+
+
+This file describes the LaTeX packages developed and mantained
+by F. Bosisio at the "Politecnico di Milano", Italy.
+See file "index.html" for a more detailed description of each package.
+
+For information on the whole LaTeX packages visit the CTAN archive
+(http://www.ctan.org) or search the CTAN Catalogue online
+(http://www.ctan.org/Catalogue).
+
+At now the available packages are:
+ * envmath:
+ - Extended and more powerful math-environments
+ - The new math environments are used to make multi-line formulas and
+ systems of equations, both numbered or unnumbered.
+
+ * mathenv:
+ - Old name for the "envmath" package
+ - Package "mathenv" has been renamed to "envmath", in order to avoid
+ conflicts with another package with the same name: if you were using
+ the "old" "mathenv" package, you need to change your LaTeX files in
+ order to include the new one.
+
+ * mathcmd:
+ - Extended math-mode commands
+ - New commands include derivatives, vectors operators, arrow-limits,
+ integrals and sums.
+
+ * sobolev:
+ - Commands to deal with Sobolev and Hilbert spaces
+ - The new commands include norm, semi-norm, scalar products, crochet
+ symbols, besides the various Sobolev spaces.
+
+ * graphfig:
+ - Simple and powerful way of using graphics files inside figures
+ - It provides a new "Figure" environment and a "\graphfile" command:
+ the combined use of these authomatically produce a correct centering
+ of the graph(s) with respect to the page.
+ Moreover, subfigures can be handled in the same way and hard-to-discover
+ errors (such as a "\label" preceding a "\caption") are eliminated.
+
+ * dblfont:
+ - An easy way to define blackboard-bold letters
+
+ * accenti:
+ - This package is obsolete and its only aim is to simplify the usage
+ of accents in the Italian language.
+ - The declaration "\usepackage[latin1]{inputenc}" is a better alternative,
+ as it directly allows the use of the accented characters in the document,
+ which is extremly useful with an italian keyboard.
+
+ * quotes:
+ - Use double-quote character for both opening and closing quotes.
+
+ * evenpage:
+ - Ensure that the number of pages generated by "LaTeX" is an even number.
+
+Besides the packages themselves, also the "makedoc" utility is available:
+it is a UNIX shell-script that takes a ".dtx" file and extracts both the
+".sty" file and the documentation (which is automatically compiled with LaTeX).
+The script only works for ".dtx" files that are structured like my packages,
+i.e. they must directly produce the style-file and a documentation-driver
+(".drv") when simply run through LaTeX.
+
+If you have any suggestions, find any bugs or make any improvment on any of
+my packages, please let me know about it by sending an E-mail at the following
+address: fbosisio@bigfoot.com

+%
+% \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|'',\\
+% whose 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{Obsolete package}
+%
+% This package is \emph{obsolete}, as it has been superseeded by
+% the standard ``|inputenc|'' package: indeed, the declaration\\
+% \mbox{}\qquad |\usepackage[latin1]{inputenc}|\\
+% directly allows the use of the characters ``\`a'', ``\`e'',
+% ``\`\i'', ``\`o'', ``\`u'' and ``\'e'' in the document, which
+% is extremly useful with an italian keyboard.
+%
+% \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
+% characters ``\`a'', ``\`e'', ``\`\i'', ``\`o'', ``\`u'' and ``\'e''
+% as accents-making commands.
+% The second option 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|''.

+%
+% The original commands ``|\a|'', ``|\i|'', ``|\o|'' and ``|\u|'' are
+% saved before being redefined.
+% The combined use of an intermediate internal command and of
+% ``|\DeclareRobustCommand*|'', allow for all the commands of the
+% package to be robust (even the saved original ones).

+%
+% 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''

+% The definitions are deferred at the ``|\begin{document}|''
+% in order to avoid conflicts with other packages.

+% \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 commands ``|\X|'' and ``|\XX|'' which
+% both generate the letter |X| in |DblFont|.
+% If a command named ``|\X|'' or ``|\XX|'' already exists in \LaTeX{},
+% its 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).

+%
+% The font ``|\DblFont|'' is loaded, if not already done.
+% \begin{macrocode}
+%%
+\newfont{\DblFont}{msbm10 scaled \magstep1}
+% \end{macrocode}
+%
+% The ``|\DeclareDblFontSymbol|'' has one argument which is used
+% both as the command name to define and as the output it should
+% generate (in |\DblFont|).
+% The ``|\csname #1 \endcsname|'' sequence adds a backslash in front
+% of the argument, to get the command name.
+% \begin{macrocode}
+%%
+\newcommand*\DeclareDblFontSymbol[1]{%
+\expandafter\newcommand*\csname #1\endcsname{\ensuremath{\mathbb{#1}}}%
+}
+% \end{macrocode}
+% The ``|\dECL@REdBLfONTsYMBOL|'' has one argument which is used
+% both as the command name to define (doubled) and as the output
+% it should generate (in |\DblFont|).
+% The ``|\csname #1#1 \endcsname|'' sequence adds a backslash in front
+% of the argument and doubles it, to get the command name.
+% \begin{macrocode}
+\newcommand*\dECL@REdBLfONTsYMBOL[1]{%
+\expandafter\newcommand*\csname #1#1\endcsname{\ensuremath{\mathbb{#1}}}%
+}
+% \end{macrocode}
+%
+% The command ``|\BackUpL@texCmd{<X>}|'' saves the command ``|\<X>|'' in
+% the macro ``|\BackDouble<X>|'' and then undefines ``|\<X>|'', so that a
+% ``|\newcommand*\<X>{..}|'' can be used to redefine it.
+% \begin{macrocode}
+%%
+\newcommand*\BackUpL@texCmd[1]{%
+\expandafter\let\csname BackDouble#1\endcsname=\csname #1\endcsname%
+\expandafter\let\csname #1\endcsname\undefined%
+\typeout{*** Command name ``#1'' has been replaced by ``BackDouble#1''! ***}%
+}
+% \end{macrocode}
+%
+% An option exists for each uppercase letter: it declares the
+% command ``|\X|'' which generates the letter |X| in |DblFont|,
+% where |X| denotes the letter under consideration.
+% If a command named ``|\X|'' already exists in \LaTeX{}, its definition
+% is saved in ``|\BackDoubleX|'', before being redefined.

+%
+% \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{Backward compatibility}
+% The package has been renamed from ``|mathenv|'' to ``|envmath|'',
+% in order to avoid conflicts with another package with the same name:
+% if you were using the ``old'' package, you need to change your \LaTeX{}
+% files in order to include the new ones.\\
+% Alternatively, you can also rename the package to give it the ``old''
+% name (you need to change also the ``|\def\FileName{...}|'' line inside
+% the ``|sty|''-file), but you must take care not to have another package
+% with the same name installed on your system.
+%
+% \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.

