% 	emlatex.tex		Version 1.1		1997 Feb 20
%
%	This TeX macro header file can be used for replacing CM fonts
%	with the EM fonts from Y&Y, Inc. in Adobe Type 1 format.
%
%	\input emlatex.tex  in your LaTeX 2.09 source file after
%	\documentstyle{...} or rename this file `emlatex.sty' and use 
%	it as a style file.  This countermands declarations in
%	`lfonts.tex'  which set up the CM fonts. 
%
%	This is for use with LaTeX 2.09 --- for plain TeX use `emplain.tex'.
%	
%	For LaTeX 2e, instead run `em.ins' on `em.dtx' and then	\usepackage{em}
%
% NOTE: Loading many new fonts on top of a predefined format may cause
%	some implementations of TeX to run out of space for fonts.
%	You may wish to create a new `TeX format' in that case using `ini TeX'
%	on lplain-e.tex (which refers to lfonts-e.tex, latex.tex, lhyphen.tex)
%	Or use a `big' TeX, or better yet a `dynamic' TeX.
%
