+% \end{abstract}
+%
+% \section{Introduction}
+%       This package provides a shorter version of some accents-making
+%	commands, particularly suited for italian language.
+%
+%       In particular some commands are redefined, so care should be
+%       taken, expecially when including this package in an already
+%       existent \LaTeX{} file.
+%
+%       \noindent
+%       The redefined commands are:\\
+%	``|\a|", ``|\i|", ``|\o|" and ``|\u|",\\
+%	whos job can now be done by the commands\\
+%	``|\oFinnick|" (finnick ``o" bar),
+%	``|\DotlessI|" (dotless ``i", for accents),
+%	``|\aAccent|" (for accents in |tabbing| environment)
+%	and ``|\uAccent|" (upsidedown ``hat" accent).
+%
+% \section{Required packages}
+%
+%	This package requires the ``|\xspace|" command provided by
+%	the ``|xspace|" package.
+%
+% \section{Options}
+%
+%	This package provides the options ``|ExtdChar|" and
+%	``|ExtdCharOnly|" which allow the use of the special
+%	chars ``\`a", ``\`e", ``\`\i", ``\`o", ``\`u" and ``\'e"
+%	as accents-making commands.
+%	The second options also inhibits the definitions of
+%	``|\a|", ``|\e|", ``|\i|", ``|\o|", ``|\u|", ``|\ee|"
+%	and ``|\che|" as short forms of the accent-commands
+%	(it is particularly useful for non-Italian documents).
+%
+% \section{Accents}
+%
+%	Unless you specify the ``|ExtdCharOnly|" option, the
+%	commands ``|\a|", ``|\e|", ``|\i|", ``|\o|", ``|\u|" and ``|\E|"
+%       prints the corresponding letter with a grave accent;
+%       the commands ``|\ee|" and ``|\che|" print the letter ``|e|"
+%       or the three letters ``|che|" with an acute accent (i.e. ``\'e"
+%	and ``ch\'e").
+%
+%	Moreover, if the ``|ExtdChar|" or ``|ExtdCharOnly|" option was
+%	used, the chars ``\`a", ``\`e", ``\`\i", ``\`o", ``\`u" and ``\'e"
+%	are equivalent to the commands ``|\`a|", ``|\`e|", ``|\`\i|",
+%	``|\`o|", ``|\`u|" and ``|\'e|".

+%	\begin{macro}{Accents}
+%	A trick adapted from the |doc| package (which, perhaps, may be
+%	done in a better way) is used (if the ``|ExtdChar|" option was
+%	selected) to associate the extended-ASCII chars which represents
+%	accents with the corresponding accent-making commands.

+% \section{Introduction}
+%	This package provides the font ``|\DblFont|" (font |msbm10|), which
+%	corresponds to the so called blackdoard-bold symbols.
+%
+% \section{The options}
+%	For each uppercase letter ``|X|" a corresponding ``|X|" and ``|XX|"
+%	options exist: they declare the command ``|\X|" and ``|\XX|" which
+%	generates the letter |X| in |DblFont|.
+%	If a command named ``|\X|" or ``|\XX|" already exists in \LaTeX{},
+%	their definition is first saved in ``|\BackDoubleX|" or
+%       ``|\BackDoubleXX|", respectively.
+%
+%	\noindent
+%	Also a ``|RT|" option exists: it declares the ``|\RT|" command,
+%	which generates the two letters |RT| in |DblFont| (used for the
+%	Raviart-Thomas spaces).

