% \mdqon \MakeNotSkipping"{\rq\rq} (``Uwe L"uck" )
The 'ifnextok' package deals with the behavior of
\LaTeX's internal `\@ifnextchar' to skip blank spaces.
This sometimes has surprising or for some users really
\emph{unwanted} effects, especially with brackets following
`\\' when %% v0.1a: was `where'
the user does \emph{not} intend to specify an
optional argument, rather wants that brackets are \emph{printed.}
The package offers commands and options for modifying this
behavior, maybe limited to certain parts of the document source.\\
[It works!]
It may also be useful with active characters in lieu of `\\',
% \mdqon
e.g., the double quote `"' with \ctanpkgref{german}`.sty'
or \ctanpkgref{babel}.
v0.3 fixes behavior in non-typesetting mode with
`\MakeNotSkipping', using a somewhat different technique
than \LaTeX's robustifications.
% `\DeclareRobustCommand'.

\section{Installing and Calling}
The package file `ifnextok.sty' is provided ready,
installation only requires putting it somewhere where \TeX\ finds it
(which may need updating the filename data
base).\urlfoot{ukfaqref}{inst-wlcf}
Below the `\documentclass' line(s) and above `\begin{document}',
you load `ifnextok.sty' (as usually) by
\[`\usepackage{ifnextok}'\qquad \mbox{or by}\qquad
`\usepackage[<options>]{ifnextok}'\]---<options> described
in Section~\ref{sec:options}. E.g., the \emph{main goal} of
writing the package is achieved by
\[`\usepackage[stdbreaks]{ifnextok}'\]
