% pkletter.sty 17 May 89.
% Created by Phil Kearns
%	Based on letter.sty of 21 Jul 85
%	from the original LaTeX distribution.
%
% Defines a single new command for the LaTeX letter style, \myblurb,
% whose single argument specifies the contents of an hbox of length
% \textwidth as the header on the first page of the letter.  The size
% and placement of the hbox is designed to make the following header
% blurb look nice:
%
%	\myblurb{
%	\makebox[1in][l]{\special{psfile=/usr/lib/tex/macros/collins_seal.ps
%	       hscale=0.5 vscale=0.5 voffset=-79}}
%	\raisebox{0.6in}{
%	\parbox[t]{2.5in}{\setlength{\baselineskip}{12pt}
%	{\tensl Phil Kearns \\ Department of Computer Science \\
%	The College of William and Mary \\ Williamsburg, Virginia 23185}}}
%	\hfill
%	\raisebox{0.6in}{
%	\parbox[t]{2in}{\setlength{\baselineskip}{12pt}
%	{\tensl \mbox{} \\
%	Phone: (804) 253--4781 \\
%	Internet: kearns\symbol{'100}cs.wm.edu \\
%	\mbox{}}
%	}}}
%
% If you use another blurb, you may have to tweak positioning.
