%&lt;*preamble&gt;
%
%	(1)  If you do not already have 'fullblck.ins'
%	     run 'fullblck.dtx' through LaTeX to create it.
%
%	     Now run 'fullblck.ins' through (La)TeX to get the package.
%
%	     [Or use 'docstrip' and extract 'fullblck.sty' from 'fullblck.dtx'
%	     using option 'package']
%
%	(2)  Then run 'fullblck.dtx' three times thought LaTeX
%	     to get the documentation 'fullblck.dvi'.

%
% \begin{abstract}
% This article describes the \texttt{fullblck} package which modifies
% the \texttt{letter} class to use a full block layout.
% Specifically, this means that the return address,
% date and closing will be set at the left margin.
% \end{abstract}
%
% \section{Introduction}
% In the US, there are three common layouts used for business letters.
% \LaTeX2e's \texttt{letter} class implements the indented layout.
% This package modifies
% \LaTeX2e's \texttt{letter} class to set the letter in the fullblock
% layout.  No attempt is made to support the semi-block layout.
%
%
% \section{How to use the package}
%
% Add \texttt{\char92usepackage\{fullblck\}} to the preamble of your letter.
% No options are required or supported, and no new commands are defined.
%
% \section{The implementation}
%
% First, the basic boilerplate for a \textsc{sty} file:
%
%    \begin{macrocode}
%&lt;*package&gt;
\NeedsTeXFormat{LaTeX2e}[1996/06/01]
\ProvidesPackage{fullblck}
  [1998/11/17 v1.1 JHCloos FullBlock Style for Letters]
%    \end{macrocode}
%
% Now we set the \texttt{\char92longindentation} to zero;
% this puts the closing at the left margin.
%
%    \begin{macrocode}
\longindentation=0pt%
%    \end{macrocode}
%
% Finally we redefine \texttt{\char92opening} to just dump the return
% address and date at the left margin in \texttt{\char92raggedright}
% mode.
%
%    \begin{macrocode}
\renewcommand*{\opening}[1]{\ifx\@empty\fromaddress
  \thispagestyle{firstpage}%
    {\raggedright\@date\par}%
  \else  % home address
    \thispagestyle{empty}%
    {\raggedright\ignorespaces
      \fromaddress \\*[2\parskip]%
      \@date \par}%
  \fi
  \vspace{2\parskip}%
  {\raggedright \toname \\ \toaddress \par}%
  \vspace{2\parskip}%
  #1\par\nobreak}
%&lt;/package&gt;
%    \end{macrocode}
%
%
% \Finale