+%
+% \begin{abstract}
+%	Documentation for the package \texttt{\FileName}.
+% \end{abstract}
+%
+% \section{Introduction}
+%	This package provides some commands to make the use of graphic
+%	files in \LaTeX{} simpler.
+%
+%	\noindent
+%	It declares the ``|Figure|" environment (capitalized!) and
+%	the two commands ``|\graphfile|" and ``|\graphfile*|".
+%	Combining this commands, it it possible to include graphic
+%	files in a \LaTeX{} document very simply.
+%
+% \section{Required packages}
+%	This package uses the ``|\includegraphics*|" command defined in the
+%	standard |graphics| package.
+%	Moreover, it uses the package |subfigure| when the |subfigure|
+%	option is specified, and the |float| package if the |AllowH|
+%	option is used.
+%
+% \section{The options}
+%	At now, two options are available: ``|subfigure|" and ``|AllowH|".
+%
+%	\noindent
+%	The ``|subfigure|" option allow the use of sub-figures
+%	inside a |Figure| environment, in order to place multiple
+%	pictures in a single \LaTeX{} figure (cfr. the |subfigure|
+%	standard package).
+%
+%	\noindent
+%	The ``|AllowH|" option allow the use of the ``|H|" float specifier
+%	for the |Figure| environment, in order to place the figure exaclty
+%	where the command is placed (cfr. the |float| standard package).
+%
+% \section{The \texttt{Figure} environment and its relatives}
+%	The ``|Figure|" environment (capitalized!) is somewhat different
+%	from the standard \LaTeX{} ``|figure|" environment: besides an
+%	optional argument used to specify the placement parameters (which
+%	now defaults to ``|[htbp]|"), it has a mandatory agrument specifying
+%	the ``caption" and another optional argument, used as a ``label" for
+%	cross-referencies:
+%
+%	\begin{verbatim}
+%		\begin{Figure}[<htbpH>]{<caption>}[<label>]
+%		            ...
+%		\end{Figure}
+%	\end{verbatim}
+%
+%	\noindent
+%	The use of the ``|H|" specifier (i.e. ``I want my float here!") is
+%	possible only if the ``|AllowH|" option has been specified.
+%
+% \subsection{The \texttt{graphfile} command}
+%	Inside the ``|Figure|" environment, are available the commands:
+%
+%	\begin{verbatim}
+%		\graphfile[<width>]{<file>}[<sub-caption>]
+%		\graphfile*[<heigth>]{<file>}[<sub-caption>]
+%	\end{verbatim}
+%
+%	\noindent
+%	which are a simplified version of the ``|\includegraphics*|"
+%	command (which is automatically included by this package; see the
+%	|graphics| package for reference), since you don't have to worry
+%	about scaling: the mandatory argument is the name of the graphic file to
+%	include, whereas the first optional argument specifies the desired
+%	width (in the non *-form) or heigth (in the *-form) of the figure as
+%	a fraction of ``|\linewidth|" (e.g. ``|50|" means ``|.50\linewidth|",
+%	i.e. half a line! ), so no unit of measure (as ``|cm|" or ``|pt|")
+%	is required.
+%	Moreover, since the ``*-form" of ``|\includegraphics|" is used, the
+%	regions outside the bounding-box are not drawn.
+%	Another advantage of the combined use of the ``|Figure|" environment
+%	and the ``|\graphfile|" commands is that the picture is automatically
+%	centered horizontally, so no ``|\centering|" or similar declartion
+%	is required.
+%
+%	\begin{verbatim}
+%		\begin{Figure}[<htbpH>]{<caption>}[<label>]
+%		        \graphfile[<width>]{<file>}
+%		\end{Figure}
+%	\end{verbatim}
+%
+% \subsection{Sub-figures}
+%
+%	If you want to include more than one file in a single figure,
+%	you need to specify the ``|subfigure|" option, which includes the
+%	|subfigure| package and provides the authomatic placement of a
+%	sub-caption below each picture.
+%
+%	\begin{verbatim}
+%		\graphfile[<width_1>]{<file_1>}[<sub-caption_1>]
+%			...
+%		\graphfile[<width_N>]{<file_N>}[<sub-caption_N>]
+%	\end{verbatim}
+%
+%	\noindent
+%	which is a combined version of ``|\subfigure|" and ``|\includegraphics*|"
+%	(see the |subfigure| and |graphics| packages for reference):
+%	the last optional argument specify a ``caption" for the sub-figure under
+%	consideration, while the first two arguments work exactly like as
+%	described above in the case of one only picture (indeed, you can
+%	use the last optional argument even if the |subfigure| option was
+%	not specified, in which case it is simply ignored).
+%	Each individual caption is printed preceded by a bracketed letter,
+%	which is the sub-figure counter and is printed even if no caption is
+%	specified.
+%	Using only a series of ``|\graphfile[|$\dots$|]{|$\dots$|}[|$\dots$|]|"
+%	commands inside a ``|Figure|" environment provides an equal spacing
+%	beetween the pictures and around them, without the need for any
+%	extra command.
+%	Finally, if a ``|<label>|" was specified as the last optional argument
+%	to the ``|Figure|" environment, you can reference to each individual
+%	sub-figure by the labels ``|<label>:a|", ``|<label>:b|", and so on,
+%	without the need for declaring them.
+%
+%	\begin{verbatim}
+%		\begin{Figure}[<htbpH>]{<caption>}[<label>]
+%			\graphfile[<width_1>]{<file_1>}[<sub-caption_1>]
+%			\graphfile[<width_2>]{<file_2>}[<sub-caption_2>]
+%			       :
+%			       :
+%		\end{Figure}
+%	\end{verbatim}
+%
+% \subsection{The \texttt{FigureDefaultPlacement} command}
+%
+%	The command ``|FigureDefaultPlacement{|$\dots$|}|'' can be used to
+%	specify the default value for the placement argument of the ``|Figure|''
+%	environment.
+%	This is useful to change the default placement from the standard
+%	value ``htbp''.

