% \textsubscript it is not defined in latex.ltx.