+
+<h2>
+<a name="SECTION01">Introduction</a>
+</h2>
+
+<p>
+This package provides some useful math-commands and enviroments, which
+are simpler to use and prettier then their standard LaTeX counterpart.
+</p>
+
+<p>
+In particular some commands are redefined
+(see <a href="#SECTION02">next section</a> if you don't want them to be
+redefined), so care should be taken, expecially when including this package
+in an already existent LaTeX file.
+
+<p>
+The <a href="#SECTION04">redefined commands</a> are:<br />
+<tt>\(</tt>, <tt>\)</tt>,
+<tt>\[</tt>, <tt>\]</tt>,
+<tt>\{</tt> and <tt>\}</tt>.<br />
+The effect of ``<tt>\(</tt> ...<tt>\)</tt>'' can still be achieved by
+the LaTeX equivalent commands ``<tt>\begin{math} ... \end{math}</tt>''
+or ``<tt>$...$</tt>''.
+</p>
+
+<p>
+Similarly, the effect of ``<tt>\[...\]</tt>'' can be achieved by the
+LaTeX equivalent commands
+``<tt>\begin{displaymath}...\end{displaymath}</tt>'' or
+``<tt>$$...$$</tt>''.
+</p>
+
+<p>
+The ``<tt>\{</tt>'' and ``<tt>\}</tt>'' commands are the more
+error-prone, since one may try to use ``<tt>\left\{</tt>'', which now
+is incorrect, because the ``<tt>\{</tt>'' command already contains a
+``<tt>\left</tt>'' declaration.
+In the rare occasions where a brace of normal size is needed, one can use
+the LaTeX commands ``<tt>\lbrace</tt>'' and ``<tt>\rbrace</tt>''.
+</p>
+
+<p>
+Also the <a href="#SECTION03a">``<tt>equation</tt>'' environment</a> 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.
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h2>
+<a name="SECTION02">The options</a>
+</h2>
+
+<p>
+At now, five options are available with the <tt>envmath</tt> package.
+</p>
+
+<p>
+The ``<tt>RedefEquation</tt>''/``<tt>StdEquation</tt>'' and
+``<tt>RedefBrackets</tt>''/``<tt>StdBrackets</tt>'' options control
+whether the ``<tt>equation</tt>'' environment and the brace commands
+``<tt>\(</tt>'', ``<tt>\)</tt>'', ``<tt>\[</tt>'',
+``<tt>\]</tt>'', ``<tt>\{</tt>'' and ``<tt>\}</tt>'' should
+be redefined or retain their original LaTeX meaning.
+</p>
+
+<p>
+More precisely, ``<tt>RedefEquation</tt>'' (default) redefines the
+``equation'' environment to have an optional argument (used as a label),
+while ``<tt>StdEquation</tt>'' leaves it unchanged.
+In the first case, the ``equation'' environment will be equivalent to the
+<a href="#SECTION03a">``Equation'' environment</a> (capitalized!) described
+below, whereas in the second case they will be different.
+</p>
+
+<p>
+Similarly, the ``<tt>RedefBrackets</tt>'' option (default) makes the
+<a href="#SECTION04"> bracket commands</a> to be redefined, whilst
+``<tt>StdBrackets</tt>'' leave them their original meaning.
+</p>
+
+<p>
+Also a ``<tt>Standard</tt>'' option exists, which amounts to specify both
+the ``<tt>StdEquation</tt>'' and ``<tt>StdBrackets</tt>'' options, thus making
+the package fully standard, which may be useful when sending your
+LaTeX files to someone else.
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h2>
+<a name="SECTION03">Math-mode environments</a>
+</h2>
+
+<p>
+This package provides some math-mode environments, each with a ``*-form''
+which does not generates numbers (or produce sub-numbering).
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h3>
+<a name="SECTION03a">The <tt>Equation</tt> environment</a>
+</h3>
+
+<p>
+The ``<tt>Equation</tt>'' environment has an optional argument which is used
+as a label to reference it.
+<pre>
+ \begin{Equation}[&lt;label&gt;]
+ ...
+ \end{Equation}
+</pre>
+</p>
+
+<p>
+If the ``<tt>RedefEquation</tt>'' option is in effect (default), then
+the ``<tt>equation</tt>'' environment is redefined to have the same optional
+argument as ``<tt>Equation</tt>''.
+</p>
+
+<p>
+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).
+</p>
+
+<p>
+The *-form has an optional argument like the non-* form, which is
+disregarded by the environment and is added only for simmetry reasons.
+<pre>
+ \begin{equation*}[&lt;disregarded-label&gt;]
+ ...
+ \end{equation*}
+</pre>
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h3>
+<a name="SECTION03b">The <tt>MultiLine</tt> equation environment</a>
+</h3>
+
+<p>
+The ``<tt>MultiLine</tt>'' environment is intended for formulas that don't
+fit on a single line, and so must be broken across lines.
+</p>
+
+<p>
+As for the <a href="#SECTION03a"><tt>Equation</tt> environment</a> above,
+it has an optional argument which is used as a label.
+</p>
+
+<p>
