\maketitle
\begin{abstract} %%% \noindent
  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 
  `\\' 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 
%  \tracingmacros=1 \tracingonline=1
  behavior, maybe limited to certain parts of the 
  document source.\\ 
  [It works!] 
  It may also be useful with active characters in lieu of `\\', 
  e.g., the double quote `"' with \ctanpkgref{german}`.sty'
  or \ctanpkgref{babel}.
  \par\smallskip\noindent
\strong{Keywords:}\quad 
    macro programming, optional command arguments, 
    manual line breaks

\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}.