+%
+% \begin{abstract}
+%	Documentation for the package \texttt{\FileName}.
+% \end{abstract}
+%
+% \section{Introduction}
+%	This package provides some useful math-commands which are simpler
+%	to use and prettier then their standard \LaTeX{} counterpart.
+%
+%	In particular the ``|\d|" command is redefined, so
+%	care should be taken, expecially when including this package in an
+%	already existent \LaTeX{} file.
+%
+%	\noindent
+%	The original work of ``|\d|" (i.e. place a dot under its argument)
+%	is now done by the ``|\UnderDot|" command.
+%
+% \section{The options}
+%	At now, six options are available with the \texttt{\FileName}
+%	package, which comes out in matched pairs.
+%
+%	\noindent
+%	The ``|ThreeSubscrSum|" and ``|TwoSubscrSum|" options control the
+%	placement of subscripts for the ``|\Sum|" command: the latter
+%	(which is the default) puts the index under the simbol toghether
+%	with the starting point, while the former puts the index on the
+%	lower right corner.
+%
+%	\noindent
+%	The ``|ProdVettWedge|" and ``|ProdVettTimes|" options select
+%	which symbol is to be used for the \emph{vector product}: the first
+%	one uses a ``|\wedge|" (default), whilst the second uses a
+%	``|\times|".
+%
+%	\noindent
+%	Finally, the ``|VectOpStr|" and ``|VectOpSymb|" options controls
+%	whether the vector-operator commands ``|\Grad|", ``|\Div|" and
+%	``|\Rot|" should produce a roman string (default) or a
+%	``|\nabla|" symbol followed by an operator, respectively.
+%
+% \section{Math-mode commands}
+%	The \texttt{\FileName} package defines a number of math-mode
+%	commands.
+%
+%	\subsection{The \texttt{text} command}
+%		The ``|\text{|\ldots|}|" command is defined to be
+%		equivalent to ``|\mbox|" (except when the ``|amstext|"
+%		package is also used, since this package already defines
+%		this command in a better way).
+%
+%		\noindent
+%		It is intended for inserting pieces of text in a formula.
+%
+%	\subsection{Commands for doing integrals}
+%		The ``|\Int|" (capitalized) differs from the \LaTeX{}
+%		command ``|\int|" in that it is always printed in
+%		|displaystyle| and if it has only a subscript, this is
+%		somewhat lowered so that it looks better.
+%		\begin{verbatim}
+%		   \Int_{...}^{...}	  ...	   \d{...}
+%		\end{verbatim}
+%
+%		The ``|\d{|\ldots|}|" command is for making the
+%		differential symbol at the end of integrals: it simply
+%		prints a ``|d|" followed by its argument and preceded by
+%		a little space, which seems prettier.
+%
+%	\subsection{Commands for making sums}
+%		The ``|\Sum{|$\cdots=\cdots,\cdots$|}|" command works
+%		differently, depending on which option between
+%		``|TwoSubscrSum|" (default) and ``|ThreeSubscrSum|" has
+%		been specified.
+%
+%		\noindent
+%		In the first case, it expands to
+%		``|\displaystyle\sum_{...=...}^{...}|", whereas in the
+%		second case the second and third argument are treated
+%		in the same way as before (i.e. as a subscript and
+%		superscript, respectively), but the first argument
+%		(the one before the ``=") is placed near
+%		the lower-left edge of the ``|\sum|" symbol and the ``="
+%		is not printed.
+%
+%		There is also a ``|\SUM{|\ldots|}|" command which is useful
+%		when only a subscript is desired, irrespectively of the
+%		option specified: in fact, is is equivalent to
+%		``|\displaystyle\sum_{|\ldots|}|".
+%
+%	\subsection{Derivatives symbols}
+%		The commands ``|\DerTot{|\ldots|}{|\ldots|}|",
+%		``|\DerPar{|\ldots|}{|\ldots|}|" and ``|\DerNorm{|\ldots|}|"
+%		generate the symbols of total derivative, partial derivative
+%		and normal derivative, respectively.
+%
+%		\noindent
+%		In other words, they are the same as:
+%		\begin{verbatim}
+%		   \displaystyle\frac{d...}{d...}
+%		   \displaystyle\frac{\partial ...}{\partial ...}
+%		   \displaystyle\frac{\partial ...}{\partial n}
+%		\end{verbatim}
+%
+%	\subsection{Arrow-limits commands}
+%		The command ``|\TendsTo|[$\cdots,\cdots$]" generates a
+%		right-arrow with optionally an underscript wich is another
+%		smaller right-arrow between the two comma-separeted
+%		arguments inside the square brackets.
+%
+%		\noindent
+%		For example, the command ``|f(x) \TendsTo[x,0] 1|" generates
+%		the following output:
+%		$f(x) \mathop{\longrightarrow}\limits_{x \rightarrow 0} 1$.
+%
+%	\subsection{Vector-operators commands}
+%		Finally, the commands ``|\Grad|", ``|\Div|" and
+%		``|\Rot|" generates the strings ``grad", ``div" and ``rot"
