% \GetFileInfo works. However, I need to manually set the current file name
% and extension that would normally be set by \RequirePackage. Also, note that
% the call to \GetFileInfo below needs to use the extension of the header,
% that is inc instead of sty, even the file fixme.inc does not really exist.

%
% \begin{abstract}
%   \fx is a collaborative annotation tool for \LaTeX{} documents. Annotating
%   a document here refers to inserting meta-notes, that is, notes that do not
%   belong to the document itself, but rather to its development or reviewing
%   process. Such notes may involve things of different importance levels,
%   ranging from simple ``fix the spelling'' flags to critical ``this
%   paragraph is a lie'' mentions. Annotations like this should be visible
%   during the development or reviewing phase, but should normally disapear in
%   the final version of the document.
%
%   \fx is designed to ease and automate the process of managing collaborative
%   annotations, by offering a set of predefined note levels and layouts, the
%   possibility to register multiple note authors, to reference annotations by
%   listing and indexing \etc \fx is extensible, giving you the possibility to
%   create new layouts or even complete ``themes'', and also comes with
%   support for \auctex.
%
%   The \fx package is \packagecopyright{}, and distributed under the
%   terms of the LPPL license.

%
% \section{Installation}
% \subsection{Extraction}
% If you are building \fx from the tarball you need to execute the following
% steps in order to extract the necessary files. \fx also requires the
% \textsf{DoX} package (version 2.0, release date 2009/09/21 or later), to
% build. It is not required to use the package.
% \begin{verbatim}
% [pdf]latex fixme.ins
% [pdf]latex fixme.dtx
% [pdf]latex fixme.dtx
% makeindex -s gind fixme.idx
% [pdf]latex fixme.dtx
% [pdf]latex fixme.dtx
% \end{verbatim}
% After that, you need to install the generated documentation and style files
% to a location where \LaTeX{} can find them.
%
% \subsection{TDS-compliant layout}
% For a TDS-compliant layout, the following locations are suggested:
% \begin{verbatim}
% [TEXMF]/tex/latex/fixme/fixme.sty
% [TEXMF]/tex/latex/fixme/layouts/fxlayout*.sty
% [TEXMF]/tex/latex/fixme/layouts/env/fxenvlayout*.sty
% [TEXMF]/tex/latex/fixme/layouts/target/fxtargetlayout*.sty
% [TEXMF]/tex/latex/fixme/themes/fxtheme*.sty
% [TEXMF]/doc/latex/fixme/fixme.[pdf|dvi]
% \end{verbatim}
%
% \subsection{\auctex support}
% \auctex is a powerful major mode for editing \TeX{} documents in
% \emacs. In particular, it provides automatic completion of command names
% once they are known. \fx supports \auctex by providing a style file named
% \texttt{fixme.el} which contains \auctex definitions for the relevant
% commands. This file should be installed in a place where \auctex can find it
% (usually in a subdirectory of your \LaTeX{} styles directory). Please refer
% to the \auctex documentation for more information on this.
%
% \section{Features summary}
% If you're new to \fx, you might be interested in a brief summary of the
% features it provides. Otherwise, you may only take a look at the History
% section (section \sectionref{sec:manual:history}) to see what's new.
% \subparagraph{Annotation levels} \fx annotations may be of four different
% importance levels, ranging from simple not-so-important notices to critical
% things that must absolutely be fixed in the final version.
% \subparagraph{Layouts and themes} \fx gives you full and extensible control
% on the layout of these annotations: they can be displayed inline, as
% marginal paragraphs, as footnotes and also in any kind of user-defined way.
% All these ``layouts'' may be combined together. \fx also comes with support
% for ``themes'', globally modifying existing layouts, or providing new ones.
% \subparagraph{Annotation targets} Annotations may be ``targeted'' to a
% specific portion of text that will be highlighted, and on the contrary
% ``floating'' around, in which case they may even appear in the document's
% preamble.
% \subparagraph{Listing and indexing} Annotations may be indexed and
% summarized in a ``list of fixmes''.
% \subparagraph{Logging} Annotations are recorded in the log file, and
% (depending on their importance level) some of them are displayed on the
% terminal during compilation. A final summary is also created at the end of
% the compilation process.
% \subparagraph{Modes} All these features are actually available when you're
% working in \texttt{draft} mode. In \texttt{final} mode, the behavior is
% slightly different: any remaining critical note generates an error (the
% compilation aborts), while non critical ones are just removed from the
% document's body (they're still recorded in the log file though).
% \subparagraph{Authoring} \fx provides support for collaborative annotating
% by allowing you to ``register'' several authors.
% \subparagraph{Internationalization} \fx currently supports 7 different
% languages and features automatic language tracking for multilingual
% documents.
%
% \section{Using \fx}
% \subsection{Initialization}
% \subsubsection{Requirements}
% In order to work properly, \fx requires the presence of some \LaTeX{}
% packages. You don't have to load them explicitly though. As long as
% \LaTeX{} can locate them, they will be used automatically. \fx currently
% depends on \texttt{xspace}, \texttt{ifthen}, \texttt{verbatim} and
% \texttt{xkeyval} (version 2.5f, release date 2006/11/18 or later).
%
% \subsubsection{Loading the package}
% In order to load \fx, simply say |\usepackage[|\meta{options}|]{fixme}|
% in the preamble of your document. There is an important number of options
% that you can use in order to customize \fx's default or global behavior.
% These options will be discussed when appropriate.
%
% There might be times where you would like to use \LaTeX{} commands in
% package options (for example, see section \sectionref{sec:manual:faces}). In
% such a case, you should know that \LaTeX{} normally can't handle this. In
% order to make it work, you need to use the \texttt{xkvltxp} package first,
% like this:
% \begin{verbatim}
% \usepackage{xkvltxp}
% \usepackage[myoption=\mymacro]{fixme}
% \end{verbatim}
%
% \subsubsection{Global setup modification}
% \DescribeMacro{\fxsetup}\marg{options}\\
% Another way of customizing \fx's global behavior is to use the
% \cs{fxsetup} command. \cs{fxsetup} understands the same options as the
% package itself and can be used in the preamble as well as in the document's
% body.
%
% \subsubsection{Local setup modification}
% Finally, note that unless specified otherwise, all package options are also
% understood by the annotation commands or environments described in
% section \sectionref{sec:manual:insertion}. The effect is then local to that
% particular command.
%
% \subsection{Inserting \fx notes\label{sec:manual:insertion}}
% \subsubsection{Commands}
% \DescribeMacro{\fxnote}
% \DescribeMacro{\fxwarning}
% \DescribeMacro{\fxerror}
% \DescribeMacro{\fxfatal}\oarg{options}\marg{note}\\
% \fx provides four annotation commands corresponding to different
% levels of importance (notes, warnings, errors and fatal errors).
% \cs{fxfatal} is a bit different from the other ones, as will be explained in
% section \sectionref{sec:manual:behavior}.\par
% \begin{quotation}\itshape
%   \DescribeMacro{\fixme}
%   \textbf{Warning:} as of version 4, the \cs{fixme} command is a synonym for
%   \cs{fxfatal} and is considered deprecated.
% \end{quotation}
%
% \subsubsection{Targeted commands}
% \DescribeMacro{\fxnote*}
% \DescribeMacro{\fxwarning*}
% \DescribeMacro{\fxerror*}
% \DescribeMacro{\fxfatal*}\oarg{options}\marg{note}\marg{text}\\
% Sometimes, you might not only want to issue a \fx note, but also
% highlight the relevant part of the text to which it applies. This is what I
% call ``targeting'' the note. As of version 4, \fx provides starred
% versions of its annotation commands to do that. In star form, these
% commands expect an additional mandatory argument containing the text to be
% highlighted.
%
% \subsubsection{Environments}
% \begin{quotation}\itshape
%   \textbf{Warning:} as of version 4.0, the environment interface has changed
%   and is \emph{not} backward-compatible.
% \end{quotation}
% \DescribeEnv{anfxnote}
% \DescribeEnv{anfxwarning}
% \DescribeEnv{anfxerror}
% \DescribeEnv{anfxfatal}\oarg{options}\marg{summary}\\
% \fx annotations are normally meant to be short: consider that they are
% likely to go in the list of fixmes and in the index for instance. If you
% feel the need for writing longer comments, the environments described below
