% \section{Introduction}
% 
% |latex-make| is a collection of \LaTeX{} packages, scripts and
% Makefile fragments that allows to easily compile \LaTeX{} documents.
% The best feature is that \textbf{\emph{dependencies are
%     automatically tracked}}\footnote{Dependencies are tracked with
%   the help of the |texdepend.sty| package that is automatically
%   loaded: no need to specify it with |\textbackslash usepackage\{\}|
%   in your documents.}.
% \par
% These tools can be used to compile small \LaTeX{} documents
% as well as big ones (such as, for example, a thesis with summary, tables of
% contents, list of figures, list of tabulars, multiple indexes and
% multiple bibliographies).
% 
% \section{Quick start}
% 
% \subsection{First (and often last) step}
% When you want to use |latex-make|, most of the time you have to
% create a |Makefile| with the only line: \par
% \begin{source}
%     include LaTeX.mk
% \end{source}
% % Then, the following targets are available: |dvi|, |ps|, |pdf|,
% \emph{file}|.dvi|, \emph{file}|.ps|, \emph{file}|.pdf|, etc.,
% |clean| and |distclean|.
% \par
%
% All \LaTeX{} documents of the current directory should be compilable
% with respect to their dependencies. If something fails, please,
% provide me the smallest example you can create to show me what is
% wrong.
% \par\medskip
%
% \paragraph{Tip:}
% If you change the dependencies inside your document (for example, if
% you change |\include{first}| into |\include{second}|), you may have
% to type |make distclean| before being able to recompile your
% document. Else, |make| can fail, trying to build or found the old
% |first.tex| file.
% \paragraph{Shared work}
% If you work with other people that do not have installed (and do not
% want to install) \LaTeX-Make, you can use the
% |LaTeX-Make-local-install| target in |LaTeX.mk| to install required
% files in a local TEXMF tree. You can them commit this
% tree into your control version system. Then, in your |Makefile|,
% replace the single line\par
% \begin{source}
%     include LaTeX.mk
% \end{source}
% with something like\par
% \begin{source}\small
%     export TEXMFHOME:=\$(CURDIR)/relpath/to/local/tree/texmf\\
%     include \$(shell env TEXMFHOME=\$(TEXMFHOME) $\backslash$\\
%     \hspace*{12ex}kpsewhich -format texmfscripts LaTeX.mk)
% \end{source}
% If you have a previous value for |TEXMFHOME| that you do not want to
% override, you can use the following (more complexe) snipset\par
% \begin{source}\small
%     \# Adapt the following line to find the local texmf tree\\
%     LOCAL\_TEXMF:=\$(CURDIR)/\$(firstword \$(wildcard texmf $\backslash$\\
%     \hspace*{16ex}../texmf ../../texmf ../../../texmf))\\
%     \# Get the old TEXMFHOME value\\
%     TEXMFHOME:=\$(shell kpsewhich -var-value TEXMFHOME)\\
%     \# If the new tree is already in it, do nothing, else add it\\
%     ifeq (\$(filter \$(LOCAL\_TEXMF)//%,\$(TEXMFHOME)),)\\
%     TEXMFHOME := \$(LOCAL\_TEXMF)\$(addprefix :,\$(TEXMFHOME))\\
%     \# display info so that users know what to define in order to\\
%     \# compile documents directly with (pdf)latex\\
%     \$(warning export TEXMFHOME=\$(TEXMFHOME))\\
%     export TEXMFHOME\\
%     endif\\
%     ~\\
%     include \$(shell env TEXMFHOME=\$(TEXMFHOME) $\backslash$\\
%     \hspace*{12ex}kpsewhich -format texmfscripts LaTeX.mk)
% \end{source}
% Doing so, all co-authors will be able to use \LaTeX-Make without
% installing it.  However, note that:
% \begin{itemize}
% \item you wont beneficit of an update of \LaTeX-Make in your system
%   (you will continue to use the locally installed files) ;
% \item there is no support for upgrading locally installed files (but
%   reexecuting the installation should do a correct upgrade most of
%   the time) ;
% \item  if a user tries to compile the \LaTeX{} source code directly
% with |[pdf]latex|, he must before either have LaTeX-Make installed
% or define and export |TEXMFHOME|.
% \end{itemize}
%
% Another possibility is to install package files (|*.sty|) into a
% directory pointed by |TEXINPUTS|, scripts files (|*.py|) into a
% directory pointed bt |TEXMFSCRIPTS|, and to directly include
% |LaTeX.mk|. For example:
% \begin{source}\small
%     \# use local files by default\\
%     \# packages in sty/ subdir and scripts in bin/\\
%     TEXINPUTS:=sty\$(addprefix :,\$(TEXINPUTS))::\\
%     TEXMFSCRIPTS:=bin\$(addprefix :,\$(TEXMFSCRIPTS))::\\
%     export TEXINPUTS\\
%     export TEXMFSCRIPTS\\
%     \# Force using local LaTeX.mk and not system-wide LaTeX.mk if available\\
%     include \$(CURDIR)/LaTeX.mk
% \end{source}
% \subsection{Customization}
% Of course, lots of things can be customized. Here are the most
% useful ones. Look at the section \ref{sec:reference} for more detailed
% and complete possibilities.
% \par
% Customization is done through variables in the |Makefile| set
% \emph{before} including |LaTeX.mk|. Setting them after can sometimes
% work, but not always and it is not supported.\par