+%		in roman type and with small spaces added before and after,
+%		if the ``VectOpStr" option is in effect (default).
+%		If, instead, the option ``VectOpSymb" was specified, they
+%		generate ``|\nabla|", ``|\nabla\cdot|" and
+%		``|\nabla\ProdVett|" respectively.
+%
+%		The command ``|\ProdVett|" is intended for making the
+%		symbol of vector product, and evaluates to ``|\times|"
+%		with the option ``ProdVettTimes" and to ``|\wedge|" with
+%		the (default) option ``ProdVettWedge".
+%
+%		\begin{tabular}{lcccc}
+%			&	&  |VectOpStr|	& \multicolumn{2}{c}{|VectOpSymb|}	\\
+%			&		&		&|ProdVettWedge|&|ProdVettTimes|\\
+%		 |\Grad|& $\Rightarrow$ & $\mathrm{grad}$& $\nabla$	& $\nabla$	\\
+%		 |\Div|	& $\Rightarrow$ & $\mathrm{div}$& $\nabla\cdot$	& $\nabla\cdot$	\\
+%		 |\Rot|	& $\Rightarrow$	& $\mathrm{rot}$& $\nabla\wedge$& $\nabla\times$
+%		\end{tabular}

+%
+% \begin{macro}{\text}
+%	The definition of |\text| is deferred at the |\begin{document}|,
+%	so that if the \texttt{amstext} package is loaded (even after this
+%	package), its definition of text will be used, since it seems
+%	better.
+%    \begin{macrocode}
+%%
+\AtBeginDocument{\ifx\undefined\text \def\text#1{\ \mbox{#1}\ } \fi}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\Int}
+%	The command |\@INT@sub@SUP| has one argument and then a mandatory
+%	superscript: il typesets an integral symbol (in |\displaystyle|)
+%	with the argument as a lower-bound and the superscript as an
+%	upper-bound.
+%    \begin{macrocode}
+%%
+\def\@INT@sub@SUP#1^#2{{\displaystyle\int_{#1}^{#2}}}
+%    \end{macrocode}
+%	The command |\@INT@subONLY| has only an argument, which is used as
+%	as a subscript for a |displaystyle| |\int|, but lowered of |0.2ex|.
+%    \begin{macrocode}
+\def\@INT@subONLY#1{{\displaystyle\int_{\raisebox{-0.2ex}{$_{#1}$}}}}
+%    \end{macrocode}
+%	The command |\@INT@sub| must have a subscript and may optionally be
+%	followed by a superscript.
+%    \begin{macrocode}
+\def\@INT@sub_#1{\@ifnextchar^{\@INT@sub@SUP{#1}}{\@INT@subONLY{#1}}}
+%    \end{macrocode}
+%	The command |\@INT@SUP@sub| must have a superscript and a subscript,
+%	in that order: they are passed to a |displaystyle| |\int| command.
+%    \begin{macrocode}
+\def\@INT@SUP@sub^#1_#2{{\displaystyle\int_{#2}^{#1}}}
+%    \end{macrocode}
+%	The |\Int| command invokes |\@INT@SUP@sub| or |\@INT@sub| or simply
+%	expands to |\displaystyle\int| depending on what follows (|^|, |_|
+%	or neither of them).
+%    \begin{macrocode}
+\newcommand{\Int}{\@ifnextchar^{\@INT@SUP@sub}{\@ifnextchar_{\@INT@sub}{\displaystyle\int}}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\d}
+%	The original |\d| command is saved in |\UnderDot|, then (at the
+%	|\begin{document}| to avoid conflicts with other packages) it is
+%	redefined as a ``|d|" preceeded by some space an followed by its
+%	argument (it is intended for printing the differential symbol at
+%	the end of an integral).
+%    \begin{macrocode}
+%%
+\AtBeginDocument{ \let\UnderDot=\d \renewcommand{\d}[1]{\:\:d#1} }
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\Sum}
+%	The command |\INNER@SUM| is defined differently depending on the
+%	selected option. It has 3 or 2 orguments, ended by an exclamation
+%	mark and separated by an equal sign and a comma.
+%	The two last arguments are passed as a subscrit and as a superscript
+%	to a |displaystyle| |\sum|, whereas the first argument (if they are
+%	3) is typeset in |scriptstyle| and lowered so that it occours at the
+%	lower right corner of the |sum| symbol.
+%    \begin{macrocode}
+%%
+\if@ThreeSubscrSum
+  \def\INNER@SUM#1=#2,#3!{{\displaystyle\sum_{#2}^{#3}\raisebox{-0.6ex}{$_{\!#1}$}}}
+\else
+  \def\INNER@SUM#1,#2!{{\displaystyle\sum_{#1}^{#2}}}
+\fi
+%    \end{macrocode}
+%	The |\Sum| command is then simply a call to |\INNER@SUM|, with a
+%	question mark added to denote the end of the argument.
+%    \begin{macrocode}
+\newcommand{\Sum}[1]{\INNER@SUM#1!}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\SUM}
+%	The |\SUM| command has one only argument which is used as a
+%	subscript and, again, is always printed in |\displaystyle|.
+%    \begin{macrocode}
+\newcommand{\SUM}[1]{{\displaystyle\sum_{#1}}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\DerPar}
+%	The commands ``|\DerPar|", ``|\DerTot|" and ``|\DerNorm|" generate a
+%	|displaystyle| |\frac| command, with a ``|\partial|" or ``|d|" or
+%	``|\partial n|" added to its arguments and followed by a little space.