% might come in handy. \fx provides four annotation environments; one for
% every note level. These environments take one mandatory argument (meant to
% be a short summary of the long note) and behave in exactly the same way as
% their command counterpart. The layout policy is a bit different though (see
% section
% \sectionref{sec:manual:layout}): the environment's contents will always
% appear inline, and the \meta{summary} will obey all active annotation
% layouts except for the \texttt{inline} one, just as if it had been passed to
% one of the \fx annotation commands described in the previous section.
% \begin{quotation}\itshape
%   \DescribeEnv{afixme}
%   \textbf{Warning:} as of version 4, the \texttt{afixme} environement is a
%   synonym for \texttt{anfxfatal}, and is considered deprecated.
% \end{quotation}
%
%
%
% \subsubsection{Targeted environments}
% \DescribeEnv{anfxnote*}
% \DescribeEnv{anfxwarning*}
% \DescribeEnv{anfxerror*}
% \DescribeEnv{anfxfatal*}\oarg{options}\marg{summary}\marg{text}\\
% \fx environments can also be targeted to a specific portion of text. When
% using the starred version, the environments expect one additional mandatory
% argument: the text in question that will be highlighted.
%
% \subsection{List of \fx's\label{sec:manual:lox}}
% \DescribeMacro{\listoffixmes}
% \fx remembers where you put your annotations in a toc-like file whose
% extension is \texttt{lox}. The \cs{listoffixmes} command generates the
% annotations lists in a manner similar to that of the ``list of figures''. A
% standard layout is automatically selected for the \texttt{article},
% \texttt{report}, \texttt{book} classes and their \komascript replacements.
% If another class is used, the \texttt{article} layout is selected. Also,
% note that if there isn't any annotation left in the document, this command
% doesn't generate an empty list, but rather stays silent. It also stays
% silent in \texttt{final} mode, regardless of the presence of remaining
% annotations (see section \sectionref{sec:manual:behavior}).
%
% \subsection{Controlling the behavior of \fx\label{sec:manual:behavior}}
% \DescribeOption{final}
% \DescribeOption{draft}
% The behavior of \fx is controlled by the two standard options
% \texttt{final} and \texttt{draft}. These options are usually given to
% \cs{documentclass} which in turn passes them to all packages. In addition,
% you can also use them as options to \cs{usepackage}, in the call to
% \cs{fxsetup}, and even to the annotation commands and environments.
%
% In \texttt{draft} mode, annotations are recorded in the log file and appear
% in the document as specified by the layout settings (see section
% \sectionref{sec:manual:layout}). Additionally, warnings, errors and fatal
% errors are also displayed on the terminal.
%
% In final mode, non fatal annotations (those generated by \cs{fxnote},
% \cs{fxwarning}, \cs{fxerror} and their corresponding environments) are still
% logged, but they're not typeset. On the other hand, fatal ones (those
% generated by the \cs{fxfatal} command and the \texttt{anfxfatal}
% environment) will throw a \LaTeX{} error and thus interrupt or abort
% compilation with an informative message. This will help you track down
% forgotten important caveats in your document.
%
% Let me rephrase: final documents can only have \fx notes, warnings, and (non
% fatal) errors left. Of course, this is not completely true: remember that
% these options are understood locally by all the annotation commands and
% environments, so even in \texttt{final} mode, you can use something like
% this:
% \begin{verbatim}
% \fxfatal[draft]{bla bla}
% \end{verbatim}
%
% \DescribeOption{status}
% By default, \fx is in \texttt{final} mode (\LaTeX{} itself behaves that
% way). If you're manipulating the document status at the level of \fx
% itself (as opposed to the \cs{documentclass} level), then the preferred way
% to do this is to use the \texttt{status} option, and give it the value
% \texttt{final} or \texttt{draft}.
%
% \subsection{Controlling the layout of annotations\label{sec:manual:layout}}
% Annotations can appear in several forms in your document. Each of these
% forms can be individually selected, or they can be combined together to some
% extend.
%
% \subsubsection{Selecting a layout}
% \paragraph{Individual control}
% For each annotation layout, there is a corresponding boolean option (for
% instance, the ``inline'' layout is controlled by the \texttt{inline}
% option). These options are understood by the package itself, the
% \cs{fxsetup} command and also locally by every annotation command or
% environment. There are some restrictions on their usage however, as
% discussed in the next section.
%
% To activate a note layout, use the option alone or give it a value of
% \texttt{true}. For instance, these two forms are equivalent:
% \begin{verbatim}
% \fxnote[inline]{note...}
% \fxnote[inline=true]{note...}
% \end{verbatim}
% For convenience, each layout option has a counterpart that deactivates the
% corresponding layout. The counterpart option has the same name, prefixed
% with \texttt{no} (for instance, \texttt{noinline}). Again, these options are
% understood by the package itself, the \cs{fxsetup} command and also locally
% by every annotation command or environment (with the same usage
% restrictions, discussed in the next section). For instance, these two forms
% are equivalent:
% \begin{verbatim}
% \fxsetup{inline=false}
% \fxsetup{noinline}
% \end{verbatim}
%
% \paragraph{Global control}
% \DescribeOption{layout}
% \DescribeOption{morelayout}
% An even more convenient way to specify the required layout is to use the
% \texttt{layout} and \texttt{morelayout} options. In fact, the use of
% individual control is considered more or less deprecated. Both of these
% options take a comma-separated list of the individual options described
% above (this includes the \texttt{no}\meta{option} form as well).
%
% While the \texttt{morelayout} option \emph{adds} to the current layout
% configuration, the \texttt{layout} one completely overrides it. For
% instance, knowing that by default, only the \texttt{margin} layout is
% active, the following forms are all equivalent:
% \begin{verbatim}
% \usepackage[nomargin,inline,index]{fixme}
% \usepackage[margin=false,inline=true,index=true]{fixme}
% \usepackage[morelayout={nomargin,inline,index}]{fixme}
% \usepackage[layout={inline,index}]{fixme}
% \end{verbatim}
% Again, these two options are understood by the package itself, the
% \cs{fxsetup} command and also locally by every annotation command or
% environment (with the same usage restrictions, discussed in the next
% section).
%
% \noindent\DescribeMacro{\fxuselayouts}\marg{name,\ldots}\\
% Finally, an alternative way of selecting (or deselecting) several layouts
% simultaneously is to use the \cs{fxuselayouts} command, giving it a
% comma-separated list of layout options as its only, mandatory, argument.
%
% \subsubsection{Built-in \vs external layouts}
% Annotation layouts are provided either in the core of \fx, or in separate
% files loaded dynamically on demand. Simple layouts are typically built-in,
% whereas those requiring additional packages are external, so that they don't
% consume \TeX{} resources if not used. As a consequence, selecting an
% external layout might involve loading the relevant file first.
%
% \noindent\DescribeMacro{\fxloadlayouts}\marg{name,\ldots}\\
% For technical reasons, it is not possible to do such a thing outside the
% preamble, neither in the middle of processing \cs{usepackage} options. As a
% result, layout options are restricted and you have three possibilities for
% using an external layout:
% \begin{enumerate}
% \item Use its corresponding option in a call to \cs{fxsetup} in the
%   preamble, like this: |\fxsetup{|\meta{option}|}|. This will load it
%   \emph{and} select it immediately.
% \item Use the \cs{fxuselayouts} command in the preamble like this:\\
%   |\fxuselayouts{|\meta{name}|}|. This is strictly equivalent to the
%   previous solution.
% \item If on the other hand you want to load one or several external layouts
%   \emph{without} using them immediately (perhaps in order to use them
%   locally in some specific annotation), use the \cs{fxloadlayouts} command
%   in the preamble like this: |\fxloadlayouts{|\meta{name}|,...}|. After
%   that, you can select any of those layouts anywhere you wish.
% \end{enumerate}
%
% \subsubsection{Available layouts}
% \DescribeBooleanOption{inline}
% \DescribeBooleanOption{margin}
% \DescribeBooleanOption{footnote}
% \DescribeBooleanOption{index}
% \DescribeLayout[noprint]{inline}
% \DescribeLayout[noprint]{margin}