% 
% \variable[]{\emph{master}\texttt{\_MAIN}}%
% {Which \LaTeX{} main source for a document}%
% {figlatex\_MAIN=figlatex.dtx}%
% There is one such variable per documents declared in |LU_MASTERS|.

% If not set, \emph{master}|.tex| is used.
% 
% \variable{LU\_FLAVORS}%
% {Which flavors must be compiled}%
% {LU\_FLAVORS=DVI DVIPDF}%
% A flavor can be see as a kind of document (postscript, PDF, DVI,

% created directly from the |.tex| file (with |pdflatex|), from a
% |.dvi| file (with |dvipdfm|) or from a postscript file (with
% |ps2pdf|). This would be three different flavors.
% \par
% Some flavors are already defined in |LaTeX.mk|. Other flavors can be
% defined by the user (see section~\ref{sec:def_flavors}). The list of
% predefined flavors can be see in the table~\ref{tab:flavors}. A
% flavor can depend on another. For example, the flavor creating a
% postscript file from a DVI file depends on the flavor creating a DVI
% file from a \LaTeX{} file. This is automatically handled.
% \par
% If not set, |PS| and |PDF| are used (and |DVI| due to |PS|).

%\section{Reference manual}
%\label{sec:reference}
% 
% \subsection{Flavors}
% \subsubsection{What is a flavor ?}
% A flavor can be see as a kind of document (postscript, PDF, DVI,
% etc.) and the way to create it. Several property are attached to
% each flavor. Currently, there exists two kinds of flavors:
% \begin{description}
% \item[TEX-flavors:] these flavors are used to compile a
% \texttt{*.tex} file into a target. A \LaTeX{} compiler
% (\texttt{latex}, \texttt{pdflatex}, etc.) is used;
% \item[DVI-flavors:] these flavors are used to compile a file
% produced by a TEX-flavors into an other file. Examples of such
% flavors are all the ones converting a DVI file into another format
% (postscript, PDF, etc.).
% \end{description}
% Several properties are attached to each flavors. Most are common, a
% few a specific to the kind of the flavor.
% \begin{description}
% \item[Name:] the name of the flavor. It is used to declare dependencies
% between flavors (see below). It also used to tell which flavor
% should be compiled for each document (see the \texttt{FLAVORS}
% variables);
% \item[Program variable name:] name of the variable that will be used
%   to run the program of this flavor. This name is used for the
%   program and also for the options (variable with the
%   \texttt{\_OPTIONS} suffix);
% \item[Target extension:] extension of the target of the flavor. The
% dot must be added if wanted;
% \item[Master target:] if not empty, all documents registered for the
% flavor will be built when this master target is called;
% \item[XFig extensions to clean (\emph{TEX-flavor only}):] files
%   extensions of figures that will be cleaned for the \texttt{clean}
%   target. Generally, there is \texttt{.pstex\_t .pstex} when using
%   \texttt{latex} and \texttt{.pdftex\_t .pdftex} when using
%   \texttt{pdflatex};
% \item[Dependency \emph{DVI-flavor only}:] name of the TEX-flavor the
%   one depends upon.
% \end{description}
%
% \subsubsection{Defining a new flavor}
% \label{sec:def_flavors}
% To define a new flavor named \texttt{NAME}, one just have to declare
% a \texttt{lu-define-flavor-NAME} that calls and evaluates the