+% \end{abstract}
+%
+% \section{Introduction}
+%	This package provides some useful math-commands and enviroments,
+%	which are simpler to use and prettier then their standard \LaTeX{}
+%	counterpart.
+%
+%	In particular some commands are redefined\footnote{See the options
+%	in next section if you don't want these comand to be redefined}, so
+%	care should be taken, expecially when including this package in an
+%	already existent \LaTeX{} file.
+%
+%	\noindent
+%	The redefined commands are:\\
+%	|\(|, |\)|, |\[|, |\]|, |\{| and |\}|	\\
+%	The effect of ``|\(| \dots |\)|" can still be achieved by the
+%	\LaTeX{} equivalent commands ``|\begin{math}| \dots |\end{math}|"
+%	or ``|$| \dots |$|".
+%
+%	\noindent
+%	Similarly, the effect of ``|\[| \dots |\]|" can be achieved by
+%	the \LaTeX{} equivalent commands
+%	``|\begin{displaymath}| \ldots |\end{displaymath}|"
+%	or ``|$$| \dots |$$|".
+%
+%	\noindent
+%	The ``|\{|" and ``|\}|" commands are the more error-prone, since
+%	one may try to use ``|\left\{|", which now is incorrect, because
+%	the ``|\{|" command already contains a ``|\left|" declaration.
+%	In the rare occasions where a brace of normal size is needed, one
+%	can use the \LaTeX{} commands ``|\lbrace|" and ``|\rbrace|"
+%
+%	\noindent
+%	Also the ``|equation|" environment has been changed, but it is
+%	completly compatible with the original definition, so it should
+%	be safe, perhaps except when the first character of the equation
+%	is an open square bracket or it is placed in a moving argument:
+%	in fact, the new version of this command is fragile, and this is
+%	true also for most of the commands defined by this package.
+%
+% \section{The options}
+%	At now, five options are available with the \texttt{\FileName}
+%	package.
+%
+%	\noindent
+%	The ``|RedefEquation|"/``|StdEquation|" and
+%	``|RedefBrackets|"/``|StdBrackets|" options control
+%	whether the ``|equation|" environment and the brace commands
+%	``|\(|", ``|\(|", ``|\)|", ``|\[|", ``|\]|", ``|\{|" and ``|\}|
+%	should be redefined or retain their original \LaTeX{} meaning.
+%	More precisely, ``|RedefEquation|" (default) redefines the
+%	``equation" environment to have an optional argument (used as a
+%	label), while ``|StdEquation|" leaves it unchanged. In the first
+%	case, the ``equation" environment will be equivalent to the
+%	``Equation" environment (capitalized!) described below, whereas in
+%	the second case they will be different.
+%	Similarly, the ``|RedefBrackets|" option (default) makes the
+%	brackets command to be redefined, whilst ``|StdBrackets|" leave
+%	them their original meaning.
+%	Also a ``|Standard|" option exists, which amounts to specify both
+%	the ``|StdEquation|" and ``|StdBrackets|" options, thus making the
+%	package fully standard, which may be useful when sending your
+%	\LaTeX{} files to someone else.
+%
+% \section{Math-mode environments}
+%	This package provides three math-mode environments, each with a
+%	``*-form" which does not generates numbers.
+%
+%	\subsection{The \texttt{Equation} environment}
+%		The ``|Equation|" environment has an optional argument
+%		which is used as a label to reference it.
+%		\begin{verbatim}
+%			\begin{Equation}[label]
+%			        ...
+%			\end{Equation}
+%		\end{verbatim}
+%		If the ``|RedefEquation|" option is in effect (default),
+%		then the ``|equation|" environment is redefined to have
+%		the same optional argument as ``|Equation|".
+%
+%		There is also a *-form, which does not generate a number
+%		(so this *-form is really a ``displaymath" and not an
+%		equation, but it has been added for simmetry and for making
+%		it easier to add or remove the number to a formula).
+%
+%		\noindent
+%		The *-form has an optional argument like the non-* form,
+%		which is disregarded by the environment and is added only
+%		for simmetry reasons.
+%		\begin{verbatim}
+%			\begin{equation*}[disregarded-label]
+%			        ...
+%			\end{equation*}
+%		\end{verbatim}
+%
+%	\subsection{The \texttt{MultiLine} equation environment}
+%		The ``|MultiLine|" environment is intended for formulas
+%		that don't fit on a single line, and so must be broken
+%		across lines.
+%
+%		\noindent
+%		As for the |Equation| environment above, it has an optional
+%		argument which is used as a label.
+%
+%		\noindent
+%		All the lines but the first are automatically indented by
+%		the lenght ``|\MultiLineIndent|", which is rougthly what
+%		one expects, but can be changed at any time by the user
+%		with ``|\setlenght{\MultiLineIndent}{...}|".
+%		You can also control the alignment of the continuation rows
+%		by placing an optional |&| in the first row: is such a case
+%		all the others line will \emph{not} be indented
+%		by ``|\MultiLineIndent|" but wil behave \emph{as if} there
+%		there were an ampersand in front of them (i.e. they will be
+%		left-aligned at the right of the \& in the first row).
+%
+%		\noindent
+%		Each line but the last must end with a ``|\\|" command
+%		(which can have an optional argument to add some vertical
+%		space between lines).
+%		When the line is broken in the middle (e.g. after a ``+"
+%		sign) and not at the end (i.e. after a ``=" or similar), the
+%		*-form ``|\\*|" may be used to indicate the line-break, the
+%		difference being in an extra space added at the beginning of
+%		the next line.
+%		The width of a thise space defaults to 1em and can be changed
+%		by the user with ``|\setlenght{\MultiLineStarIndent}{...}|".
+%
+%		\begin{verbatim}
+%			\begin{MultiLine}[label]
+%			      ... [&]= ... =   \\
+%			             = ... +   \\*
+%			               + ... = \\
+%			             = ...
+%			\end{MultiLine}
+%		\end{verbatim}
+%
+%		Also this environment has a *-form which differs only in that
+%		it does not generate an equation number.
+%		\begin{verbatim}
+%			\begin{MultiLine*}[disregarded-label]
+%			      ... [&]= ... =   \\
+%			             = ... +   \\*
+%			               + ... = \\
+%			             = ...
+%			\end{MultiLine*}
+%		\end{verbatim}
+%
+%	\subsection{The \texttt{System} environment}
+%		The ``|System|" environment is used for grouping a set of
+%		equations together inside a left brace, with one only
+%		equation number.
+%
+%		\noindent
+%		Again there is an optional argument to indicate a label and
+%		each equation is separated by a ``|\\|" or ``|\\*|" command,
+%		as for the ``|MultiLine|" environment.
+%
+%		\noindent
+%		The rows (except the ones ended with the *-form ``|\\*|")
+%		may optionally contain one ``|&|", which is usually used
+%		when some text should be added to the equation.
+%			\begin{verbatim}
+%				\begin{System}[label]
+%				    ... = ...   [& ...] \\
+%				    ... = ... +         \\*
+%				      + ...     [& ...] \\
+%				    ... = ...   [& ...]
+%				\end{System}
+%			\end{verbatim}
+%
+%		A *-form which does not generate any number is also provided.
+%			\begin{verbatim}
+%				\begin{System*}[disregarded-label]
+%				    ... = ...   [& ...] \\
+%				    ... = ... +         \\*
+%				      + ...     [& ...] \\
+%				    ... = ...   [& ...]
+%				\end{System*}
+%			\end{verbatim}
+%
+%	\subsection{The \texttt{EqSystem} environment}
+%		The ``|EqSystem|" environment is used for grouping a set of
+%		equations together inside a left brace, each with its own
+%		equation number.
+%
+%		\noindent
+%		Again there is an optional argument to indicate a label and
+%		each equation is separated by a ``|\\|" or ``|\\*|" command.
+%
+%		\noindent
+%		The rows may optionally contain one ``|&|", which is
+%		usually	used when some text should be added to the equation.
+%			\begin{verbatim}
+%				\begin{EqSystem}[label]
+%				    ... = ...   [& ...] \\    % (1.1)
+%				    ... = ... +         \\*   % (1.2)
+%				      + ...     [& ...] \\    % (1.3)
+%				    ... = ...   [& ...]       % (1.4)
+%				\end{EqSystem}
+%			\end{verbatim}
+%
+%		A *-form is also provided: it differs in that each equation
+%		is numbered with the same number but with a lowercase letter
+%		added, i.e. like (1.1a), (1.1b), etc. instead of (1.1),
+%		(1.2) and so on.
+%			\begin{verbatim}
+%				\begin{EqSystem*}[label]
+%				    ... = ...   [& ...] \\   % (1.5a)
+%				    ... = ... +         \\*  % (1.5b)
+%				      + ...     [& ...] \\   % (1.5c)
+%				    ... = ...   [& ...]      % (1.5d)
+%				\end{EqSystem*}
+%			\end{verbatim}
+%		In both cases, if the optional argument is present, each
+%		equation can be referenced by |\ref{<label>:a}|,
+%		|\ref{<label>:b}|, \dots, where |<label>|, stands for
+%		the string used as optional argument.
+%		In the case of the *-form, a reference of the kind
+%		|\ref{<label>}| will print the equation number without
+%		any letter, thus referring to the system as a whole,
+%		whereas such a reference is meaningless (and indeed does
+%		not exists) when dealing with the non *-form.
+%
+%
+% \section{Math-mode commands}
+%	In addition to the previously mentioned environments, the
+%	\texttt{\FileName} package defines also some of math-mode
+%	commands which considerably simplify the use of adjustable-size
+%	parentheses.
+%
+%	\noindent
+%	The ``|\(|", ``|\[|", ``|\{|", ``|\)|", ``|\]|"
+%	and ``|\}|" generates the corresponding parenthesis but
+%	with a ``|\left|" or ``|\right|" declaration
+%	(respectively) added, so they must come in matched pairs or
+%	coupled with a ``|\left.|" or ``|\rigtht.|" or another
+%	adjustable-size delimiter.