% \DescribeLayout[noprint]{index}
% Table \ref{table:layouts} lists the annotation layouts currently distributed

% these layouts should be self-explanatory, but some precisions are given

% \end{table}
% \paragraph{\texttt{marginclue}}
% \DescribeBooleanOption{marginclue}
% \DescribeLayout[noprint]{marginclue}
% If your preferred layout is \texttt{inline} or say, \texttt{footnote},it
% might be somewhat difficult to localize the annotation on the page,
% especially its vertical position. That's where marginal clues come into
% play. A marginal clue does not display the annotation's contents, but only
% an indication that there is one at that (vertical) position. So you need to
% use another layout as well (again, typically \texttt{inline} or
% \texttt{footnote}) in order to get the actual annotation.
%
% Obviously, the margin and margin clue layouts are mutually exclusive, so if
% you try to activate both, only the most recently activated one will be
% enabled (and you'll get a notice in the log file and on the terminal).
%
% \paragraph{\texttt{marginnote}}
% \DescribeBooleanOption{marginnote}
% \DescribeLayout[noprint]{marginnote}
% The \texttt{marginnote} layout is an alternate (external) way to display
% annotations in the margin, using the eponymous package. Contrary to \LaTeX's
% standard marginal paragraphs, the ones issued by \texttt{marginnote} are
% constructed in a non-floating way. This might be an advantage in some
% situations but \texttt{marginnote} also comes with some disadvantages of its
% own. For more information, please refer to \texttt{marginnote}'s
% documentation, and also read the next section. Also, note that it is not
% currently possible to pass options to the \cs{marginnote} command through
% this layout.