% \texttt{lu-create-flavor} with the right parameters, ie:
% \begin{itemize}
% \item name of the flavor;
% \item kind of flavor (\texttt{tex} or \texttt{dvi});
% \item program variable name;
% \item target extension;
% \item master target;
% \item XFig extensions to clean \emph{or} TEX-flavor to depend upon.
% \end{itemize}
% 
% \par
%
% For example, \texttt{LaTeX.mk} already defines:
% \paragraph{DVI flavor}
% \begin{source}[0.9\linewidth]
% define lu-define-flavor-DVI\\
% \hspace*{2ex}\$\$(eval \$\$(call lu-create-flavor,DVI,tex,LATEX,.dvi,dvi,\textbackslash\\
% \hspace*{4ex}.pstex\_t .pstex))\\
% endef
% \end{source}
% \subparagraph{Tip:} the \texttt{LATEX} program variable name means
% that the program called will be the one in the \texttt{LATEX}
% variable and that options in the \texttt{LATEX\_OPTIONS} variable
% will be used.
%
% \paragraph{PDF flavor}
% \begin{source}[0.9\linewidth]
% define lu-define-flavor-PDF\\
% \hspace*{2ex}\$\$(eval \$\$(call lu-create-flavor,PDF,tex,PDFLATEX,.pdf,pdf,\textbackslash\\
% \hspace*{4ex}.pdftex\_t .\$\$(\_LU\_PDFTEX\_EXT)))\\
% endef
% \end{source}
% 
% \paragraph{LuaLaTeX flavor}
% \begin{source}[0.9\linewidth]
% define lu-define-flavor-LUALATEX\\
% \hspace*{2ex}\$\$(eval \$\$(call lu-create-flavor,LUALATEX,tex,LUALATEX,.pdf,pdf,\textbackslash\\
% \hspace*{4ex}.pdftex\_t .\$\$(\_LU\_PDFTEX\_EXT)))\\
% endef
% \end{source}
% 
% \paragraph{PS flavor}
% \begin{source}[0.9\linewidth]
% define lu-define-flavor-PS\\
% \hspace*{2ex}\$\$(eval \$\$(call lu-create-flavor,PS,dvi,DVIPS,.ps,ps,DVI))\\
% endef
% \end{source}
% \subparagraph{Tip:} for DVI-flavors, the program will be invoked with
% with the option \texttt{-o \emph{target}} and with the name of the
% file source in argument.
% 
% \paragraph{DVIPDF flavor}
% \begin{source}[0.9\linewidth]
% define lu-define-flavor-DVIPDF\\
% \hspace*{2ex}\$\$(eval \$\$(call lu-create-flavor,DVIPDF,dvi,DVIPDFM,.pdf,pdf,DVI))\\
% endef
% \end{source}
% 
%
% \subsection{Variables}
% \label{sec:variables}
% \texttt{LaTeX.mk} use a generic mechanism to manage variables, so
% that lots of thing can easily be customized per document and/or per
% flavor.
% \subsubsection{Two kind of variables}
% \texttt{LaTeX.mk} distinguish two kind of variables. The first one
% (called SET-variable) is for variables where only \emph{one} value
% can be set. For example, this is the case for a variable that
% contain the name of a program to launch. The second one (called
% ADD-variable) is for variables where values can be cumulative. For
% example, this will be the case for the options of a program.
% \par
%
% For each variable used by \texttt{LaTeX.mk}, there exists several
% variables that can be set in the Makefile so that the value will be
% used for all documents, only for one document, only for one flavor,
% etc.

% \paragraph{SET-variable.} For each SET-variable \texttt{\emph{NAME}}, we
% can find in the Makfile:
% \begin{descvars}
%   \variable{\texttt{LU\_\emph{target}\_\emph{NAME}}}{per document
%     and per flavor value}%
%   \variable{\texttt{TD\_\emph{target}\_\emph{NAME}}}{per document
%     and per flavor value filled by the \texttt{texdepends} \LaTeX{}
%     package}%

