%
% This style file modify some of the commands in epic[1] and LaTeX[2] such
% that \special commands will be generated in drawing lines if approriate.
% The \special commands generated is the subset of the \specials used
% by tpic[3].
%
% [1] epic is written by Sunil Podar. Please read epic.sty for the

% [2] LaTeX is written by Leslie Lamport. Please read the book LaTeX
% [3] tpic is modified from pic by Tim Morgan
%
%% This file contains extensions of the following epic commands:
%%      \dottedline     \dashline       \drawline
%%      \jput
%%
%% It also contains extensions of the following LaTeX commands:
%%      \circle         \line           \oval
%%
%% New commands include:
%%      \Thicklines     \arc            \ellipse
%%      \path           \spline         \allinethickness
%%
%% New commands for eepic 1.1
%%      \blacken        \whiten         \shade
%%      \texture        \filltype{type} type=black|white|shade
%%
%% For documentation, please see the accompanying manual
%%
%% Change Log;
%% o    (October 2, 88)
%%      Fixed the problem of \line (\@sline). When both x and y are
%%      large, it produced 'bad character code' error.
%%
%% o    (January 17, 89)
%%      Add commands \blacken, \whiten, \shade, \texture
%%
%% o    (January 17, 89)
%%      Add \filltype{xxxxx}