% The PDF format comes with a concept of \emph{comment}, which \fx can use to
% display its own annotations. Support for PDF comments varies across PDF
% viewers. Acrobat Reader is usually considered a reference, and MacOS X's
% Preview supports them reasonably well. The \texttt{pdfnote} and
% \texttt{pdfmargin} layouts use the \texttt{pdfcomment} package to display
% annotations as PDF inline or marginal comments.
%
% The \texttt{sig} versions additionally display the author's tag (see
% \sectionref{sec:manual:modes}) as a signature instead of as a prefix.
%
% The versions with a \texttt{c} in their name (as in \textbf{c}olor) use one
% of four different colors named \texttt{fx}\meta{level} (according to the
% annotation's importance level). They also avoid printing the annotation's
% level since this information is already conveyed by the color.
%
% \subsubsection{Inner layout}
% There might be various reasons for you to change the layout locally for one
% particular annotation: creating a floating one is an example, see also
% section \sectionref{sec:manual:othercommonproblems} for some others. One
% frequent reason (described below) can be handled automatically by \fx.
%
% Remember that the default layout is to use margin paragraphs. Unfortunately,
% margin paragraphs are forbidden by \TeX{} in several situations, like a
% figure's caption for instance. If you try that, you will get a cryptic ``Not
% in outer par mode'' error message.
%
% \DescribeOption{innerlayout}
% The good news is that this situation can be detected automatically. \fx
% provides an option named \texttt{innerlayout} that allows you to specify an
% alternative layout setting to use when \TeX{} is in \emph{inner} mode. In
% addition to that, \fx automatically disables the \texttt{margin} and
% \texttt{marginclue} layouts. If you really want to use marginal paragraphs
% in inner mode, a good idea is then to set your inner layout to
% \texttt{marginnote} (see the previous section).
%
% Using \texttt{innerlayout} is not as trivial as it may seem: it
% \emph{really} is an alternative layout configuration, and as such, you can
% use any combination you like of individual layout options, or you can even
% use the \texttt{layout} and \texttt{morelayout} options. This means that
% your alternative layout can either \emph{add} to the existing one, or
% \emph{override} it. Here are some examples to clarify things a little. You
% should try to understand them.
% \begin{itemize}
% \item By default, the \fx inner layout is set to just \texttt{inline}.
%   This can be simulated by the following call:
% \begin{verbatim}
% \usepackage[layout=margin,innerlayout={layout=inline}]{fixme}
% \end{verbatim}
% \item The following happens to give the same result in our particular case,
%   while having a different semantics:
% \begin{verbatim}
% \usepackage[layout=margin,innerlayout=inline]{fixme}
% \end{verbatim}
% \item If you have set \fx to use a safe layout globally (for instance,
%   \texttt{inline} and \texttt{index}), and you want to use the same layout
%   in inner mode, then you should provide an \emph{empty} inner layout, like
%   this:
% \begin{verbatim}
% \fxsetup{layout={inline,index},innerlayout=}
% \end{verbatim}
%   What would happen if you didn't provide the \texttt{innerlayout} option?
% \end{itemize}
%
% One final remark on the \texttt{innerlayout} option: this option is not
% processed immediately when you specify it, but instead, its value is stored
% and used only when needed. As a result, if you plan to use an external
% layout in inner mode (typically, \texttt{marginnote})~, you need to load it
% explicitely in the preamble first. Use \cs{fxloadlayouts} for that.
%
% \subsubsection{Other common layout
%   problems\label{sec:manual:othercommonproblems}}
% This section describes some other common problems that people have
% encountered using \fx. Although \fx might not be directly responsible
% for them, it is still good to keep them in mind.
%
% \subparagraph{Footnotes and margin paragraphs in floats} Using footnotes in
% figures (and \emph{a fortiori} in a figure's caption) does not work in
% general. Although there are some workarounds out there (for instance, using
% \cs{footnotemark} and \cs{footnotetext} directly), there is no completely
% reliable solution and it is not possible to detect that situation
% automatically. Similarly, marginal paragraphs will cause problems in a
% figure (even when not in its caption) because floats can't be nested in
% \LaTeX. Usual symptoms of these situations are: a footnote not being
% typeset, compilation breakage with the ``Floats lost'' message \etc If
% you're facing this problem, you need to change your layout locally.
%
% \subparagraph{Marginal paragraphs showing up on the wrong margin} You want
% to look at the \texttt{mparhack} package.
%
% \subparagraph{ACM classes compatibility} The ACM \textsc{Sig} classes
% (\texttt{acm\_proc\_article-sp} and \texttt{sig-alternate}) forbid the use
% of \cs{marginpar}, so if you use these classes, don't forget to choose
% another layout for \fx, and also avoid using marginal clues.
%
% \subparagraph{Annotation indexing}
% Remember that some characters are special in an index entry (the \texttt{!}
% for instance). \fx currently does nothing to escape those characters, so
% avoid using them in your annotations.
%
% \subsection{Corollary: floating annotations}
% At some point, people suggested that it would be nice to have global
% annotations, not related to any portion of the text in particular. Such
% annotations could be general comments about the whole document, and could
% even be issued in the preamble. This is what I call ``floating''
% annotations.
%
% I know you don't care, but originally, I started writing a new set of
% commands to do just that. However, with the flexibility that \fx 4.0
% provides, I quickly realized that such commands were an unnecessary
% addition.
%
% Since floating anotations are not supposed to relate to any part of the
% text, they should not be typeset anywhere in it. This is especially true if
% you want to put some of them in the document's preamble. However, even a
% preamble annotation could be recorded and displayed in the index or in the
% list of fixmes. And it turns out that you can specify all that with the
% layout options described in section \sectionref{sec:manual:layout}.
%
% \DescribeOption{target}
% The only remaining problem is the page number, which normally appears in the
% list of fixmes and in the index: if you choose to reference a floating
% annotation that way, the page number is likely to be completely meaningless.
% To compensate, a new option named \texttt{target} is provided. When used,
% the given value will replace the page number in both the index and the list
% of fixmes. The target can be anything you like, but should remain rather
% short. By default, \texttt{target} is set the special value
% \texttt{thepage}, which as you guessed means to use the page number.
%
% The name "target" bears an intentional resemblance to \fx's targeted
% commands and environments, because we are indeed targetting the note to
% something. The only difference is that in the case of floating annotations,
% the target is non-textual.
%
% Here is an example of a floating annotation that would typically appear in
% the document's preamble:
% \begin{verbatim}
% \usepackage{hyperref}
% \fxfatal[layout=index,target=hyperref]{Fill in PDF fields (title etc.)}
% \end{verbatim}
%
% \subsection{Controlling the layout of
%   environments\label{sec:manual:envlayoutcontrol}}
% As discussed in section \sectionref{sec:manual:insertion}, the contents of a
% \fx environment (a longer annotation) always appears inline. However, the
% exact way this contents is typeset (in draft mode only) is subject to a
% layout of its own, called the ``environment layout''.
%
% \subsubsection{Selecting a layout}
% \DescribeOption{envlayout}
% The desired environment layout can be selected with the \texttt{envlayout}
% option. Contrary to the annotation layouts, only one environment layout can
% be active at a time. The \texttt{envlayout} option is understood by the
% package itself, the \cs{fxsetup} command and all the annotation environments
% (not the commands!). There are some restrictions on its usage however, as
% discussed in the next section.
%
% \noindent\DescribeMacro{\fxuseenvlayout}\marg{name}\\
% An alternative way of selecting an environment layout is to use the
% \cs{fxuseenvlayout} command, giving it the layout's name as its only,
% mandatory, argument.
%
% \subsubsection{Built-in \vs external layouts}
% Environments layouts are provided either in the core of \fx, or in separate
% files loaded dynamically on demand. Simple layouts are typically built-in,
% whereas those requiring additional packages are external, so that they don't
% consume \TeX{} resources if not used. As a consequence, selecting an
% external layout with the \texttt{envlayout} option might involve loading the
% relevant file first.
%
% \noindent\DescribeMacro{\fxloadenvlayouts}\marg{name,\ldots}\\
% For technical reasons, it is not possible to do such a thing outside the
% preamble, neither in the middle of processing \cs{usepackage} options. As a
% result, the \texttt{envlayout} option is restricted and you have three
% possibilities for using an external layout:
% \begin{enumerate}
% \item Use the \texttt{envlayout} option in a call to \cs{fxsetup} in the
%   preamble, like this: |\fxsetup{envlayout=name}|. This will load it
%   \emph{and} select it immediately.
% \item Use the \cs{fxuseenvlayout} command in the preamble like this:\\
%   |\fxuseenvlayout{name}|. This is strictly equivalent to the previous
%   solution.
% \item If on the other hand you want to load one or several environment
%   layouts \emph{without} using them immediately (perhaps in order to use
%   them locally in some specific annotation), use the \cs{fxloadenvlayouts}
%   command in the preamble like this: |\fxloadenvlayouts{|\meta{name}|,...}|.
%   After that, you can select any of those layouts anywhere you wish.
% \end{enumerate}
%
% \subsubsection{Available layouts\label{sec:manual:envlayoutslist}}
% Table \ref{table:envlayouts} lists the environment layouts currently
% distributed with \fx.
% \begin{itemize}

%   The \texttt{plain} environment layout prints its contents as-is, only

% \item \DescribeEnvLayout{signature}
%   The \texttt{signature} environment layout prints the author's tag (see

%   \DescribeColor{fxnote}
%   \DescribeColor{fxwarning}

%   to display its contents. It also avoids printing the annotation level,

% \item  \DescribeEnvLayout{colorsig}
%   The \texttt{colorsig} environment layout combines the features of the