+All the lines but the first are automatically indented by the lenght
+``<tt>\MultiLineIndent</tt>'', which is rougthly what one expects, but
+can be changed at any time by the user with
+``<tt>\setlenght\MultiLineIndent{...}</tt>''.
+You can also control the alignment of the continuation rows by placing an
+optional <tt>&amp;</tt> in the first row: is such a case all the others line
+will <em>not</em> be indented by ``<tt>\MultiLineIndent</tt>'' but wil behave
+<em>as if</em> there were an ampersand in front of them (i.e. they will be
+left-aligned at the right of the &amp; in the first row).
+</p>
+
+<p>
+Each line but the last must end with a ``<tt>\\</tt>'' 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 ``<tt>\\*</tt>''
+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 this space defaults to 1em and can be changed by the user
+with ``<tt>\setlenght\MultiLineStarIndent{...}</tt>''.
+</p>
+
+<p>
+<pre>
+ \begin{MultiLine}[&lt;label&gt;]
+ ... [&amp;]= ... = \\
+ = ... + \\*
+ + ... = \\
+ = ...
+ \end{MultiLine}
+</pre>
+</p>
+
+<p>
+Also this environment has a *-form which differs only in that it does not
+generate an equation number.
+<pre>
+ \begin{MultiLine*}[&lt;disregarded-label&gt;]
+ ... [&amp;]= ... = \\
+ = ... + \\*
+ + ... = \\
+ = ...
+ \end{MultiLine*}
+</pre>
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h3>
+<a name="SECTION03c">The <tt>System</tt> environment</a>
+</h3>
+
+<p>
+The ``<tt>System</tt>'' environment is used for grouping a set of equations
+together inside a left brace, with one only equation number.
+</p>
+
+<p>
+Again there is an optional argument to indicate a label and each equation
+is separated by a ``<tt>\\</tt>'' or ``<tt>\\*</tt>'' command,
+as for the <a href="#SECTION03b">``<tt>MultiLine</tt>'' environment</a>.
+</p>
+
+<p>
+The rows (except the ones ended with the *-form ``<tt>\\*</tt>'')
+may optionally contain one ``<tt>&amp;</tt>'', which is usually used when
+some text should be added to the equation.
+<pre>
+ \begin{System}[&lt;label&gt;]
+ ... = ... [&amp; ...] \\
+ ... = ... + \\*
+ + ... [&amp; ...] \\
+ ... = ... [&amp; ...]
+ \end{System}
+</pre>
+</p>
+
+<p>
+A *-form which does not generate any number is also provided.
+<pre>
+ \begin{System*}[&lt;disregarded-label&gt;]
+ ... = ... [&amp; ...] \\
+ ... = ... + \\*
+ + ... [&amp; ...] \\
+ ... = ... [&amp; ...]
+ \end{System*}
+</pre>
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h3>
+<a name="SECTION03d">The <tt>EqSystem</tt> environment</a>
+</h3>
+
+<p>
+The ``<tt>EqSystem</tt>'' environment is used for grouping a set of equations
+together inside a left brace, each with its own equation number.
+</p>
+
+<p>
+Again there is an optional argument to indicate a label and each equation is
+separated by a ``<tt>\\</tt>'' or ``<tt>\\*</tt>'' command.
+</p>
+
+<p>
+The rows may optionally contain one ``<tt>&amp;</tt>'', which is usually used
+when some text should be added to the equation.
+<pre>
+ \begin{EqSystem}[&lt;label&gt;]
+ ... = ... [&amp; ...] \\ % (1.1)
+ ... = ... + \\* %
+ + ... [&amp; ...] \\ % (1.2)
+ ... = ... [&amp; ...] % (1.3)
+ \end{EqSystem}
+</pre>
+</p>
+
+<p>
+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.
+<pre>
+ \begin{EqSystem*}[&lt;label&gt;]
+ ... = ... [&amp; ...] \\ % (1.5a)
+ ... = ... + \\* %
+ + ... [&amp; ...] \\ % (1.5b)
+ ... = ... [&amp; ...] % (1.5c)
+ \end{EqSystem*}
+</pre>
+In both cases, if the optional argument is present, each equation can be
+referenced by <tt>\ref{&lt;label&gt;:a}</tt>,
+<tt>\ref{&lt;label&gt;:b}</tt>, ..., where <tt>&lt;label&gt;</tt>,
+stands for the string used as optional argument.
+In the case of the *-form, a reference of the kind
+<tt>\ref{&lt;label&gt;}</tt> 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.
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h2>
+<a name="SECTION04">Math-mode commands</a>
+</h2>
+
+<p>
+In addition to the previously mentioned environments, the <tt>envmath</tt>
+package defines also some of math-mode commands which considerably simplify
+the use of adjustable-size parentheses.
+</p>
+
+<p>
+The ``<tt>\(</tt>'', ``<tt>\[</tt>'', ``<tt>\{</tt>'',
+``<tt>\)</tt>'', ``<tt>\]</tt>'' and ``<tt>\}</tt>'' generates
+the corresponding parenthesis but with a ``<tt>\left</tt>'' or
+``<tt>\right</tt>'' declaration (respectively) added, so they must come
+in matched pairs or coupled with a ``<tt>\left.</tt>'' or
+``<tt>\rigtht.</tt>'' or another adjustable-size delimiter.
+</p>

