\maketitle
\begin{abstract}\noindent
'monofill.sty' addresses horizontal alignment with plain text 
as in the result of \LaTeX's `\listfiles'. 
%% 2012/10/30:
In the first instance, it has been developed as the shared 
tool to adjust each column with the \ctanpkgref{nicefilelist} package.
%% /2012/10/30
It may also be useful for alignment in typesetting monospaced 
characters as in figure tables, for simulating a typewriter, 
or for code listings. 
v0.2 in fact provides a tool for use with the               %% 2012/10/30
\ctanpkgref{hardwrap} package that in turn has been made for console output. 
The implementation also has ``philosophical aspects" 
in avoiding use of a counter register.

\section{Features and Usage}
\subsection{Summary of Features}
A command |\MFfieldtemplate| sets the maximum width of a ``field" 
using a template, 
with an optional argument for the ``filler" token.
Then |\MFleftinfield| and |\MFrightinfield| types given 
(one-line) text and adds ``filler" tokens to the left or right, 
until the entire number of tokens es the number of characters 
in the associated template. So this is a kind of analogue to 
`\settowidth{\mylength}{<template>}', 
`\makebox[\mylength][l]{<text>}', and
`\makebox[\mylength][r]{<text>}'
intended for plain text output, without typesetting.
See Sec.~\ref{sec:user} for details.

\subsection{``Philosophical aspects"}
The package also has ``philosophical" aspects: \ 
1.\enspace Apart from the declaration of the width of a ``field", 
everything is \strong{expandable} (thinking of application with 'blog.sty' 
of the \ctanpkgref{morehype} bundle) and thus is a kind of 
\Wikienref{functional programming}. \ 
2.\enspace Actually, \strong{no counter} is used, 
and we seem to \emph{count without} using the \emph{concept of ``number."}
\
Rather, we \ (a)\enspace just generate a new list from a given one such 
that both have the same length and \ 
(b)\enspace compare the lengths of two lists---both (a) and (b) 
without \emph{determining} the length (which would be a \emph{number}) 
of any list. 

\subsection{Installing and Calling}
The file 'monofill.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}           %% corr. 2011/02/08

%% extended 2011/01/14:
Below the `\documentclass' line(s) and above `\begin{document}',
you load 'monofill.sty' (as usually) by
\begin{verbatim}
  \usepackage{monofill}
\end{verbatim}
For certain uses such as with \ctanpkgref{fileinfo}, 
the package is better loaded by 
\begin{verbatim}
  \RequirePackage{monofill}
\end{verbatim}

\subsection{Examples}
\subsubsection{Typewriter}
% \MFfieldtemplate{tt}{leftright}
% \MFfieldtemplate[\ ]{tt}{leftright}
% \MFfieldtemplate[~]{tt}{leftright}
% \MFfieldtemplate[X]{tt}{leftright}
With both \[`\MFfieldtemplate[\MFspace]{tt}{leftright}'  \]
and       \[`\MFfieldtemplate[\MFenspace]{tt}{leftright}'\]
followed by 
\begin{verbatim}
\begin{quotation}\tt\noindent
  !leftright!\\
  !\MFleftinfield{left}{tt}!\\
  !\MFrightinfield{right}{tt}!\\
  !\MFrightinfield{rightleft}{tt}!
\end{quotation}
\end{verbatim}
I get
% \MFfieldtemplate[\MFspace]{tt}{leftright}
\MFfieldtemplate[\MFenspace]{tt}{leftright}
% \MFfieldtemplate[\MFotherspace]{tt}{leftright}
%% <- works to
% \MFfieldtemplate[\enspace]{tt}{leftright}
% \MFfieldtemplate[\kern.5em ]{tt}{leftright}
% \renewcommand*{\MFfillelement}{\kern.5em }
% \renewcommand*{\MFfillelement}{\hphantom\enspace}
\begin{quotation}\tt\noindent
%   \enspace leftright\\
  !leftright!\\
  !\MFleftinfield{left}{tt}!\\
  !\MFrightinfield{right}{tt}!\\
  !\MFrightinfield{rightleft}{tt}!
%   \enspace \MFrightinfield{rightleft}{tt}
\end{quotation}
\subsubsection{Figures}
Similarly, with
`\MFfieldtemplate[\MFenspace]{figs}{0000}'
and
\begin{verbatim}
\begin{quote}\noindent
  \MFrightinfield{1}{figs} is one,\\
  \MFrightinfield{10}{figs} is ten,\\
  \MFrightinfield{100}{figs} is hundred,\\
  \MFrightinfield{1000}{figs} is thousand.
\end{quote}
\end{verbatim}
I get
\MFfieldtemplate[\MFenspace]{figs}{0000}
\begin{quote}\noindent
  \MFrightinfield{1}{figs} is one,\\
  \MFrightinfield{10}{figs} is ten,\\
  \MFrightinfield{100}{figs} is hundred,\\
  \MFrightinfield{1000}{figs} is thousand.
\end{quote}
\subsubsection{Screen Output}
Finally, try 
\begin{verbatim}
\MFfieldtemplate{screen}{0000}
  \typeout{\MFrightinfield{1}{screen} is one,}
  \typeout{\MFrightinfield{10}{screen} is ten,}
  \typeout{\MFrightinfield{100}{screen} is hundred,}
  \typeout{\MFrightinfield{1000}{screen} is thousand.}
\typein{OK?}
\end{verbatim}
It works, believe me.
% \MFfieldtemplate{screen}{0000}
%   \typeout{\MFrightinfield{1}{screen} is one,}
%   \typeout{\MFrightinfield{10}{screen} is ten,}
%   \typeout{\MFrightinfield{100}{screen} is hundred,}
%   \typeout{\MFrightinfield{1000}{screen} is thousand.}
% \typein{OK?}

\section{Credit}
The package actually is motivated by good ideas of 
\ctanpkgauref{muench-hm}{Martin M\"unch}'s about 
extending the \ctanpkgref{longnamefilelist} package.
