\begin{abstract}
For most purposes, the features of \cmd{newcommand} suffice.
Nonetheless, \cmd{newcommand} lacks some interesting features like
the ability to make definition global or to use the \cmd{protected}
prefix supplied by \eTeX. This---surprisingly small---package makes
possible to pass an~optional argument \cmd{newcommand} so that is
becomes possible to use the \cmd{global} and \cmd{protected}
prefixes.
\end{abstract}
\section{Usage}
Load the package with
%
\begin{texcode}
\cmd[1]{usepackage}{xnewcommand}
\end{texcode}
%
Then \cmd{newcommand} can take an additional optional argument:
%
\begin{texcode}
\cmd[syntax,5]{newcommand}[prefix]{command}[number][default]{definition}
\end{texcode}
%
where \meta{prefix} can be any valid prefix or combination of them:
%
\begin{description}
\item [\cmd{long}] The command will accept `long arguments', in
other words, its arguments may contain ends
of paragraph (explicit \cmd{par} or empty
lines);
\item [\cmd{global}] The command is defined globally, in other
words, the definition won't be confined to
the current group;
\item [\cmd{protected}] The command will be robust in moving
arguments and won't undergo systematic
expansion at the beginning of tabular cells;
\item [\cmd{outer}] Makes the macro \cmd{outer} (not very useful,
but included for the sake of completeness).
\end{description}
The same syntax applies to the commands \cmd{renewcommand},
\cmd{DeclareRobustCommand}, \cmd{newenvironment} and
\cmd{renewenvironment}.
\section{Remarks}
It should not break anything. The normal syntax is preserved:
%
\begin{texcode}
\cmd[syntax,2]{newcommand}{command}{definition}
\end{texcode}
%
is equivalent to
%
\begin{texcode}
\cmd[3]{newcommand}[\cmd{long}]{\<command\>}{\<definition\>}
\end{texcode}
%
and
%
\begin{texcode}
\cmd[syntax,2]{newcommand}*{command}{definition}
\end{texcode}
%
is equivalent to
%
\begin{texcode}
\cmd[3]{newcommand}[]{\<command\>}{\<definition\>}
\end{texcode}
%
Any macro that uses \cmd{star@or@long} will inheritate the features
described above.
\section{Examples}
Global definition:
%
\begin{texcode}
\cmd{newcommand}[\cmd{global}]\marg{command}\marg{definition}
\end{texcode}
%
Protected definition:
%
\begin{texcode}
\cmd{newcommand}[\cmd{protected}]\marg{command}\marg{definition}
\end{texcode}
%
Combination of both:
%
\begin{texcode}
\cmd{newcommand}[\cmd{global} \cmd{protected}]\marg{command}\marg{definition}
\end{texcode}