+% The code simply checks if the current page number is odd, in

+% (the |\mbox{}| is needed, otherwise the page will be empty

+% The use of |\thispagestyle{empty}| ensures that nothing

+%
+% \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 argument 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''.

+% \section{Implementation}
+% We start defining the options and including the required packages.
+% \begin{macrocode}

+% \end{macrocode}
+%
+% These redefinitions are needed in order to obtain the right form
+% of the references (i.e. like ``Fig. 1a'' and not ``Fig. 1(a)'')
+% \begin{macrocode}
+ \def\thesubfigure{\alph{subfigure}}
+% \end{macrocode}
+%
+% We use ``|\renewcommand|'' instead of ``|\def|'' in order to realize
+% possible changes in the |subfigure| package which may eliminate the
+% inner command ``|\@thesubfigure|''.
+% \begin{macrocode}
+ \renewcommand*\@thesubfigure{{\subcaplabelfont(\thesubfigure)}\space}
+ \let\SubGR@PH=\subfigure
+\else
+% \end{macrocode}
+%
+% If the ``subfigure'' option is not present, we let the internal
+% command ``|\SubGR@PH|'' to simply execute its mandatory argument
+% \begin{macrocode}
+ \newcommand*\SubGR@PH[2][]{#2}
+\fi
+\if@AllowHfloat
+ \RequirePackage{float}[1995/03/29 v1.2c]
+ \restylefloat{figure}
+\fi
+%%
+\newif\if@FirstPicture\@FirstPicturetrue
+\let\SubFig@Label=\relax
+% \end{macrocode}
+%
+% \begin{macro}{\@Graph@Figure}
+% This is the core command which includes and scales the graphic file
+% using the commands provided by the |graphic| package.
+% \begin{macrocode}
+%%
+\newcommand*\@Graph@Figure[3]{\resizebox{#1}{#2}{\includegraphics*{#3}}}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\graphfile}
+% The command ``|\graphfile''| and its *-version simply calls one
+% of the forthcoming commands.
+% \begin{macrocode}
+\newcommand*\graphfile{\@ifnextchar*{\graphfile@star}{%
+\@ifnextchar[{\GraphFile@width}{\GraphFile@noSize}}%
+}
+\def\graphfile@star*{\@ifnextchar[{\GraphFile@heigth}{\GraphFile@noSize}}
+% \end{macrocode}
+% These commands, in turns, calls ``|\@GraphFile@Draw|'' with suitable
+% arguments (i.e. the lengths are turned into fractions of ``|\linewidth|''
+% and an exclamation mark ``|!|'' is used where the scaling factor has
+% to be the same as the other direction; furthermore the actual size
+% of the graphic image is used [throught the ``|\width|'' command] if
+% no scaling parameter is given).
+% \begin{macrocode}
+%%
+\def\GraphFile@width[#1]{%
+\@ifnextchar[{\@GraphFile@width@heigth{#1}}{\@GraphFile@widthNOheigth{#1}}%
+}
+\def\@GraphFile@width@heigth#1[#2]#3{%
+\@ifnextchar[{\@GraphFile@Draw{.#1\linewidth}{.#2\linewidth}{#3}}{%
+\@GraphFile@Draw{.#1\linewidth}{.#2\linewidth}{#3}[]}%
+}
+\def\@GraphFile@widthNOheigth#1#2{%
+\@ifnextchar[{\@GraphFile@Draw{.#1\linewidth}{!}{#2}}{%
+\@GraphFile@Draw{.#1\linewidth}{!}{#2}[]}%
+}
+\def\GraphFile@heigth[#1]#2{%
+\@ifnextchar[{\@GraphFile@Draw{!}{.#1\linewidth}{#2}}{%
+\@GraphFile@Draw{!}{.#1\linewidth}{#2}[]}%
+}
+\newcommand*\GraphFile@noSize[1]{%
+\@ifnextchar[{\@GraphFile@Draw{\expandafter\width}{!}{#1}}{%
+\@GraphFile@Draw{\expandafter\width}{!}{#1}[]}%
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@GraphFile@Draw}
+% This command has three mandatory arguments and an optional one,
+% which represent, respectively, the width, heigth, file-name and
+% sub-caption of the current picture.
+% \begin{macrocode}
+%%
+\def\@GraphFile@Draw#1#2#3[#4]{%
+\if@FirstPicture%
+% \end{macrocode}
+% If it is the first call to this command in the current |Figure|
+% environment, we simply store it in ``|\TMP@Graph|''.
+% We also set ``|@FirstPicture|'' to false for the next call.
+% \begin{macrocode}
+ \@FirstPicturefalse%
+ \def\TMP@Graph{\SubGR@PH[#4\SubFig@Label]{\@Graph@Figure{#1}{#2}{#3}}}%
+\else%
+ \ifx\TMP@Graph\undefined%
+% \end{macrocode}
+% If ``|\TMP@Graph|'' is not defined, this is the third call (or more).
+% So we invoke the ``|\SubGR@PH|'' command (which may be ``|\subfigure|''
+% or simply its second argument depending on the options) with a
+% ``|\@Graph@Figure|'' command inside and followed by an ``|\hfill|''
+% command for centering purposes.
+% \begin{macrocode}
+ \SubGR@PH[#4\SubFig@Label]{\@Graph@Figure{#1}{#2}{#3}}\hspace*{\fill}%
+ \else%
+% \end{macrocode}
+% If we arrive at this point it is the second call to ``|\graphfile|''
+% inside the current |Figure| environment: before plotting the
+% current figure (as above) we must call ``|\TMP@Graph|'' to plot
+% the first one (which was only saved).
+% We also undefine ``|\TMP@Graph|'' for the next time.
+% \begin{macrocode}
+ \hspace*{-4pt}\TMP@Graph\hspace*{\fill}%
+ \let\TMP@Graph\undefined%
+ \SubGR@PH[#4\SubFig@Label]{\@Graph@Figure{#1}{#2}{#3}}\hspace*{\fill}%
+ \fi%
+\fi%
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\FigureDefaultPlacement}
+% The ``|\FigureDefaultPlacement|'' macro is defined to set the value of
+% the ``|\Default@FigurePlacement|'' to its argument.
+% Also ``|\Default@FigurePlacement|'' is initialized to ``|htbp|''.
+% \begin{macrocode}
+%%
+\newcommand*\FigureDefaultPlacement[1]{\def\Default@FigurePlacement{#1}}
+\def\Default@FigurePlacement{htbp}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{environment}{Figure}
+% \begin{macrocode}
+%%
+\newenvironment{Figure}[2][\Default@FigurePlacement]{%
+% \end{macrocode}
+% The code for ``|\begin{Figure}|'' starts by setting ``|@FirstPicture|''
+% to true.
+% \begin{macrocode}
+\@FirstPicturetrue%
+% \end{macrocode}
+% Then we start a standard ``|figure|'' environment followed by an
+% ``|\hfill|'' command (for centering purposes).
+% \begin{macrocode}
+\figure[#1]%
+\hspace*{\fill}%
+% \end{macrocode}
+% We change the definition of ``|\\|'' so that an ``|\hfill|'' command
+% is added at the beginning of next line.
+% \begin{macrocode}
+\let\@Figure@CR=\\%
+\def\\{\par\hspace*{\fill}}%
+% \end{macrocode}
+% If there is the last optional argument, ``|\@Figure@quadra|'' is
+% invoked, otherwise ``|\MK@Figure@Caption|'' is directly defined
+% to print the specified caption.
+% \begin{macrocode}
+\@ifnextchar[{\@Figure@quadra{#2}}{\def\MK@Figure@Caption{\caption{#2}}}%
+}{%
+% \end{macrocode}
+% The code for ``|\end{Figure}|'' starts by checking that ``|\TMP@Graph|''
+% is undefined, otherwise this means that there was one only picture:
+% in such a case we have to print it out before continuing.
+% \begin{macrocode}
+\ifx\TMP@Graph\undefined\else%
+ \if@AllowSubFigure%
+ \renewcommand*\SubGR@PH[2][]{##2}%
+ \TMP@Graph\hspace*{\fill}%
+ \let\SubGR@PH=\subfigure%
+ \else%
+ \TMP@Graph\hspace*{\fill}%
+ \fi%
+ \global\let\TMP@Graph\undefined%
+\fi%
+% \end{macrocode}
+% The ``|\MK@Figure@Caption|'' prints the previously saved caption.
+% \begin{macrocode}
+\MK@Figure@Caption%
+% \end{macrocode}
+% All local commands are undefined in order to save \TeX{} memory.
+% \begin{macrocode}
+\let\Mk@Figure@Caption\undefined%
+\let\SubFig@Label=\relax%
+\let\\=\@Figure@CR%
+\let\@Figure@CR\undefined%
+% \end{macrocode}
+% The standard ``|figure|'' environment is closed.
+% \begin{macrocode}
+\endfigure%
+% \end{macrocode}
+% The command ``|\thesubfigure|'' is redefined so that it correctly
+% prints the figure number, too.
+% \begin{macrocode}
+\def\thesubfigure{\thefigure\alph{subfigure}}%
+}
+% \end{macrocode}
+% \end{environment}
+%
+% \begin{macro}{\@Figure@quadra}
+% The ``|\MK@Figure@Caption|'' is defined to print the specified
+% caption with an added label.
+% Also ``|\SubFig@Label|'' generates a label in the form ``|<label>:a|''.

