% Plain text style file.

\typeout{Style option Plaintext}

% Version from John Pavel's dvidoc.sty, March 1987
% Heavily hacked by Xavier Leroy, June 1993.

% Redefine all fonts to be the "doc" pseudo-font, with fixed spacing.
% Since rm, tt and mi have different character encodings, we keep
% several copies of the doc font, with different names, so that dvi2txt
% can select the right encoding according to the name. Also, we use
% different names for boldface and italics, so that dvi2txt can select
% the right style whenever possible.
