%% 이 스타일은 setspace 6.7을 바탕으로, memoir의
%% 출력루틴을 hooking하여 거의 동일하게 동작하도록
%% 수정한 스타일이다.
%% memoir 클래스에서 memhangul 스타일을 사용했을 때
%% 불린다. 다른 용도로는 사용할 수 없음.

%% This style is a modified version of SETSTYLE ver 6.7 by Erica M. S. Harris
%% modified by Karnes Kim
%%
%% FEATURES:
%%    all the features of setstyle package
%%
%%	  NEW FEATURES:
%%
%%		1. [nofloatspacing] option
%%			disables the feature of SETSTYLE, turning off all the line spacing
%%			in the floats(figures, tables) and footnotes.
%%      \noadjustfloatfnspacing, \adjustfloatfnspacing
%%		2. [hangul] option
%%			When [hangul] option is on, the basic line spreading is set to
%%			a proper line spacing in Korean(Hangul) documents, which has
%%			a wider gap between the lines.
%%      \SetHangulspace
%%		3. quote and quotation environment
%%			quote and quotation environment have the same line spacing 
%%			with the floats and footnotes, verse.
%%      \noadjustquotespacing, \adjustquotespacing
%%		4. [adjustfootnotesep] option
%%			this option is meaningful only when [hangul] is on and 
%%			[nofloatspacing] off.
%%		5. [adjustverbatim] option.
%%			verbatim environment.
%%      \SetHangulVerbatimSpace.
%%    6. \ResetHangulspace, \RestoreHangulspace

% ** Modification of the LaTeX command \@setsize.

%---Stretch the baseline BEFORE calculating the strut size. This improves
%   spacing below tabular environments etc., probably...
%   Comments are welcomed.

% GT:  Sun 29 Sep 1996:  Question:  Is this code anywhere near correct
% since this part of LaTeX (in, eg, latex.ltx) has been greatly changed?

% GT:  Sun 29 Sep 1996:  The meanings of the arguments to \@setsize
% appear to be (whatever these may signify) :
% current size; font baselineskip; ignored (!); and font size.

% GT:  Sun 29 Sep 1996:  Note that \@setsize (in latest LaTeX,
% \@setfontsize, which is called by \@setsize) seems to be the only
% place in purely modern LaTeX where \@currsize is set, and ltxguide.cls
% seems to be the only file in the LaTeX base distribution that uses it!

% GT:  Wed 24 Jan 1996:  This footnote code was copied from LaTeX and
% modified rather naively.  It had to be brought up to date, not only

% been major changes to this code in LaTeX at least as far back as
% March 1992.

% Normal, bottom of the page, footnotes.
%
% GT:  Based HEAVILY on original LaTeX (2e) code.  A standard hook would
% be MUCH preferred, so that LaTeX's footnote implementation needn't be
% copied each time it changes.
%
% GT:  The \protected@edef requires at least the December 1994 LaTeX.
% This is precisely the kind of VERSION DEPENDENCY situation that
% cannot (AFAIK) be avoided, because LaTeX (2e) LACKS appropriate
% standard hooks and/or context markers.