+LaTeX document very simply.
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h2>
+<a name="SECTION02">Required packages</a>
+</h2>
+
+<p>
+This package uses the ``<tt>\includegraphics*</tt>'' command defined in
+the standard <tt>graphics</tt> package.
+Moreover, it uses the package <tt>subfigure</tt> when the
+<a href="#SECTION03"><tt>subfigure</tt> option</a> is specified, and the
+<tt>float</tt> package if the <a href="#SECTION03"><tt>AllowH</tt> option</a>
+is used.
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h2>
+<a name="SECTION03">The options</a>
+</h2>
+
+<p>
+At now, two options are available: ``<tt>subfigure</tt>'' and
+``<tt>AllowH</tt>''.
+</p>
+
+<p>
+The ``<tt>subfigure</tt>'' option allow the use of sub-figures inside a
+<a href="#SECTION04"><tt>Figure</tt> environment</a>, in order to place
+multiple pictures in a single LaTeX figure (cfr. the <tt>subfigure</tt>
+standard package).
+</p>
+
+<p>
+The ``<tt>AllowH</tt>'' option allow the use of the ``<tt>H</tt>'' float
+specifier for the <a href="#SECTION04"><tt>Figure</tt> environment</a>,
+in order to place the figure exaclty where the command is placed
+(cfr. the <tt>float</tt> standard package).
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h2>
+<a name="SECTION04">The <tt>Figure</tt> environment and its relatives</a>
+</h2>
+
+<p>
+The ``<tt>Figure</tt>'' environment (capitalized!) is somewhat different from
+the standard LaTeX ``<tt>figure</tt>'' environment: besides an optional
+argument used to specify the placement parameters (which now defaults to
+``<tt>[htbp]</tt>''), it has a mandatory agrument specifying the ``caption''
+and another optional argument, used as a ``label'' for cross-referencies:
+<pre>
+ \begin{Figure}[&lt;htbpH&gt;]{&lt;caption&gt;}[&lt;label&gt;]
+ ...
+ \end{Figure}
+</pre>
+</p>
+
+<p>
+The use of the ``<tt>H</tt>'' specifier (i.e. ``I want my float here!'') is
+possible only if the <a href="#SECTION03">``<tt>AllowH</tt>'' option</a> has
+been specified.
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h3>
+<a name="SECTION04a">The <tt>graphfile</tt> command</a>
+</h3>
+
+<p>
+Inside the ``<tt>Figure</tt>'' environment, are available the commands:
+<pre>
+ \graphfile[&lt;width&gt;]{&lt;file&gt;}[&lt;sub-caption&gt;]
+ \graphfile*[&lt;heigth&gt;]{&lt;file&gt;}[&lt;sub-caption&gt;]
+</pre><br />
+which are a simplified version of the ``<tt>\includegraphics*</tt>''
+command (which is automatically included by this package; see the
+<tt>graphics</tt> 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 ``<tt>\linewidth</tt>'' (e.g. ``|50|'' means
+``<tt>.50\linewidth</tt>'', i.e. half a line! ), so no unit of measure
+(as ``<tt>cm</tt>'' or ``<tt>pt</tt>'') is required.
+</p>
+
+<p>
+Moreover, since the ``*-form'' of ``<tt>\includegraphics</tt>'' is used,
+the regions outside the bounding-box of postscript files are not drawn.
+</p>
+
+<p>
+Another advantage of the combined use of the
+<a href="#SECTION04">``<tt>Figure</tt>'' environment</a> and the
+``<tt>\graphfile</tt>'' commands is that the picture is automatically
+centered horizontally, so no ``<tt>\centering</tt>'' or similar
+declartion is required.
+<pre>
+ \begin{Figure}[&lt;htbpH&gt;]{&lt;caption&gt;}[&lt;label&gt;]
+ \graphfile[&lt;width&gt;]{&lt;file&gt;}
+ \end{Figure}
+</pre>
+</p>
+
+<hr /><br />
+<!------------------------------------------------------------------------>
+
+<h3>
+<a name="SECTION04b">Sub-figures</a>
+</h3>
+
+<p>
+If you want to include more than one file in a single figure, you may
+specify <a href="#SECTION03">the ``<tt>subfigure</tt>'' option</a>, which
+includes the <tt>subfigure</tt> package and provides the authomatic
+placement of a sub-caption below each picture.
+</p>
+
+<p>
+If the ``<tt>subfigure</tt>'' option is not specified, multiple graphs are
+still allowed but no sub-caption will appear.
+<pre>
+ \graphfile[&lt;width_1&gt;]{&lt;file_1&gt;}[&lt;sub-caption_1&gt;]
+ ...
+ \graphfile[&lt;width_N&gt;]{&lt;file_N&gt;}[&lt;sub-caption_N&gt;]
+</pre><br />
+This is a combined version of ``<tt>\subfigure</tt>'' and
+``<tt>\includegraphics*</tt>'' (see the <tt>subfigure</tt> and
+<tt>graphics</tt> 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 <tt>subfigure</tt> option was not specified, in which
+case it is simply ignored).
+</p>
+
+<p>
+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 ``<tt>\graphfile[...]{...}[...]</tt>'' commands
+inside a ``<tt>Figure</tt>'' environment provides an equal spacing beetween
+the pictures and around them, without the need for any extra command.
+</p>
+
+<p>
+Finally, if a ``<tt>&lt;label&gt;</tt>'' was specified as the last optional
+argument to the <a href="#SECTION04">``<tt>Figure</tt>'' environment</a>,
+you can reference to each individual sub-figure by the labels
+``<tt>&lt;label&gt;:a</tt>'', ``<tt>&lt;label&gt;:b</tt>'', and so on, without
+the need for declaring them.
+<pre>
+ \begin{Figure}[&lt;htbpH&gt;]{&lt;caption&gt;}[&lt;label&gt;]
+ \graphfile[&lt;width_1&gt;]{&lt;file_1&gt;}[&lt;sub-caption_1&gt;]
+ \graphfile[&lt;width_2&gt;]{&lt;file_2&gt;}[&lt;sub-caption_2&gt;]
+ :
+ :
+ \end{Figure}
+</pre>