% \subsection{Faces\label{sec:manual:faces}}
% In the \fx jargon, a ``face'' characterizes the visual aspect of some
% portion of text. If you're familiar with the \emacs editor, this will come
% as no surprise to you. \fx provides several faces that allow you to further
% customize the layout of annotations or their targets.
%
% \subsubsection{Setting face values}
% There are different ways to customize a face. The first one is to use the
% corresponding face option. For each face \meta{name}, their is a
% \meta{name}\texttt{face} option. For instance, the ``inline'' face is
% controlled by the \texttt{inlineface} option. Face options are
% understood by the package itself, the \cs{fxsetup} command and locally by
% all annotation commands or environments. Here is an example:
% \begin{verbatim}
% \fxsetup{inlineface=\bfseries}
% \end{verbatim}
%
% Since you will probably want to use \LaTeX{} commands in face values, you
% should know that \LaTeX{} normally can't handle such commands in package
% options. If you want this to work, you need to use the \texttt{xkvltxp}
% package first, like this:
% \begin{verbatim}
% \usepackage{xkvltxp}
% \usepackage[inlineface=\bfseries]{fixme}
% \end{verbatim}
%
% \noindent\DescribeMacro{\fxsetface}\marg{name}\marg{value}\\
% Another way to customize a face is to use the \cs{fxsetface} command by
% providing the face name and the face value as two mandatory arguments. For
% example:
% \begin{verbatim}
% \fxsetface{inline}{\bfseries}
% \end{verbatim}
%
% \subsubsection{Available faces}
% \subparagraph{The \texttt{inline} face}
% \DescribeFace{inline}
% By default, the \texttt{inline} annotation layout displays its contents in
% bold font, to distinguish the note from the surrounding text. This is
% controlled by the \texttt{inline} face whose value is \cs{bfseries} by
% default.
%
% \subparagraph{The \texttt{margin} face}
% \DescribeFace{margin}
% By default, the \texttt{margin} and \texttt{marginclue} layouts display
% their contents in footnote size. This is controlled by the \texttt{margin}
% face whose value is \cs{footnotesize} by default.
%
% \subparagraph{The \texttt{env} face}
% \DescribeFace{env}
% By default, the \texttt{plain} environment layout displays its contents in
% bold font, to distinguish it from the surrounding text. This is controlled
% by the \texttt{env} face whose value is \cs{bfseries} by default. The
% \texttt{color} and \texttt{colorsig} environment layouts honor this face as
% well, but reset it to \meta{nothing} first. You should probably keep the
% same value for the \texttt{inline} and \texttt{env} faces, since they are
% both used to display annotations within the document's body.
%
% \subparagraph{The \texttt{signature} face}
% \DescribeFace{signature}
% The \texttt{signature} environment layout honors the \texttt{env} face, and
% adds a \texttt{signature} face on top of it for the signature part. It is
% set to \cs{itshape} by default. The \texttt{colorsig} environment layout
% honors this face as well.
%
% \subparagraph{The \texttt{target} face}
% \DescribeFace{target}
% By default, the \texttt{plain} target layout displays its contents in
% italics, to distinguish it from the surrounding text. This is controlled by
% the \texttt{target} face whose value is \cs{itshape} by default. The
% \texttt{changebar}, \texttt{color} and \texttt{colorcb} target layouts honor
% this face as well, but reset it to \meta{nothing} first.
%
% \subsection{Controlling the logging of annotations}
% As well as being displayed in the document itself, all annotations are
% ``logged'' in different ways: by default, simple notes are recorded in the
% log file while the others (warnings, errors and fatal errors) are also
% displayed on the terminal output during compilation.
%
% \DescribeBooleanOption{silent}
% You have the ability to suppress logging altogether by using the
% \texttt{silent} option. This option is understood by the package itself, the
% \cs{fxsetup} command and all annotation commands and environments. Just
% as individual layout options, \texttt{silent} is a boolean option, so all
% those forms are possible: \texttt{silent}, equivalent to
% \texttt{silent=true}, and \texttt{nosilent}, equivalent to
% \texttt{silent=false} (the default).
%
% \subsection{Controlling the language of \fx\label{sec:manual:i18n}}
% \subsubsection{Available languages}
% \DescribeOption{english}
% \DescribeOption{french}
% \DescribeOption{francais}
% \DescribeOption{spanish}
% \DescribeOption{italian}
% \DescribeOption{german}
% \DescribeOption{ngerman}
% \DescribeOption{danish}
% \DescribeOption{croatian}
% \fx currently supports English (the default), French, Spanish, Italian,
% German, Danish and Croatian. You can select your preferred language by using
% the corresponding language option. These options usually appear in the call
% to \cs{documentclass} or \cs{usepackage}, but they are also understood by
% \cs{fxsetup} and all the annotation commands or environments. This
% allows you to change the selected language either globally or locally, and
% at any point in the document. The \texttt{french} and \texttt{francais}
% options are synonyms. The \texttt{german} and \texttt{ngerman} options are
% currently equivalent.
%
% \DescribeOption{lang}
% If you're manipulating language settings at the level of \fx itself (as
% opposed to the \cs{documentclass} level), then the preferred way to specify
% a language is to use the \texttt{lang} option, and give it the language name
% as a value. For instance:
% \begin{verbatim}
% \usepackage[lang=french]{fixme}
% \end{verbatim}
%
% \subsubsection{Language tracking}
% \DescribeOption{langtrack}
% If the document you're working on has parts written in different languages,
% it might be the case that \fx notes should follow the current language as
% well (especially if you're in collaborative mode; see section
% \sectionref{sec:manual:modes}). \fx provides a boolean option named
% \texttt{langtrack}. When specified, \fx assumes that you're using
% \texttt{babel} and automatically switches to the current language (as
% specified by \texttt{babel}'s \cs{languagename} command), without requiring
% an explicit language option.
%
% \DescribeOption{defaultlang}
% In the case where tracking falls on a language unsupported by \fx, a
% warning will be issued and \fx will switch to the language specified by
% the \texttt{defaultlang} option (\texttt{english} by default). If you happen
% to get one of these warnings, please consider sending me a patch with
% support for this new language (see section \sectionref{sec:code:i18n}).
%
% Finally, note that specifying a language explicitely (by means of a language
% option) in the annotation commands and environments always takes
% precedence over the language tracking behavior.
%
% \subsubsection{Indexing in different languages}
% If your document contains \fx notes written in different languages, and
% you have requested the \texttt{index} layout, \fx will not only classify
% the notes by their level of importance, but also by language. For example,
% if you have \fx warnings in both English and French, you will find two
% different subcategories for warnings in the index: one called ``Warnings''
% and one called ``Avertissements''.
%
% \subsection{Standalone or collaborative mode\label{sec:manual:modes}}
% \fx supports collaborative annotations as well as ``standalone'',
% single-author documents.
%
% \subsubsection{Standalone mode}
% By default, \fx is in standalone mode, meaning that it assumes there is
% only one person annotating the document. This has several implications on
% the layout. If you've tried it already, you may have noticed the following
% points.
% \begin{itemize}
% \item All the built-in annotation layouts (index excepted) put the \fx logo
%   in front of every note. This is also true for the environments. The idea
%   is to distinguish \fx contents from the rest of the document (for instance
%   other marginal notes or footnotes).
% \item All annotations are indexed under the main \fx category, and sorted by
%   importance level, but the \fx logo is not repeated constantly (that would
%   be useless).
% \item Similarly, the list of fixmes does not clutter itself with the logo,
%   because we already know that its contents is specific to \fx.
% \end{itemize}
% As a matter of fact, when you see the \fx logo appear somewhere, you're not
% actually contemplating it, but rather the annotation's \emph{author}. It
% just happens that by default (meaning in standalone mode), the only author
% is \fx itself.
%
% \DescribeOption{author}