+%
+%    The ``|\ProcessOptions*|" command was used here instead of

+%
+% \begin{macro}{\StartMath@Err}
+%    The ``|\StartMath@Err|" prints an error message if used in math-mode
+%    (saying that you can't use the command passed to it as an argument in
+%    math-mode); otherwise it just entres math-mode through a |$$|.
+%    It is used by the *-form of the math-environments to prevent
+%    their use in math-mode.
+%    \begin{macrocode}
+%%
+\newcommand*\StartMath@Err[1]{%
+\ifmmode\PackageError{mathenv}{%
+You can't use environment "#1" in math mode}{%
+You probably used "\string\end{#1}" without a previous "\string\begin{#1}".}%
+\else$$\fi%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{environment}{Equation}
+%    The definition of the original ``|equation|" environment is first saved
+%    in the ``|\@StandardEquation|" command.
+%    Then the ``|\@LabelledEquation|" command is defined as an |equation|
+%    with a label.
+%    The |Equation| command simply calls ``|\@LabelledEquation|" or
+%    ``|\@StandardEquation|", depending on the presence or absence of the
+%    optional argument (indicated by the square bracket).
+%    \begin{macrocode}
+%%
+\AtBeginDocument{%
+\let\@StandardEquation=\equation
+}
+\def\@LabelledEquation[#1]{\@StandardEquation\label{#1}}
+\newenvironment{Equation}{%
+\@ifnextchar[{\@LabelledEquation}{\@StandardEquation}%
+}{%
+\endequation%
+}
+%    \end{macrocode}
+%
+%    If the ``|RedefEquation|" option is in effect, |equation| is defined
+%    to be the same as |Equation|.
+%    The actual definition of the |equation| environment is deferred at the
+%    ``|\begin{document}|" in order to minimize the possibility of
+%    conflicts with other packages.
+%    \begin{macrocode}
+\if@Redefine@Equation@
+  \AtBeginDocument{\let\equation=\Equation}
+\fi
+%    \end{macrocode}
+% \end{environment}
+%
+% \begin{environment}{equation*}
+%    The command ``|\Equation@Star|" simply enters math-mode (via the
+%    ``|\StartMath@Err|" command).
+%    The definition of ``|equation*|" is deferred at the
+%    ``|\begin{document}|" so that this definition takes precedence over
+%    the analogue one from the ``|amsmath|" package, if both are included.
+%    The command ``|\global\@ignoretrue|" in the definition of
+%    ``|\end{equation*}|" prevents spurious spaces at the beginning of next
+%    line.
+%    \begin{macrocode}

+% \end{environment}
+%
+% \begin{macro}{\ARRAY@CR}
+%    The original definition of ``|\@arraycr|" is saved in the command
+%    ``|\@ArrayCR|".
+%    Then ``|\ARRAY@CR|" is defined to do the same job of ``|\@arraycr|"
+%    and add a ``|\displaystyle|" declation at the beginning of next row.
+%    \begin{macrocode}

+%    command.
+%    In the *-form it also adds a space equal to ``|\MultiLineStarIndent|".

+%    It checks the |\catcode| of \& and redefines ``|\ML@EveryRow|"
+%    accordingly: if \& is a tab marker (|\catcode|=4), an ampersand has
+%    occurred in the first row, so that each row must begin itself with
+%    an ampersand; otherwise (i.e. if the |\catcode| of \& is \emph{active})

+%    It also changes the meaning of ``|\\|" to ``|\@MultiLineCR|", sets
+%    ``|\ML@EveryRow|" to its default value ``|\@MultiLINEcr|" and then
+%    starts an ``|array|" environment (we already are in math-mode
+%    here) with one only column which is left aligned.
+%    Finally, if there is an optional argument it is used as a ``|\label|"
+%    or ignored, depending on the current meaning of ``|\@LABEL|" (which
+%    is the same as ``|\label|" in the standard form and does nothing in

+% \begin{environment}{System}
+%    The ``|\@System@Def|" command is the kernel of the ``|System|" and
+%    ``|System*|" environments.
+%    It redefines ``|\@arraycr|" so that ``|\\|" not only ends the
+%    line but also adds a ``|\displaystyle|" declaration.
+%    Then it draws an adjustable-size left brace, which will be as big as
+%    the system requires.
+%    Finally, a two-column array environment with a ``|\qquad|" space
+%    between the columns is started and a ``|\displaystyle|" declaration
+%    is added to the first row.

+%    The ``|\end{System}|" command closes the array, puts an invisible
+%    delimiter (``|\right.|") which pairs with the left brace of the
+%    ``|\@System@Def|" command, restores ``|\@arraycr|" to its original

+% \section{Introduction}
+%       This package simplifies the use of double-quotes.
+%
+% \section{Double quotes}
+%
+%	With this package, the character `` |"| '' generates the correct
+%	double-quote, i.e. the sequence $<<$| " text " |$>>$
+%	generates $<<$ `` |text| '' $>>$, so that this character
+%	can be used both for opening and closing the double-quotes
+%	(provided that it is \emph{always} used).

+\ProvidesPackage{\FileName}[\filedate\space v\fileversion\space\filedescr]
+%    \end{macrocode}
+%
+%	\begin{macro}{Quotes}
+%	The command ``|\@VIRGOLETTE|" is defined to print an open or close
+%	double-quotes alternatively, so that they are always right.
+%	Moreover, the double-quotes are always printed in upright-shape,
+%	since they looks better.
+%
+%    \begin{macrocode}

+  \textup{''}%
+\else%
+  \@virgolettetrue%
+  \textup{``}%
+\fi%
+}
+%    \end{macrocode}
+%	Then the character `` |"| " is associated to the command
+%	``|\@VIRGOLETTE|" just defined, so that you just have to type
+%	this character in order to get the right double-quotes.
+%	This trick has been adapted from the |doc| package, but
+%	perhaps it may be done in a better way.