+
+<h1><a name="envmath">The "envmath" package</h1>
+
+<p>
+ This package provides some environments and commands which I found very
+ useful in math-mode.
+</p>
+
+<p>
+ The new math environments are used to make multi-line formulas and systems
+ of equations, both numbered or unnumbered.
+ Also the standard <em>equation</em> environment may be redefined so that
+ it has the same optional argument as the other ones (this optional argument
+ is simply a label for cross-referencies).
+</p>
+
+<p>
+ Also a very simple way of making adjustable-size matching braces is
+ available.
+</p>
+
+<p>
+ For more informations, see the <a href="envmath.html">on-line documentation</a>
+ or download the <a href="envmath.pdf">documentation file</a>.
+</p>
+
+<p>
+ The source file is <a href="envmath.dtx">envmath.dtx</a>, which also
+ deserves as an installation driver: simply run it through LaTeX in order
+ to get the corresponding <samp>envmath.sty</samp> file and also the
+ documentation driver <samp>envmath.drv</samp> (which you must run throught
+ LaTeX to get the documentation).
+</p>
+
+<hr />
+
+<h1><a name="mathenv">The <em>obsolete</em> "mathenv" package</h1>
+
+<p>
+ The package "<tt>mathenv</tt>" has been renamed to
+ "<tt><a href="#envmath">envmath</a></tt>", in order to avoid conflicts with
+ another package with the same name: if you were using the "old"
+ "<tt>mathenv</tt>" package, you need to change your LaTeX files in order to
+ include the new one.<br />
+ Alternatively, you can also rename the "new" package to give it the "old"
+ name (you need to change also the "<tt>\def\FileName{...}</tt>" line inside
+ the "<tt>sty</tt>"-file), but you must take care not to have another package
+ with the same name installed on your system.
+</p>
+
+<hr />
+
+<h1><a name="mathcmd">The "mathcmd" package</h1>
+
+<p>
+ This package provides some commands which I found very useful in math-mode.
+</p>
+
+<p>
+ The new commands include derivatives, vectors operators, arrow-limits,
+ integrals and sums.
+</p>
+
+<p>
+ For more informations, see the <a href="mathcmd.html">on-line documentation</a>
+ or download the <a href="mathcmd.pdf">documentation file</a>.
+</p>
+
+<p>
+ The source file is <a href="mathcmd.dtx">mathcmd.dtx</a>, which also
+ deserves as an installation driver: simply run it through LaTeX in order
+ to get the corresponding <samp>mathcmd.sty</samp> file and also the
+ documentation driver <samp>mathcmd.drv</samp> (which you must run throught
+ LaTeX to get the documentation).
+</p>
+
+<hr />
+
+<h1><a name="sobolev">The "sobolev" package</h1>
+
+<p>
+ This package provides some commands which I found very useful when
+ dealing with higher Mathematics that envolves the use of Hilbert and
+ Sobolev spaces.
+</p>
+
+<p>
+ The new commands include norm, semi-norm, scalar products, crochet symbols,
+ besides the various Sobolev spaces.
+</p>
+
+<p>
+ For more informations, see the <a href="sobolev.html">on-line documentation</a>
+ or download the <a href="sobolev.pdf">documentation file</a>.
+</p>
+
+<p>
+ The source file is <a href="sobolev.dtx">sobolev.dtx</a>, which also
+ deserves as an installation driver: simply run it through LaTeX in order
+ to get the corresponding <samp>sobolev.sty</samp> file and also the
+ documentation driver <samp>sobolev.drv</samp> (which you must run throught
+ LaTeX to get the documentation).
+</p>
+
+<hr />
+
+<h1><a name="graphfig">The "graphfig" package</h1>
+
+<p>
+ This package provides some very powerful commands to deal with figures
+ and graphics files in LaTeX.
+</p>
+
+<p>
+ It provides a new <samp>Figure</samp> environment and a
+ <samp>\graphfile</samp> command: the combined use of these authomatically
+ produce a correct centering of the graph(s) with respect to the page.
+ Moreover, subfigures can be handled in the same way and hard-to-discover
+ errors (such as a <samp>\label</samp> preceding a <samp>\caption</samp>)
+ are eliminated.
+</p>
+
+<p>
+ For more informations, see the <a href="graphfig.html">on-line documentation</a>
+ or download the <a href="graphfig.pdf">documentation file</a>.
+</p>
+
+<p>
+ The source file is <a href="graphfig.dtx">graphfig.dtx</a>, which also
+ deserves as an installation driver: simply run it through LaTeX in order
+ to get the corresponding <samp>graphfig.sty</samp> file and also the
+ documentation driver <samp>graphfig.drv</samp> (which you must run throught
+ LaTeX to get the documentation).
+</p>
+
+<hr />
+
+<h1><a name="dblfont">The "dblfont" package</h1>
+
+<p>
+ This package provides a simple way to define new commands whose goal
+ is to print a letter in the blackboard-bold font.
+</p>
+
+<p>
+ For more informations, see the <a href="dblfont.html">on-line documentation</a>
+ or download the <a href="dblfont.pdf">documentation file</a>.
+</p>
+
+<p>
+ The source file is <a href="dblfont.dtx">dblfont.dtx</a>, which also
+ deserves as an installation driver: simply run it through LaTeX in order
+ to get the corresponding <samp>dblfont.sty</samp> file and also the
+ documentation driver <samp>dblfont.drv</samp> (which you must run throught
+ LaTeX to get the documentation).
+</p>
+
+<hr />
+
+<h1><a name="accenti">The package "accenti"</h1>
+
+<p>
+ This package provides a shorter version of the accents-making commands
+ of LaTeX.
+ They were explicitly build for Italian language, so that only the accents
+ that occurr in it are handled (the standard LaTeX accents commands still
+ remains available, though).
+</p>
+
+<p>
+ I developed this package several years ago, when I was still dealing with
+ <tt>LaTeX2.09</tt>: now this package is <em>obsolete</em>, as it has been superseeded
+ by the standard ``<tt>inputenc</tt>'' package of <tt>LaTeX2e</tt>.
+ Indeed, the declaration
+ <pre>
+ \usepackage[latin1]{inputenc}
+ </pre><br />
+ directly allows the use of the characters ``&agrave;'', ``&egrave;'',
+ ``&igrave;'', ``&ograve;'', ``&ugrave;'' and ``&eacute;'' in the document,
+ which is extremly useful with an italian keyboard.
+</p>
+
+<p>
+ For more informations, see the <a href="accenti.html">on-line documentation</a>
+ or download the <a href="accenti.pdf">documentation file</a>.
+</p>
+
+<p>
+ The source file is <a href="accenti.dtx">accenti.dtx</a>, which also
+ deserves as an installation driver: simply run it through LaTeX in order
+ to get the corresponding <samp>accenti.sty</samp> file and also the
+ documentation driver <samp>accenti.drv</samp> (which you must run throught
+ LaTeX to get the documentation).
+</p>
+
+<hr />
+
+<h1><a name="quotes">The "quotes" package</h1>
+
+<p>
+ This package allows to use the double-quote character for both opening and
+ closing quotes: provided it is <em>always</em> used, it automatically switches
+ between opening and closing duoble-quotes.
+</p>
+
+<p>
+ For more informations, see the <a href="quotes.html">on-line documentation</a>
+ or download the <a href="quotes.pdf">documentation file</a>.
+</p>
+
+<p>
+ The source file is <a href="quotes.dtx">quotes.dtx</a>, which also
+ deserves as an installation driver: simply run it through LaTeX in order
+ to get the corresponding <samp>quotes.sty</samp> file and also the
+ documentation driver <samp>quotes.drv</samp> (which you must run throught
+ LaTeX to get the documentation).
+</p>
+
+<hr />
+
+<h1><a name="evenpage">The "evenpage" package</h1>
+
+<p>
+ This package ensures that the number of pages generated by "LaTeX" is an even
+ number: if it is odd, an empty page is added at the end, with nothing on it
+ (neither page number, headers or footers).
+</p>
+
+<p>
+ For more informations, see the <a href="evenpage.html">on-line documentation</a>
+ or download the <a href="evenpage.pdf">documentation file</a>.
+</p>
+
+<p>
+ The source file is <a href="evenpage.dtx">evenpage.dtx</a>, which also
+ deserves as an installation driver: simply run it through LaTeX in order
+ to get the corresponding <samp>evenpage.sty</samp> file and also the
+ documentation driver <samp>evenpage.drv</samp> (which you must run throught
+ LaTeX to get the documentation).

+% \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| & $\Rightarrow$ & $\mathrm{rot}$& $\nabla\wedge$& $\nabla\times$

+% ``|\usepackage|'' order, rather than in the declaration order
+% \begin{macrocode}
+%%
+\ProcessOptions*
+% \end{macrocode}
+%
+% \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.
+% \begin{macrocode}
+%%
+\newcommand\DerPar[2]{{\displaystyle\frac{\partial #1}{\partial #2}\:}}
+\newcommand\DerTot[2]{{\displaystyle\frac{d#1}{d#2}\:}}
+\newcommand\DerNorm[1]{{\displaystyle\frac{\partial #1}{\partial n}\:}}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\TendsTo}
+% The command |\@TendeQuando| must be followed by a pair of square
+% brackets, which enclose two arguments separated by a comma.
+% It place a |\rightarrow| command between them and puts the whole
+% under a bigger |\rightarrow|.
+% The |\mathop| allows the |\limits| command, which, in turn, place
+% the subscript \emph{under} the symbol.
+% \begin{macrocode}
+%%
+\def\@TendeQuando[#1,#2]{ \mathop{\longrightarrow}\limits_{#1 \rightarrow #2} }
+% \end{macrocode}
+% The |\TendsTo| command invokes |\@TendeQuando| if followed by
+% a ``['', or |\longrightarrow| otherwise.
+% \begin{macrocode}
+\def\TendsTo{\@ifnextchar[{\@TendeQuando}{\longrightarrow}}
+% \end{macrocode}
+% \end{macro}

+% \begin{macro}{\Grad}
+% The |\Grad|, |\Div| and |\Rot| commands generates a symbol or a
+% roman word, depending on the selected option.