% In standalone mode, you might be annoyed by this orgy of \fx logos. This
% might happen if for instance you're using the \texttt{margin} layout and you
% \emph{know} there is nothing but \fx annotations in there. In such a case,
% you will most likely want to change the author to \emph{nothing}. This can
% be acomplished by using the \texttt{author} option, which is understood by
% the package itself, the \cs{fxsetup} command and all the annotation
% commands or environments. Doing something like the following will get rid of
% the damn logo for good:
% \begin{verbatim}
% \usepackage[author=]{fixme}
% \end{verbatim}
%
% \subsubsection{Collaborative mode}
% If, on the other hand, you're working in collaboration with other people,
% every potential ``fixer'' might want to tag his or her own annotations. So
% assuming that John Doe is another author, he would most likely do something
% like this:
% \begin{verbatim}
% \fxfatal[author=JD]{rephrase this}
% \end{verbatim}
% And suddenly, John's fatal comment will be prefixed with his initials. This
% is not a very satisfactory solution however, because it would require you to
% explicitely provide the author's tag in every single note you create.
% Fortunately, \fx offers an easier way to achieve this.
%
% \paragraph{Registering new authors}
% \DescribeMacro{\FXRegisterAuthor}\marg{cmdprefix}\marg{envprefix}\marg{tag}\\
% The command \cs{FXRegisterAuthor} registers a new author with \fx. It takes
% three arguments: the last one (\meta{tag}) is just the same as the value you
% would pass to the \texttt{author} option: it will serve as a prefix (or
% signature) for John's annotations. In addition to that, a complete new set
% of user-level commands (prefixed with \meta{cmdprefix}) and environments
% (prefixed with \meta{envprefix}) will be created. To clarify, suppose that
% we have registered John like this:
% \begin{verbatim}
% \FXRegisterAuthor{jd}{ajd}{JD}
% \end{verbatim}
% Now, John can use the commands \cs{jdnote}, \cs{jdwarning} \etc, along with
% their starred versions, and he can also use the environments
% \texttt{ajdnote}, \texttt{ajdwarning} \etc, along with their starred
% versions as well. If you really want to know the whole story, it turns out
% that the main \fx interface described in section
% \sectionref{sec:manual:insertion} is created with this single line of code:
% \begin{verbatim}
% \FXRegisterAuthor{fx}{anfx}{fixme}
% \end{verbatim}
%
% \textbf{Warning!} \meta{cmdprefix} and \meta{envprefix} need to be
% different, or you will get very strange errors. The technical reason is that
% in \LaTeX, an environment named \texttt{foo} is defined in terms of two
% commands: \cs{foo} and \cs{endfoo} (yes, this is silly; the first one should
% really be \cs{beginfoo}). As a consequence, if you use the same prefix, you
% will get a name clash between the annotation commands and environments.
%
% \paragraph{Fun with the \texttt{author} option}
% Some precisions about the author option are in order here. When a new
% author is registered with \fx, the generated commands and environments
% work by \emph{presetting} the author option to the specified \meta{tag}.
% This means that it is still possible to override it explicitely like this:
% \begin{verbatim}
% \jdfatal[author=Anonymous]{For $500.00, you got your Ph.D.}
% \end{verbatim}
% I don't see any good reason for doing it though, the above example
% notwithstanding.^^A $ AUC-TeX hack to prevent math-mode
%
% The final remark is about the default \texttt{fx*} user interface: the
% \texttt{fixme} default user is special in that it is the only registered
% user to honor a global \texttt{author} option (provided in the call to
% \cs{usepackage} or \cs{fxsetup}). The intended use of this is that the
% \emph{main} author of the document uses the \texttt{fx*} interface
% (preferably with a personal \texttt{author} setting, different from the \fx
% logo), and all other authors are registered via \cs{FXRegisterAuthor}.
%
% \paragraph{Globally switching to collaborative mode}
% We're getting close, but we're not quite there yet. Perhaps you would like
% to see the tags from the different authors in the list of fixmes, or even in
% the index? Remember that \fx is in standalone mode by default, so the
% (only) tag does not appear in those places.
%
% \noindent
% \DescribeOption{singleuser}
% \DescribeOption{multiuser}
% \DescribeOption{mode}
% If you want this additional information, you've got to ask \fx to
% globally switch to collaborative mode. This can be done with either one of
% the three options \texttt{singleuser}, \texttt{mutliuser} or \texttt{mode}.
% \texttt{singleuser} and \texttt{multiuser} are boolean options. The
% \texttt{mode} option takes a value of either \texttt{singleuser} or
% \texttt{multiuser}. This is the preferred way to switch the mode. These
% options are understood globally by \cs{usepackage} or \cs{fxsetup}, and also
% locally by the annotation commands or environments.
%
% When collaborative mode is active, \fx adjusts the list of fixmes layout to
% display the authors tags as well. Additionally, \fx notes are indexed as
% before, but additional index entries, sorted by author, are generated as
% well.
%
% \subsection{Themes\label{sec:manual:themes}}
% Themes are orthogonal to layouts: they provide a way to modify the overall
% appearance of \fx by overriding the existing layouts and/or by providing new
% ones. In fact, a theme can be any kind of customization that you would
% otherwise put in your preamble.
%
% \subsubsection{Using themes}
% \DescribeOption{theme}
% The interface for using a theme is quite simple: use the \texttt{theme}
% option and give it the name of the theme you want to use. Themes are always
% external: there are none in the  core of \fx but instead they are provided
% as independent files. As a consequence, the \texttt{theme} option has the
% same usage restrictions as all the layout options we've encountered so far.
% Moreover, it is not possible to ``maintain'' several themes and switch
% between them in a single document. Themes can be loaded only in the
% preamble.
%
% \noindent\DescribeMacro{\fxusetheme}\marg{name}\\
% An alternative to the \texttt{theme} option is to use the \cs{fxusetheme}
% command, which takes the theme's name as its only mandatory argument.
%
% \subsubsection{Available themes}
% \fx comes with a number of predefined themes listed below.
%
% \paragraph{The \texttt{signature} theme}
% \DescribeTheme{signature}
% This theme uses the \texttt{signature} environment layout (see section
% \sectionref{sec:manual:envlayoutslist}), and overrides the built-in ones to
% display the author tags as a signature (\ie at the end of the annotations)
% instead of as a prefix. All original layout faces are honored.
%
% \paragraph{The \texttt{color} theme}
% \DescribeTheme{color}
% This theme uses the \texttt{color} environment and target layouts (see
% sections \sectionref{sec:manual:envlayoutslist} and
% \sectionref{sec:manual:targetlayoutslist}), and overrides the built-in ones
% to use different colors for the different annotation levels. As a
% consequence, it also avoids printing the annotation names because this
% information is already contained in the colors themselves. All original
% layout faces are honored, but the \texttt{inline} one is reset to
% \meta{nothing}. Remember that the \texttt{env} and \texttt{target} faces are
% reset as well (this is actually done by the \texttt{color} environment and
% target layouts).
%
% \paragraph{The \texttt{colorsig} theme}
% \DescribeTheme{colorsig}
% This theme combines the features of the \texttt{color} and
% \texttt{signature} ones. All original layout faces are honored, but
% the \texttt{inline} one is reset to \meta{nothing}.
%
% \section{Extending \fx}
% Hear hear, this is where you start spending more time hacking \LaTeX{} than
% actually writing your document\ldots
%
% \subsection{Modifying existing layouts}
% \fx annotations, environment and target layouts are implemented as a (set
% of) commands conforming to strict prototypes. If you're not happy with the
% way they perform, you have the possibility to \cs{renewcommand} them (in
% fact, you should use \cs{renewcommand*} for annotation and environment
% layouts). In such a case, it is probably best to have a look at the code in
% order to figure out how the original ones are written. However, a
% description of their prototypes is given below.
%
% \subsubsection{Modifying existing annotation layouts}
% \DescribeMacro[noindex]{\FXLayout\ldots}
% \marg{type}\marg{annotation}\marg{author}\\
% \DescribeMacro[noprint]{\FXLayoutInline}
