+%
+% \maketitle
+%
+% \begin{abstract}
+%
+% The \textsf{namespc} package adds rudimentary \emph{c++}-like namespace
+% functionality to \LaTeX. It may be used to declare local \LaTeX{} commands,
+% which can be made accessible in a later contexts without defining them
+% globally.
+%
+% \end{abstract}
+%
+% \section{Introduction}
+% This package can be used to declare local \LaTeX{} commands,
+% which may be reused in a later context without polluting the global
+% namespace, as an equivalent to \emph{c++}-like namespaces.
+%
+% \section{Usage}
+%
+% \DescribeMacro{\namespace}
+% This command is used to instantiate and reuse a certain namespace.
+% The |\namespace| command has the following syntax:
+%
+% |\namespace{|\emph{spcname}|}{|\emph{before}|}{|\emph{body}|}|
+%\\
+% The first parameter corresponds to the name of the namespace
+% to be started or used.
+% The \emph{before} arguments of the current call of |\namespace| are appended
+% to the preamble of namespace \emph{spcname}, which is processed
+% before the text in \emph{body} gets processed.
+%
+% \DescribeEnv{\emph{spcname}}
+% With the first call of
+% |\namespace{|\emph{spcname}|}{|\ldots|}{|\emph{\ldots}|}| the
+% corresponding environment \emph{spcname} is defined which processes
+% all \emph{before} arguments within its preamble.
+%
+% \DescribeMacro{\namespace*}
+% Essentially the same as the |\namespace| command but without generation
+% of the corresponding environment.
+%
+% \DescribeMacro{\usingnamespace}
+% By using |\usingnamespace{|\emph{spcname}|}| one can force \LaTeX{} to
+% process the namespace preamble of \emph{spcname}.
+%
+% \StopEventually{\PrintChanges\PrintIndex}
+%
+% \section{Implementation}
+%
+% We first make |@| to a character in order to use and define internal
+% commands:
+%
+% \begin{macrocode}
+\makeatletter
+% \end{macrocode}
+%
+% \begin{macro}{\@defnamespace@ifundef}
+%
+% First we define an internal macro which will be used to instatiate the
+% (internal) namespace preamble macro |\@namespace@|\emph{spcname}
+%
+% \begin{macrocode}
+\def\@defnamespace@ifundef#1{
+ \@ifundefined{#1}{
+ \long\expandafter\def\csname#1\endcsname{}
+ }{}
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@n@mesp@cestar}
+% Now we are able to define the internal version of the starred |\namespace|
+% command.
+%
+% \begin{macrocode}
+\newcommand{\@n@mesp@cestar}[3]{
+ \@defnamespace@ifundef{@namespace@#1}
+ \expandafter\g@addto@macro\csname @namespace@#1\endcsname{#2}%
+ {
+ \expandafter\relax\csname @namespace@#1\endcsname
+ #3
+ }
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\usingnamespace}
+% The user command |\usingnamespace| just forces initiatiation and processing
+% of the namespace preamble.
+%
+% \begin{macrocode}
+\newcommand{\usingnamespace}[1]{
+ \@defnamespace@ifundef{@namespace@#1}
+ \csname @namespace@#1\endcsname
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@provide@namespace@env}
+% This is an internal command which provides the corresponding environment.
+%
+% \begin{macrocode}
+\def\@provide@namespace@env#1{
+ \@ifundefined{#1} {
+ \newenvironment{#1}{\usingnamespace{#1}}{}
+ }{}
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\::}
+% The double colon notation may be used to access commands defined within a
+% namespace preamble once. Note that the command's arguments have to be
+% surrounded by colons:
+% \begin{macrocode}
+\def\::#1::#2:#3:{%
+ {\csname @namespace@#1\endcsname
+ \csname#2\endcsname#3}
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@n@mesp@ce}
+% Next we just add the definition of the respective environment to |\namespace*|
+% in order to obtain the internal version of |\namespace|:
+%
+% \begin{macrocode}
+\newcommand{\@n@mesp@ce}[3]{
+ \@provide@namespace@env{#1}
+ \@n@mesp@cestar{#1}{#2}{#3}
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\namespace}
+% Finally we use the |\@ifstar| macro to define the user commands
+% |\namespace| and |\namespace*|:
+%
+% \begin{macrocode}
+\newcommand*{\namespace}{\@ifstar\@n@mesp@cestar\@n@mesp@ce}
+% \end{macrocode}
+% \end{macro}
+% |@| is made special character again:
+% \begin{macrocode}
+\makeatother
+% \end{macrocode}
+%
+% \section{Example}
+%
+% This is example code for the use of the \textsf{namespc}~package:
+%
+%\begin{verbatim}
+%\namespace{spcname}
+%{\newcommand{\spcwidecmd}{\emph{command}\xspace}}{
+% Using \spcwidecmd for the first time.
+%} % end of namespace
+%
+% % not defined here: \spcwidecmd
+%
+%\namespace{spcname}{}{
+% \spcwidecmd may be used again later.
+%} % end of namespace
+%
+%\begin{spcname}
+% We can also use \spcwidecmd within the corresponding environment\ldots
+%\end{spcname}
+%
+% Alternatively we may use the double colon notation: \::spcname::spcwidecmd::
+%
+%\usingnamespace{spcname}
+%\ldots{} or globally: \spcwidecmd.
+%
+%\end{verbatim}
+%
+% And here's the corresponding \LaTeX{} output:
+% \\
+%\namespace{spcname}
+%{\newcommand{\spcwidecmd}{\emph{command}\ }}{
+%
+% Using \spcwidecmd for the first time.
+%}
+%
+%
+%\namespace{spcname}{}{
+% \spcwidecmd may be used again later.
+%}
+%
+%\begin{spcname}
+% We can also use \spcwidecmd within the corresponding environment\ldots
+%\end{spcname}
+%
+% Alternatively we may use the double colon notation: \::spcname::spcwidecmd::
+%
+%\usingnamespace{spcname}
+%\ldots{} or globally: \spcwidecmd
+%
+% \Finale
+%
+% \endinput