+
+<h2>
+<a name="SECTION01">Introduction</a>
+</h2>
+This package provides some useful math-commands which are simpler to use and
+prettier then their standard LaTeX counterpart.
+
+<p>
+In particular <a href="#SECTION03b">the ``<tt>\d</tt>'' command</a> is
+redefined, so care should be taken, expecially when including this package
+in an already existent LaTeX file.
+
+<p>
+The original work of ``<tt>\d</tt>'' (i.e. place a dot under its argument)
+is now done by the ``<tt>\UnderDot</tt>'' command.
+
+<h2>
+<a name="SECTION02">The options</a>
+</h2>
+
+<p>
+At now, six options are available with the <tt>mathcmd</tt> package, which
+comes out in matched pairs.
+
+<p>
+The ``<tt>ThreeSubscrSum</tt>'' and ``<tt>TwoSubscrSum</tt>'' options control
+the placement of subscripts for
+<a href="#SECTION03c">the ``<tt>\Sum</tt>'' command</a>: 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.
+
+<p>
+The ``<tt>ProdVettWedge</tt>'' and ``<tt>ProdVettTimes</tt>'' options
+select which symbol is to be used for the
+<a href="#SECTION03f"><em>vector product</em></a>: the first one uses
+a ``<tt>\wedge</tt>'' (default), whilst the second uses a ``<tt>\times</tt>".
+
+<p>
+Finally, the ``<tt>VectOpStr</tt>'' and ``<tt>VectOpSymb</tt>'' options
+controls whether the <a href="#SECTION03f">vector-operator commands</a>
+``<tt>\Grad</tt>'', ``<tt>\Div</tt>'' and ``<tt>\Rot</tt>'' should produce
+a roman string (default) or a ``<tt>\nabla</tt>" symbol followed by an
+operator, respectively.
+
+<h2>
+<a name="SECTION03">Math-mode commands</a>
+</h2>
+
+<p>
+The <tt>mathcmd</tt> package defines a number of math-mode commands.
+
+<h3>
+<a name="SECTION03a">The <tt>text</tt> command</a>
+</h3>
+
+<p>
+The ``<tt>\text...</tt>'' command is defined to be equivalent to
+``<tt>\mbox</tt>'' (except when the ``<tt>amstext</tt>" package is also used,
+since this package already defines this command in a better way).
+
+<p>
+It is intended for inserting pieces of text in a formula.
+
+<h3>
+<a name="SECTION03b">Commands for doing integrals</a>
+</h3>
+
+<p>
+The ``<tt>\Int</tt>'' (capitalized) differs from the LaTeX command
+``<tt>\int</tt>'' in that it is always printed in <tt>displaystyle</tt> and
+if it has only a subscript, this is somewhat lowered so that it looks better.
+<pre>
+ \Int_{...}^{...} ... \d{...}
+</pre>
+
+<p>
+The <a href="#SECTION01">``<tt>\d...</tt>'' command</a> is for making the
+differential symbol at the end of integrals: it simply prints a ``<tt>d</tt>''
+followed by its argument and preceded by a little space, which seems prettier.
+
+<h3>
+<a name="SECTION03c">Commands for making sums</a>
+</h3>
+
+<p>
+The ``<tt>\Sum{...=...,...}</tt>'' command works differently, depending on
+which option between ``<a href="#SECTION02"><tt>TwoSubscrSum</tt></a>''
+(default) and ``<a href="#SECTION02"><tt>ThreeSubscrSum</tt></a>'' has been
+specified.
+
+<p>
+In the first case, it expands to
+``<tt>\displaystyle\sum_{...}={...}^{...}</tt>'', 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
+``<tt>\sum</tt>'' symbol and the ``='' is not printed.
+
+<p>
+There is also a ``<tt>\SUM...</tt>'' command which is useful when only a
+subscript is desired, irrespectively of the option specified: in fact, it
+is equivalent to ``<tt>\displaystyle\sum_...</tt>".
+
+<h3>
+<a name="SECTION03d">Derivatives symbols</a>
+</h3>
+
+<p>
+The commands ``<tt>\DerTot{...}{...}</tt>'', ``<tt>\DerPar{...}{...}</tt>'' and
+``<tt>\DerNorm{...}</tt>'' generate the symbols of total derivative, partial
+derivative and normal derivative, respectively.
+
+<p>
+In other words, they are the same as:
+<pre>
+ \displaystyle\frac{d...}{d...}
+ \displaystyle\frac{\partial ...}{\partial ...}
+ \displaystyle\frac{\partial ...}{\partial n}
+</pre>
+
+<h3>
+<a name="SECTION03e">Arrow-limits commands</a>
+</h3>
+
+<p>
+The command ``<tt>\TendsTo[...,...]</tt>'' generates a right-arrow with
+optionally an underscript wich is another smaller right-arrow between the
+two comma-separeted arguments inside the square brackets.
+
+<p>
+For example, the command ``<tt>f(x) \TendsTo[x,0] 1</tt>'' generates
+the following output:
+<pre>
+ f(x) ----------> 1
+ x --> 0
+</pre>
+
+<h3>
+<a name="SECTION03f">Vector-operators commands</a>
+</h3>
+
+<p>
+Finally, the commands ``<tt>\Grad</tt>'', ``<tt>\Div</tt>'' and
+``<tt>\Rot</tt>'' generates the strings ``grad'', ``div'' and ``rot''
+in roman type and with small spaces added before and after, if the
+``<a href="#SECTION02">VectOpStr</a>'' option is in effect (default).
+If, instead, the option ``<a href="#SECTION02">VectOpSymb</a>'' was specified,
+they generate ``<tt>\nabla</tt>", ``<tt>\nabla\cdot</tt>'' and
+``<tt>\nabla\ProdVett</tt>'' respectively.
+
+<p>
+The command ``<tt>\ProdVett</tt>'' is intended for making the symbol of
+vector product, and evaluates to ``<tt>\times</tt>'' with the option
+``<a href="#SECTION02">ProdVettTimes</a>'' and to ``<tt>\wedge</tt>''
+with the (default) option ``<a href="#SECTION02">ProdVettWedge</a>''.