+%	Documentation for the package \texttt{\FileName}.
+% \end{abstract}
+%
+% \section{Introduction}
+%	This package provides some commands which are useful when dealing
+%	with Sobolev spaces and their relatives.
+%
+%	In particular some commands are redefined, so care should be
+%	taken, expecially when including this package in an already
+%	existent \LaTeX{} file.
+%
+%	\noindent
+%	The redefined commands are |\H| and |\L|.
+%	The effect of ``|\H|" (which is a type of accent) can now be
+%	achieved by the command ``|\HAccent|", whilst the job of ``|\L|"
+%	(i.e. print an ``L" with a superimposed bar) is now done by the
+%	command ``|\Lbar|".
+%
+% \section{The options}
+%	Two options are available at the moment: \texttt{DivInBrackets}
+%	and \texttt{DivAsExponent}.
+%	They only affect the output of the ``|\Hdiv|" command.
+%
+%	\noindent
+%	The firt options (\texttt{DivInBrackets}, which is the default)
+%	makes |\Hdiv| behave like ``|H(div;|\dots|)|", while the second
+%	one (\texttt{DivAsExponent}) makes |\Hdiv| expand to
+%	``|H^{div}(|\dots|)|".
+%
+% \section{The commands}
+%	Most of the subsequent space-generating commands have mandatory
+%	arguments to indicate the type of the space.
+%	Often this argument consists of a single digit: in this case it
+%	is \emph{not} necessary to enclose it in brackets, since in \LaTeX{}
+%	the names of commands consists of letters only, and so a digit
+%	following it is certainly an argument.
+%	This saves a lot of typing and is the only reason that makes these
+%	commans useful (if you always had to type the brackets, then it
+%	would have been simpler to type the expansion of the command than
+%	the command itself !).
+%	In other words, you can think as if several commands exist (like
+%	|\H|, |\H1|, |\H10|, etc.), the ones with the digit beeing a sort of
+%	abbreviation for the general one.
+%
+%	\subsection{The \texttt{H} command}
+%		The |\H| command is used to generate the symbol of sobolev
+%		spaces.
+%		It takes a mandatory argument, which is used as a
+%		superscript, and an optional argument, which is used as a
+%		subscript.
+%
+%		\noindent
+%		As explained above, if the mandatory argument is a digit,
+%		it need not be enclosed in brackets.
+%		Moreover, if the optional argument is the digit ``0", it
+%		can be typed without the square brackets.
+%
+%		\noindent
+%		Here are some examples (whith the |\DefaultSet| set to its
+%		default value |\Omega|):
+%
+%		\begin{tabular}{lll}
+%			|\H2|		& $\Longrightarrow$ & $H^2(\Omega)$	       \\
+%			|\H10|		& $\Longrightarrow$ & $H^1_0(\Omega)$	       \\
+%			|\H1[\Gamma_D]|	& $\Longrightarrow$ & $H^1_{\Gamma_D}(\Omega)$ \\
+%			|\H{-1/2}|	& $\Longrightarrow$ & $H^{-1/2}(\Omega)$
+%		\end{tabular}
+%
+%	\subsection{The \texttt{Hdiv} command}
+%		The |\Hdiv| command is used to generate the sobolev space
+%		called ``H div".
+%		It takes only an optional argument, which is used as a
+%		subscript and which need not to be surrounded by the square
+%		brackets if it is the digit ``0".
+%
+%		\noindent
+%		If the (default) option \texttt{DivInBrackets} is in effect,
+%		it differs from the command |\H| in that the word ``div" is
+%		printed (in roman type) inside brackets, before the set.
+%		If, instead, the option \texttt{DivAsExponent} is active,
+%		then it is simply an abbreviation for |\H{\mathrm{div}}|.
+%
+%		\noindent
+%		Here are some examples:\\
+%		\hfill \begin{tabular}{llcc}
+%					   &		       & |DivInBrackets|		     & |DivAsExponent|	\\
+%			|\Hdiv|		   & $\Longrightarrow$ & $H(\mathrm{div};\Omega)$	     & $H^{\mathrm{div}}(\Omega)$	\\
+%			|\Hdiv0|	   & $\Longrightarrow$ & $H_0(\mathrm{div};\Omega)$	     & $H^{\mathrm{div}}_0(\Omega)$	\\
+%			|\Hdiv[\Gamma_D]|  & $\Longrightarrow$ & $H_{\Gamma_D}(\mathrm{div};\Omega)$ & $H^{\mathrm{div}}_{\Gamma_D}(\Omega)$
+%		\end{tabular} \hfill
+%
+%	\subsection{The \texttt{L} command}
+%		The |\L| command is used to generate the symbol of
+%		Lebesgue-measurable functions.
+%		It has one argument which is the exponent of the L-space.
+%		Again, if this argument is a digit (or a single symbol,
+%		like ``|\infty|'') the surrounding braces are optional.
+%		Like for the |\H| command, the output of |\DefaultSet| is
+%		appended.
+%
+%		\noindent
+%		Here are some examples: \hspace{2cm}
+%		\begin{tabular}{lll}
+%			|\L2|		& $\Longrightarrow$ & $L^2(\Omega)$	       \\
+%			|\L{10}|	& $\Longrightarrow$ & $L^{10}(\Omega)$	       \\
+%			|\L\infty|	& $\Longrightarrow$ & $L^\infty(\Omega)$
+%		\end{tabular}
+%
+%	\subsection{The \texttt{W} command}
+%		The |\W| command is completly analogous, except that it
+%		prints a ``W'' insted af an ``L'' and that it has two
+%		argument, both printed as a supercript, separated by a comma.
+%		It is used for the generalized Sobolev spaces.
+%
+%		\noindent
+%		Here is an example of how it is used: \hspace{1cm}
+%		\begin{tabular}{lll}
+%			|\W{k}{p}|	& $\Longrightarrow$ & $W^{k,p}(\Omega)$ \\
+%			|\W1\infty|	& $\Longrightarrow$ & $W^{1,\infty}(\Omega)$
+%		\end{tabular}
+%
+%	\subsection{The \texttt{D} command}
+%		The |\D| command is used in the theory of distributions:
+%		it prints the space of distributions over the |\DefaultSet|
+%		if followed by a prime symbol, or its dual space, otherwise.
+%		\hfill \begin{tabular}{lll}
+%			|\D|	& $\Longrightarrow$ & $\mathcal{D}(\Omega)$ \\
+%			|\D'|	& $\Longrightarrow$ & $\mathcal{D}'(\Omega)$
+%		\end{tabular} \hfill
+%
+%	\subsection{The \texttt{Norm} command}
+%		The |\Norm| command has a mandatory and an optional argument;
+%		it generates the norm of the mandatory argument, with the
+%		optional argument, if present, as a whole subscript, to
+%		denote the space within which the norm is taken.
+%
+%		\noindent
+%		Some examples: \hspace{3cm}
+%		\begin{tabular}{lll}
+%			|\Norm{f(x)}|	& $\Longrightarrow$ & $\left\|f(x)\right\|$ \\
+%			|\Norm{g}[L^2]|	& $\Longrightarrow$ & $\left\|g\right\|_{L^2}$
+%		\end{tabular}
+%
+%	\subsection{The \texttt{SemiNorm} command}
+%		The |\SemiNorm| command is completly analoguos, but
+%		generates the semi-norm instead of the norm.
+%
+%		\noindent
+%		Some examples: \hspace{2cm}
+%		\DeleteShortVerb{\|}
+%		\MakeShortVerb{\!}
+%		\begin{tabular}{lll}
+%			!\SemiNorm{f(x)}!	& $\Longrightarrow$ & $\left|f(x)\right|$ \\
+%			!\SemiNorm{g}[H^1]!	& $\Longrightarrow$ & $\left|g\right|_{H^1}$
+%		\end{tabular}
+%		\DeleteShortVerb{\!}
+%		\MakeShortVerb{\|}
+%
+%	\subsection{The \texttt{Scalar} command}
+%		The |\Scalar| command has two arguments; a third optional
+%		argument (which is used as a whole subscript) may follow
+%		inside square brackets.
+%		The output consists of the two arguments separated by a
+%		comma and enclosed in a pair of adjustable-size brackets,
+%		with the optional argument placed as a subscript (to denote
+%		the space inside which the scalr product is taken).
+%
+%		\noindent
+%		Some examples:
+%		\begin{tabular}{lll}
+%			|\Scalar{f}{g}|	     &$\Longrightarrow$& $\left(f,g\right)$ \\
+%			|\Scalar{u}{v}[L^2]| &$\Longrightarrow$& $\left(u,v\right)_{L^2}$\\
+%		\end{tabular}
+%
+%	\subsection{The \texttt{Crochet} command}
+%		The |\Crochet| command has two arguments; a third optional
+%		argument (which is used as a whole subscript) may follow
+%		inside square brackets.
+%		The output consists of the two arguments separated by a
+%		comma and enclosed in a pair of adjustable-size
+%		angular-parenthesys, with the optional argument placed as
+%		a subscript (to denote the space inside which the duality
+%		is taken).
+%
+%		\noindent
+%		Some examples:
+%		\begin{tabular}{lll}
+%			|\Crochet{f}{g}|    &$\Longrightarrow$& $\left\langle f,g\right\rangle$ \\
+%			|\Crochet{u}{v}[D]| &$\Longrightarrow$& $\left\langle u,v\right\rangle_D$\\

