+Nota : this packages requires pdfTeX.
+
+The linegoal package provides a macro \linegoal
+to be used with \setlength :
+   \setlength<some dimen>\linegoal
+
+will assign to <some dimen> the horizontal length
+of the remainder of the line.
+
+This is achieved using the \pdfsavepos primitive
+and the zref-savepos package.
+
+-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+Typical usage :
+
+Some text: \begin{tabularx}\linegoal{|l|X|} \hline
+            one & two                       \\
+            three & four                    \\\hline
+           \end{tabularx}

+%
+% \thispackage provides a single macro: \cs\linegoal \, which expands to the dimension of the remainder of the line.
+% It requires \hologo{pdfTeX} (or \hologo{XeTeX}) for its \cs\pdfsavepos primitive.
+% With \hologo{pdfTeX}, \cs\pdfsavepos works in \textt{pdf} mode (\cs\pdfoutput$>0$) \textbf{and also in} \textt{dvi} mode (\cs\pdfoutput$=0$).
+% Two compilations (at least) are necessary to get the correct ``line goal''.§
+% {\centering\extrarowsep=.3\parskip

+% Saying:       &\cs\somedimen = \cs\linegoal    \quad\footnote{Note that only this syntax allows the \cs\global preffix in case the \XPackage{calc} package is loaded.}      \\
+% or:           &\cs\setlength \cs\somedimen \M*{\cs\linegoal}
+% \end{tabu*}
+% \par
+% }
+%
+% sets \cs\somedimen to be the (horizontal) length from the current position to the right margin. This can be useful for
+% use with \XPackage{tabu},\, \XPackage{tabularx},\, or\, \textt{tabular\stform*}\, for example.§
+% {\centering\extrarowheight\parskip
+% \begin{tabu} to\linewidth{@{}lX}
+% At first run:  &\cs\linegoal expands to \cs\linewidth and writes the correct line goal into the \xext{aux} file. \\
+% Other runs:    &\cs\linegoal expands to the value read in the \xext{aux} file and (eventually) updates the
+%                  correct line-goal into the \xext{aux} file, if the value has changed.
+% \end{tabu}\par}
+%
+% Limitation when using \cs\linegoal inside \xpackage{calc} of \hologo{eTeX} expressions:
+%
+% If \cs\linegoal is used inside an expression with \cs\dimexpr, \cs\glueexpr or
+% inside \cs\setlength (package \xpackage{calc}), then \cs\linegoal \textbf{must appear at the very last position in the expression}:
+%
+% \begin{tabu*}spread0pt .{X}\}
+% \begin{Verbatim}
+%   \begin{tabu} to\dimexpr-2in + .5\linegoal{XX} ....
+%   \setlength \dimen@ {-2in + .5\linegoal}
+%   \end{tabu}
+% \end{Verbatim}
+%\end{tabu*}
+%\,  are admissible.
+%
+% \thispackage requires \hologo{pdfTeX} (in \textt{pdf} or \textt{dvi} mode)
+% or \hologo{XeTeX} and the module \xpackage{zref-savepos} of \XPackage{zref}.

+% \label{userinterface}
+%
+% \subsection{\cs{linegoal}: a macro which behaves mostly like a \textt{dimen}}
+%
+% \begin{declcs}{linegoal}
+% \end{declcs}
+%
+% The first aim of \cs\linegoal is to give a facility to get the length of the remainder of the line.
+% This is possible with \hologo{pdfTeX} and its \cs\pdfsavepos primitive (which is supplied by \hologo{XeTeX} as well).
+% For convenience, \thispackage loads and uses the \xpackage{zref-savepos} package from H. Oberdiek.
+%
+% \cs\pdfsavepos is supplied by \hologo{pdfTeX} (and \hologo{XeTeX}) in both \textt{pdf} and \textt{dvi} modes.
+% If the document is not compiled with \hologo{pdfTeX} or \hologo{XeTeX} then \cs\linegoal will expand to \cs\linewidth
+% in any case.
+%
+% {\fontname\font \hologo{XeTeX} {\changefont{fam=cmr}\hologo{XeTeX}}}
+%
+% \begin{VerbLines}[commandchars=£()]
+% This is a tabularx that fills the remainder of the line:
+%     \begin{tabularx}(£rred(\linegoal)){|l|X|}\hline
+%        Something & Something else \\
+%        Something & Something else \\\hline
+%     \end{tabularx}
+% \end{VerbLines}
+%
+% \textbf{Typical application is for tabulars of variable width} like \CTANentry{tabularx} or \CTANentry{tabu}.
+% Package \TabU has a \textt{linegoal} option to use \cs\linegoal as the default target for the whole tabular.
+%
+%
+% This is a \textt{tabularx} that fills the remainder of the line:
+% \begin{tabularx}\linegoal{|l|X|}\hline
+%  Something & Something else \\
+%  Something & Something else \\\hline
+% \end{tabularx}
+%
+% {\smaller
+% \begin{lstlisting}[caption={This is a \env{tabu} that fills the half of the remainder of the line}]
+% \tabulinestyle{red}
+% $\begin{tabu} to .5\linegoal {|X[$c]|X[2$c]|} \tabucline-
+% \alpha & \beta \\  \tabucline[on2pt red]-
+% \gamma & \delta \\ \tabucline-
+% \end{tabu}$
+% \end{lstlisting}
+% }
+%
+% This is a \textt{tabu} that fills the half of the remainder of the line:
+% {\tabulinestyle{red}
+%     $\begin{tabu}to .5\linegoal{|X[$c]|X[2$c]|} \tabucline-
+%        \alpha & \beta    \\ \tabucline[on 2pt,red]-
+%        \gamma & \delta   \\ \tabucline-
+%     \end{tabu}$
+% }
+%
+% Please, refer to \CTANentry{tabu} documentation
+% for more information on the preamble and the command \cs\tabucline used here as an example.
+%
+% \subsection{The \textt{verbose} package option}
+%
+% You can load \thispackage with the \M*[verbose] option to get the line-goals
+% as information in the \xext{log} file.