+% 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).
+%
+% \StopEventually{}

+\NeedsTeXFormat{LaTeX2e}[1995/12/01]
+\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}
+%%
+\newif\if@virgolette\@virgolettefalse
+%%
+\newcommand{\@VIRGOLETTE}{%
+\if@virgolette%
+ \@virgolettefalse%
+ \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.

+% \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]| &$\Longrightarrow$& $\left\langle u,v\right\rangle_D$\\
+% \end{tabular}

+% 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

+%
+% \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).
+% \begin{macrocode}

+% 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|.

+% 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

+<h2>
+<a name="SECTION01">Introduction</a>
+</h2>
+
+<p>
+This package provides some commands which are useful when dealing with
+Sobolev spaces and their relatives.
+
+<p>
+In particular some commands are redefined, so care should be taken,
+expecially when including this package in an already existent LaTeX file.
+
+<p>
+The redefined commands are <tt>\H</tt> and <tt>\L</tt>.
+The effect of ``<tt>\H</tt>'' (which is a type of accent) can now be achieved
+by the command ``<tt>\HAccent</tt>'', whilst the job of ``<tt>\L</tt>''
+(i.e. print an ``L'' with a superimposed bar) is now done by the command
+``<tt>\Lbar</tt>''.
+
+<h2>
+<a name="SECTION02">The options</a>
+</h2>
+
+<p>
+Two options are available at the moment: <tt>DivInBrackets</tt> and
+<tt>DivAsExponent</tt>.
+They only affect the output of the ``<tt>\Hdiv</tt>'' command.
+
+<p>
+The firt options (<tt>DivInBrackets</tt>, which is the default) makes
+<tt>\Hdiv</tt> behave like ``<tt>H(div;</tt>...<tt>)</tt>'', while the
+second one (<tt>DivAsExponent</tt>) makes <tt>\Hdiv</tt> expand to
+``<tt>H^{div}(</tt>...<tt>)</tt>''.
+
+<h1>
+<a name="SECTION03">The commands</a>
+</h1>
+
+<p>
+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 <em>not</em>
+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 <tt>\H</tt>,
+<tt>\H1</tt>, <tt>\H10</tt>, etc.), the ones with the digit beeing a sort of
+abbreviation for the general one.
+
+<h3>
+<a name="SECTION03a">The <tt>\H</tt> command</a>
+</h3>
+
+<p>
+The <tt>\H</tt> 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.
+
+<p>
+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.
+
+<p>
+Here are some examples (whith the <tt>\DefaultSet</tt> set to its default
+value <tt>\Omega</tt>):
+<pre>
+ \H2 ==> H<sup>2</sup>(\Omega)
+ \H10 ==> H<sup>1</sup><sub>0</sub>(\Omega)
+ \H1[\Gamma_D] ==> H<sup>1</sup><sub>\Gamma<sub>D</sub></sub>(\Omega)
+
+ \H^{-1/2} ==> H<sup>-1/2</sup>(\Omega)
+</pre>
+
+<h3>
+<a name="SECTION03b">The <tt>\Hdiv</tt> command</a>
+</h3>
+
+<p>
+The <tt>\Hdiv</tt> 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''.
+
+<p>
+If the (default) option <tt>DivInBrackets</tt> is in effect, it differs from
+the command <tt>\H</tt> in that the word ``div'' is printed (in roman type)
+inside brackets, before the set.
+If, instead, the option <tt>DivAsExponent</tt> is active, then it is simply
+an abbreviation for <tt>\Hdiv</tt>.
+
+<p>
+Here are some examples:
+<pre>
+ DivInBrackets DivAsExponent
+ \Hdiv ==> H(div;\Omega) H<sup>div</sup>(\Omega)
+ \Hdiv0 ==> H<sub>0</sub>(div;\Omega) H<sup>div</sup><sub>0</sub>(\Omega)
+ \Hdiv[\Gamma_D] ==> H<sub>\Gamma<sub>D</sub></sub>(div;\Omega) H<sup>div</sup><sub>\Gamma<sub>D</sub></sub>(\Omega)
+</pre>
+
+<h3>
+<a name="SECTION03c">The <tt>\L</tt> command</a>
+</h3>
+
+<p>
+The <tt>\L</tt> 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 ``<tt>\infty</tt>'') the surrounding braces are optional.
+Like for the <tt>\H</tt> command, the output of <tt>\DefaultSet</tt>
+is appended.
+
+<p>
+Here are some examples:
+<pre>
+ \L2 ==> L<sup>2</sup>(\Omega)
+ \L{10} ==> L<sup>10</sup>(\Omega)
+ \L\infty ==> L<sup>\infty</sup>(\Omega)
+</pre>
+
+<h3>
+<a name="SECTION03d">The <tt>\W</tt> command</a>
+</h3>
+
+<p>
+The <tt>\W</tt> 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.
+
+<p>
+Here is an example of how it is used:
+<pre>
+ \W{k}{p} ==> W<sup>k,p</sup>(\Omega)
+ \W1\infty ==> W<sup>1,\infty</sup>(\Omega)
+</pre>
+
+<h3>
+<a name="SECTION03e">The <tt>\D</tt> command</a>
+</h3>
+
+<p>
+The <tt>\D</tt> command is used in the theory of distributions:
+it prints the space of distributions over the <tt>\DefaultSet</tt> if
+followed by a prime symbol, or its dual space, otherwise.
+<pre>
+ \D ==> <i>D</i>(\Omega)
+ \D' ==> <i>D</i>'(\Omega)
+</pre>
+
+<h3>
+<a name="SECTION03f">The <tt>\Norm</tt> command</a>
+</h3>
+
+<p>
+The <tt>\Norm</tt> 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.
+
+<p>
+Some examples:
+<pre>
+ \Norm{f(x)} ==> || f(x) ||
+ \Norm{g}[L^2] ==> || g ||<sub>L<sup>2</sup></sub>
+</pre>
+
+<h3>
+<a name="SECTION03g">The <tt>\SemiNorm</tt> command</a>
+</h3>
+
+<p>
+The <tt>\SemiNorm</tt> command is completly analoguos, but generates the
+semi-norm instead of the norm.
+
+<p>
+Some examples:
+<pre>
+ \SemiNorm{f(x)} ==> |f(x)|
+ \SemiNorm{g[H^1]} ==> |g|<sub>H<sup>1</sup></sub>
+</pre>
+
+<h3>
+<a name="SECTION03h">The <tt>\Scalar</tt> command</a>
+</h3>
+
+<p>
+The <tt>\Scalar</tt> 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).
+
+<p>
+Some examples:
+<pre>
+ \Scalar{f}{g} ==> (f,g)
+ \Scalar{u}{v}[L^2] ==> (u,v)<sub>L<sup>2</sup></sub>
+</pre>
+
+<h3>
+<a name="SECTION03i">The <tt>\Crochet</tt> command</a>
+</h3>
+
+<p>
+The <tt>\Crochet</tt> 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).
+
+<p>
+Some examples:
+<pre>
+ \Crochet{f}{g} ==> &lt;f,G&gt;
+ \Crochet{u}{v}[D] ==> &lt;u,v&gt;<sub>D</sub>
+</pre>