+%	This command does nothing, but strips the character ``0'' (which

+% \begin{macro}{\H}
+%	The commands ``|\@HSobolev|" and``|\HSobolev@quadra|" prints
+%	an ``H" in math-mode (via the |\ensuremath| command) with the
+%	argument as a superscript, and, respectively, without subscripts
+%	and wiht the second argument as a subscript.
+%	Then they call |\@DefaultSet| in order to print the name of a set
+%	inside brackets, or nothing depending on which of the commands
+%	|\DefaultSet| and |\NoDefaultSet| has previously been invoked.

+%    \end{macrocode}
+%	The original command ``|\H|" (used to make a type of accent) is
+%	saved in |\HAccent|; then |\H| is redefined so that it calls one
+%	of the previous two commands, depending on which character
+%	follows the command name.
+%	If this character is a ``0", then it also invokes the command
+%	|\DoNothing@zero|, in order to strip that zero from the input.
+%	All this is deferred at the ``|\begin{document}|" in order to

+% \end{macro}
+%
+% \begin{macro}{\Hdiv}
+%	The command |\@Hdiv@quadra| is used if the command |\Hdiv| is
+%	followed by a square bracket: it simply types ``H" (in math mode)
+%	with a subscript.
+%	It also prints ``div" (in roman) as an exponent and calls
+%	|\@DefaultSet| (with the ``DivAsExponent" option) or calls
+%	|\@DefaultSet@Div| (with the ``DivInBraces" option).

+%	The ``|\Hdiv|" command is defined so that it calls the previous command,
+%	or typesets the output itself, similarly to the |\H| command above.

+% \begin{macro}{\L}
+%	First the old command |\L| (which prints an ``L" whith a bar
+%	superimposed) is saved in |\Lbar|.
+%	Then |\L| is redefined to print an ``L" in math-mode with its
+%	argument as a superscript, followed by the output of |\@DefaultSet|.

+% \begin{macro}{\W}
+%	The command |\W| is defined to print a ``W" in math-mode with its
+%	two arguments as a superscript (separated by a comma) and followed
+%	by the output of |\@DefaultSet|.
+%	It is deferred at the ``|\begin{document}|" in order to
+%	avoid conflicts with other packages.

+% \begin{macro}{\D}
+%	The command |\D| is defined to print a calligraphic ``D" in
+%	math-mode, followed by the output of |\@DefaultSet|.
+%	In order to allow for the proper treatment of the \emph{prime}
+%	symbol which can follow the command, the command |\InsiemeD@Primo|
+%	is defined: it is authomatically invoked by the command |\D| when
+%	followed by a prime. It differs only in that a prime is output
+%	\emph{before} invoking |\@DefaultSet|.
+%	This is deferred at the ``|\begin{document}|" in order to
+%	avoid conflicts with other packages.

+% \begin{macro}{\Scalar}
+%	The command |\Scalar| requires two arguments; a third optional
+%	argument (which is used as a whole subscript) may follow inside
+%	square brackets.
+%	The output consists of the two arguments separated by a comma and
+%	enclosed in a pair of adjustable-size brackets, with the optional
+%	argument placed as a subscript.
