The LEADING package
v0.3

Defines the \leading{&lt;length&gt;} command to set the
leading of the document to the length specified. In
contrast with \linespread{&lt;ratio&gt;}, which is less
useful in most cases.

% \section{Introduction}
%
% \LaTeX\ defines two methods of specifying \emph{leading}\footnote{Pronounced to rhyme with `sledding'; the word arises from the spacers of lead used to separate lines of text in traditional metal press typesetting}, or the distance between successive lines of text:
% \codeline {\cmd\linespread\marg{ratio to original} , and\DescribeMacro{\linespread}}
% \codeline {\cmd\renewcommand\cmd\baselinestretch\marg{ratio to original} .\DescribeMacro{\baselinestretch}}
% (I've got no idea what the difference between the two methods actually is.)
%
% For example, in the \pkg{pracjourn} class, 
% a font size and leading of 12\,pt/15.5\,pt was chosen, which required the preamble declaration
% |\linespread{1.069}|, because the default leading for a 12\,pt document is 14.5\,pt and $14.5\times 1.069\approx15.5$. 
%
% But this is not how most people define the typesetting of their paragraphs.
% Instructions don't come from the designer: ``increase the leading 1.069 times the standard size in a 12\,pt document''. Instead, it's common to see ``give me a leading of 15.5\,pt''. And indeed, that's how
% \LaTeX's \cmd\fontsize\ command works.
%
% This package defines the \cmd\leading\marg{length}\DescribeMacro{\leading}\ command, 
% which sets the leading immediately to the \meta{length} specified. Here's an example:\bigskip
%
% \noindent
% \begin{minipage}[t]{0.49\linewidth}
% |\leading{11pt}|\par\noindent\small\leading{11pt}
%Upon observing him more closely, I perceived that he wore a black silk
%apron over his small-clothes; and this was a thing which I thought very
%odd. Before I had time to make any remark, however, upon so singular a
%circumstance, he interrupted me with a second \emph{``ahem!''}
% \end{minipage}\hfill
% \begin{minipage}[t]{0.49\linewidth}
% |\leading{5mm}|\par\noindent\small\leading{5mm}
%Upon observing him more closely, I perceived that he wore a black silk
%apron over his small-clothes; and this was a thing which I thought very
%odd. Before I had time to make any remark, however, upon so singular a
%circumstance, he interrupted me with a second \emph{``ahem!''}
% \end{minipage}
%
% \section{Notes}
%
% The \cmd\leading\ command will ignore spaces after it. 
%
% As \cmd\leading\ uses \cmd\linespread\ internally, the results
% of |\leading{15.5pt}| in a 12\,pt document and |\linespread{1.069}|
% are identical. This means that the leading at other font sizes (\eg, |\small|, |\large|)
% will also be adjusted by the same ratio.
%
% Since \cmd\leading\ uses a fixed length, if the
% font size of the document changes then its value will need to be
% adjusted. This isn't a problem in general, however, because it is common
% for different ratios of linespread to be used for different absolute
% font sizes anyway.