% \DescribeMacro[noprint]{\FXLayoutMargin}
% \DescribeMacro[noprint]{\FXLayoutFootnote}
% \DescribeMacro[noprint]{\FXLayoutIndex}
% \DescribeMacro[noprint]{\FXLayoutMarginClue}
% Each annotation layout is implemented as a macro taking three mandatory
% arguments. By convention, this macro is named \cs{FXLayout}\meta{name}, for
% instance \cs{FXLayoutInline}.\meta{type} is the note type. It can be one of
% \texttt{note}, \texttt{warning}, \texttt{error} and \texttt{fatal}.
% \meta{annotation} is the annotation itself, and \meta{author} is the
% author's tag.
%
% \subsubsection{Modifying existing environment layouts}
% \DescribeMacro[noindex]{\FXEnvLayout\ldots Begin}
% \DescribeMacro[noindex]{\FXEnvLayout\ldots End}\marg{type}\marg{author}\\
% \DescribeMacro[noprint]{\FXEnvLayoutPlainBegin}
% \DescribeMacro[noprint]{\FXEnvLayoutPlainEnd}
% \DescribeMacro[noprint]{\FXEnvLayoutSignatureBegin}
% \DescribeMacro[noprint]{\FXEnvLayoutSignatureEnd}
% \DescribeMacro[noprint]{\FXEnvLayoutColorBegin}
% \DescribeMacro[noprint]{\FXEnvLayoutColorEnd}
% \DescribeMacro[noprint]{\FXEnvLayoutColorSigBegin}
% \DescribeMacro[noprint]{\FXEnvLayoutColorSigEnd}
% \begin{sloppypar}\noindent
%   Each environment layout is implemented as two macros taking two mandatory
%   arguments. By convention, these macros are named
%   \cs{FXEnvLayout}\meta{name}\texttt{Begin} and
%   \cs{FXEnvLayout}\meta{name}\texttt{End}, for instance
%   \cs{FXEnvLayoutPlainBegin} and \cs{FXEnvLayoutPlainEnd}.
%   \meta{type} is the note type. It can be one of \texttt{note},
%   \texttt{warning}, \texttt{error} and \texttt{fatal}. \meta{author} is the
%   author's tag.
% \end{sloppypar}
%
% \subsubsection{Modifying existing target layouts}
% \DescribeMacro[noindex]{\FXTargetLayout\ldots}\marg{type}\marg{target}\\
% \DescribeMacro[noprint]{\FXTargetLayoutPlain}
% \DescribeMacro[noprint]{\FXTargetLayoutColor}
% Each target layout is implemented as a macro taking two mandatory arguments.
% By convention, this macro is named \cs{FXTargetLayout}\meta{name}, for
% instance \cs{FXTargetLayoutPlain}. \meta{type} is the note type. It can be
% one of \texttt{note}, \texttt{warning}, \texttt{error} and \texttt{fatal}.
% \meta{target} is the textual target.
%
% \subsection{Creating new layouts}
% Creating a new layout first requires that you write new layout macros as
% described in the previous section. Once you've done that, the next step is
% to make \fx aware of this addition. This is called ``registering'' a layout.
%
% \subsubsection{Registering a new annotation layout}
% \paragraph{Early \vs late layouts} Normally, \fx typesets your annotations
% at the current position in the text, using a sensible order for built-in
% layouts. For instance, the \texttt{footnote} layout, if active, is performed
% before the \texttt{inline} one, so that the footnote mark is sticked to the
% preceding text and not to the annotation. When using targeted commands or
% environments, the situation is a bit more complex: some layouts make more
% sense at the beginning of the textual target, and some others at the end.
% The former ones are called ``early layouts'' and the later ones are called
% ``late layouts''. A typical example of an early layout is the
% \texttt{margin} one: if you're highlighting a long portion of text, it is
% more convenient to see the marginal note appear near the top of that text,
% rather than near the end of it (a nice illustration of this is to combine
% the \texttt{changebar} target layout and \texttt{margin} annotation layout).
% As for built-in layouts, only the \texttt{margin} and \texttt{marginclue}
% ones are early. All others are late. When you create a new layout, you need
% to decide whether it is an early or a late one.
%
% \paragraph{Registering late layouts}
% \begin{sloppypar}
%   \DescribeMacro{\FXRegisterLayout}\oarg{mutex}\marg{name}\marg{macro}\\
%   In order to register a late annotation layout with \fx, use the command
%   \cs{FXRegisterLayout}. This macro has two mandatory arguments: the layout
%   \meta{name} (at least 3 characters long) and the associated layout
%   \meta{macro}. For instance, the \texttt{inline} layout is registered like
%   this:
% \end{sloppypar}
% \begin{verbatim}
% \FXRegisterLayout{inline}{\FXLayoutInline}
% \end{verbatim}
% Once registered, the new layout gets a boolean option \meta{name} and is
% also recognized by the \texttt{layout} and \texttt{morelayout} options, as
% well as by the \cs{fxuselayouts} command as \meta{name}.
%
% The first (optional) argument \meta{mutex} is a comma-separated list of
% other layout names that should be in mutual exclusion with the layout we are
% registering (for example, the \texttt{margin} and \texttt{marginclue}
% layouts are in mutual exclusion). Note that mutual exclusion between two
% layouts need only be registered once. In other words, a previsouly
% registered layout will automatically be made aware of subsequent mutex
% declarations.
%
% \paragraph{Registering early layouts}
% \DescribeMacro{\FXRegisterLayout*}\oarg{boolfunc}\marg{name}\marg{macro}\\
% In order to register an early annotation layout with \fx, use the starred
% form of \cs{FXRegisterLayout}. Everything else behaves the same.
%
% \paragraph{Providing a layout}
% \DescribeMacro{\FXProvidesLayout}\marg{name}\oarg{release information}\\
% If you want to save your layout externally, you need to store it in a file
% named \texttt{fxlayout}\meta{name}\texttt{.sty} and advertise it by calling
% \cs{FXProvidesLayout}. It will then be recognized by the \cs{fxloadlayouts}
% command as \meta{name}.
%
% \subsubsection{Registering a new environment layout}
% \begin{sloppypar}
%   \DescribeMacro{\FXRegisterEnvLayout}\marg{name}\marg{begin}\marg{end}\\
%   In order to register a new environment layout with \fx, use the command
%   \cs{FXRegisterEnvLayout}. This macro has three mandatory arguments: the
%   layout \meta{name} and the associated \meta{begin} and \meta{end} macros.
%   For instance, the \texttt{color} layout is registered like this:
% \end{sloppypar}
% \begin{verbatim}
% \FXRegisterEnvLayout{color}{\FXEnvLayoutColorBegin}{\FXEnvLayoutColorEnd}
% \end{verbatim}
% Once registered, the new layout is recognized by the \texttt{envlayout}
% option and by the \cs{fxuseenvlayout} command as \meta{name}.
%
% \noindent
% \DescribeMacro{\FXProvidesEnvLayout}\marg{name}\oarg{release information}\\
% If you want to save your layout externally, you need to store it in a file
% named \texttt{fxenvlayout}\meta{name}\texttt{.sty} and advertise it by
% calling \cs{FXProvidesEnvLayout}. It will then be recognized by the
% \cs{fxloadenvlayouts} commands as \meta{name}.
%
% \subsubsection{Registering a new target layout}
% \begin{sloppypar}
%   \DescribeMacro{\FXRegisterTargetLayout}\marg{name}\marg{macro}\\
%   In order to register a new target layout with \fx, use the command
%   \cs{FXRegisterTargetLayout}. This macro has two mandatory arguments: the
%   layout \meta{name} and the associated \meta{macro}. For instance, the
%   \texttt{color} layout is registered like this:
% \end{sloppypar}
% \begin{verbatim}
% \FXRegisterTargetLayout{color}{\FXTargetLayoutColor}
% \end{verbatim}
% Once registered, the new layout is recognized by the \texttt{targetlayout}
% option and by the \cs{fxusetargetlayout} as \meta{name}.
%
% \noindent
% \DescribeMacro{\FXProvidesTargetLayout}\marg{name}\oarg{release
%   information}\\
% If you want to save your layout externally, you need to store it in a file
% named \texttt{fxtargetlayout}\meta{name}\texttt{.sty} and advertise it by
% calling \cs{FXProvidesTargetLayout}. It will then be recognized by the
% \cs{fxloadtargetlayouts} commands as \meta{name}.
%
% \subsection{Creating a new theme}
% Creating a new theme may involve anything from using (by way of
% \cs{fxsetup}) or modifying existing layouts, to providing new ones. If your
% new theme has specific layouts, you may consider writing them in seperate
% files as described before, in order to make them more generally available.
%
% \noindent
% \DescribeMacro{\FXRequireLayout}
% \DescribeMacro{\FXRequireEnvLayout}
% \DescribeMacro{\FXRequireTargetLayout}\marg{name}\\
% In order to use an external layout in a theme, use the commands
% \cs{FXRequire*Layout} and give them the layout's name as argument.
%
% \noindent
% \DescribeMacro{\FXProvidesTheme}\marg{name}\oarg{release information}\\
% A theme should be saved in a file named
% \texttt{fxtheme}\meta{name}\texttt{.sty} and advertised by calling
% \cs{FXProvidesTheme}. It will then be recognized by the \texttt{theme}
% option and the \cs{fxusetheme} command.