%     value}%
%   \variable{\texttt{\emph{master}\_\emph{NAME}}}{per document
%     value}%
%   \variable{\texttt{LU\_FLAVOR\_\emph{flavor}\_\emph{NAME}}}{per
%     flavor value}%
%   \variable{\texttt{LU\_\emph{NAME}}}{global value}%
%   \variable{\texttt{\emph{NAME}}}{global value}%
%   \variable[.]{\texttt{\_LU\_\ldots\emph{NAME}}}{internal
%     \texttt{LaTeX.mk} default values}%
% \end{descvars}
% The first set variable will be used.
%
% \subparagraph{Tip:} in case of flavor context or document context,
% only relevant variables will be checked. For example, the
% SET-variable \texttt{MAIN} that give the main source of the document
% will be evaluated in document context, so only 4, 5, 6, 7 and 8 will
% be used (and I cannot see any real interest in using 6 or 7 for this
% variable).
% 
% \subparagraph{Tip2:} in case of context of index (when building
% indexes or glossary), there exists several other variables per index
% to add to this list (mainly ending with \texttt{\_{\it kind}\_{\it
%     indexname}\_{\it NAME}} or \texttt{\_{\it kind}\_{\it NAME}}).
% Refer to the sources if you really need them.
%
% \paragraph{ADD-variable.} An ADD-variable is cumulative. The user
% can replace or add any values per document, per flavor, etc.
% \begin{descvars}
%   \variable{\texttt{LU\_\emph{target}\_\emph{NAME}}}{replacing per
%     document and per flavor values}%
%   \variable{\texttt{\emph{target}\_\emph{NAME}}}{cumulative per
%     document and per flavor values}%
%   \variable{\texttt{LU\_\emph{master}\_\emph{NAME}}}{replacing per
%     document values}%
%   \variable{\texttt{\emph{master}\_\emph{NAME}}}{cumulative per
%     document values}%
%   \variable{\texttt{LU\_FLAVOR\_\emph{flavor}\_\emph{NAME}}}{replacing
%     per flavor values}%
%   \variable{\texttt{FLAVOR\_\emph{flavor}\_\emph{NAME}}}{cumulative
%     per flavor values}%
%   \variable{\texttt{LU\_\emph{NAME}}}{replacing global values}%
%   \variable{\texttt{\emph{NAME}}}{cumulative global values}%
% \end{descvars}
% \subparagraph{Tip:} if not defined, \texttt{LU\_\emph{variable}}
% defaults to ``\texttt{\$(\emph{variable})
%   \$(\_LU\_\emph{variable})}'' and \texttt{\_LU\_\emph{variable}}
% contains default values managed by \texttt{LaTeX.mk} and the
% \texttt{texdepends} \LaTeX{} package.
% \subparagraph{Example:} the ADD-variable \texttt{FLAVORS} is invoked
% in document context to know which flavors needs to be build for each
% document. This means that \texttt{LU\_{\it master}\_FLAVORS} will be
% used.
% \begin{source}
%   \# We override default value for MASTERS\\
%   LU\_MASTERS=foo bar baz\\
%   \# By default, only the DVIPDF flavor will be build\\
%   FLAVORS=DVIPDF\\
%   ~\\
%   bar\_FLAVORS=PS\\
%   LU\_baz\_FLAVORS=PDF\\
%   \# there will be rules to build\\
%   \# * foo.dvi and foo.pdf\\
%   \# ~ (the DVIPDF flavor depends on the DVI flavor)\\
%   \# * bar.dvi, bar.pdf and bar.ps\\
%   \# ~ (the PS flavor is added to global flavors)\\
%   \# * baz.pdf\\
%   \# ~ (the PDF flavor will be the only one for baz)
%   include LaTeX.mk
% \end{source}
% \subsubsection{List of used variables}
% Here are most of the variables used by \texttt{LaTeX.mk}. Users
% should only have to sometimes managed the first ones. The latter are
% described here for information only (and are subject to

% \begin{question}{No rule to make target `LU\_WATCH\_FILES\_SAVE'}{When
%   using |LaTeX.mk|, I got the error:\\
%   |make[1]: *** No rule to make target `LU\_WATCH\_FILES\_SAVE'. Stop.|}
%
% |make| is called in such a way that does not allow correct recursive
% calls. As one can not know by advance how many times \LaTeX{},
% bib\TeX{}, etc. will need to be run, |latex-make| use recursive
% invocations of |make|. This means that in the |LaTeX.mk| makefile,
% there exist rules such as:
% \begin{source}
%   \$(MAKE) INTERNAL\_VARIABLE=value internal\_target
% \end{source}
% In order |latex-make| to work, this invocation of |make| must read
% the same rules and variable definitions as the main one. This means
% that calling "|make -f LaTeX.mk foo.pdf|" in a directory with only
% |foo.tex| will not work. Recursive invocations of make will not load
% |LaTeX.mk|, will search for a |Makefile| in the current directory
% and will complain about being unable to build the
% |LU_WATCH_FILES_SAVE| internal target.
% 
% \par\medskip
% The solution is to call |make| so that recursive invocations will
% read the same variables and rules. For example:\\
% |make -f LaTeX.mk MAKE="make -f LaTeX.mk" foo.pdf|\\
% or (if there is no |Makefile| in the directory):\\
% |env MAKEFILES=LaTeX.mk make foo.pdf|\\