% \fx's language control has been described in section

% number of macros define the language-dependent part of \fx. The commands
% \cs{fx}\meta{lang}\texttt{notename}, \cs{fx}\meta{lang}\texttt{notesname},
% and their equivalent for the other note levels define the singular and
% plural forms of the note names.\\

%    \end{macrocode}
% \end{macro}
% \begin{macro}{\@fxdottedtocline}
%   \marg{tocdepth}\marg{indent}\marg{numwidth}\marg{contents}\marg{target}\\
%   This macro is copied almost verbatim from \LaTeX's core. The intent is to
%   do a similar layout, but replacing the last argument, normally a page
%   number, by arbitrary text (in our case, a note's target). The original
%   macro defines a restricted width to typeset the page number which is much
%   too short for us, so we just let the \meta{target} text take all the space
%   it needs.
%    \begin{macrocode}

%   Similar to \LaTeX's \cs{contentsline} macro, but temporarily bind
%   \cs{@dottedtocline} to our own version. The nice thing about this
%   implementation is that we can still use \cs{l@fixme} (remember that it is
%   bound to \cs{l@figure}) without exactly knowing what its definition is.

%   Wrapper around \LaTeX's \cs{addcontentsline} macro to handle the

%   normal \cs{addcontentsline} macro for reasons explained above, so we use
%   our own version of \cs{contentsline} instead. This macro is at the user

%   In order to prevent the List of Fixme's heading from being generated when

%   is performed. There's a slight bug left however: after removing the last
%   fixme note, one ends up with an empty \texttt{lox} file, so the heading
%   still appears. Previously, this was done by checking if some \fx notes
%   were given, but that was buggy: the List of Fixme's could not appear
%   before the first fixme note\ldots I should try to detect whether the file

%   \begin{enumerate}
%   \item It is possible to disable a layout by using the

% \subsubsection{Class-dependent settings}
% Currently, our class dependencies only matter in draft mode, so one could
% argue that it is not optimal to handle this here. However, it would be
% incorrect to do it in the \texttt{draft} option code because this option can
% be switched at any point in the document (remember that it is understood
% even by the annotation macros and environments) and the stuff below
% should only be executed once. Besides, \cs{@ifclassloaded} is an
% \cs{@onlypreamble} macro\ldots
%
% As documented, marginal notes are incompatible with the ACM SIG classes.
% Initially, I thought I would detect these classes and issue an error if
% marginal layout (or clue) is active. However, I changed my mind, because
% nothing prevents somebody to write a new class on top of these ones and
% authorize \cs{marginpar} back again. Normally these classes issue an error
% if \cs{marginpar} is used. However, the 2.3 / June 2007 versions are buggy
% and the error actually triggers a stack overflow in \LaTeX\ldots (patch
% submitted). Oh boy, these classes are a mess.
