The `notebeamer` Package
========================

The `notebeamer` package provides a method for inputting slides on note
papers quickly.

Overview
--------

The package provides the `\includebeamer` macro

    \includebeamer [&lt;keyvals&gt;] {&lt;filename&gt;} [&lt;keyvals&gt;]

to set the format that how the slides is arranged on note papers.

See `notebeamer.pdf` for more. Happy TeXing!

%
% \section{Introduction}
%
% The \pkg{notebeamer} package provides an easy way to input slides on note
% pages quickly, developed by \pkg{expl3} based on \pkg{tikz} and
% \pkg{l3graphics}. It supports various compilation methods, such as
% \hologo{pdfLaTeX}, \hologo{XeLaTeX}, \hologo{ApLaTeX}, \hologo{LuaLaTeX}, etc.
%
% \section{Usage}
%
% To load this package, write the line
% \begin{quote}
%   |\usepackage{notebeamer}|
% \end{quote}
%
% \begin{function}{\includebeamer}
%   \begin{syntax}
%     \cs{includebeamer} \oarg{keyvals} \marg{filename} \oarg{keyvals}
%   \end{syntax}
%   The \cs{includebeamer} command can create pages with note lines, and import
%   the specific pages of the \file{.pdf} file on the left side of the note
%   pages. The mandatory argument can set the \file{.pdf} file that will be
%   inserted. The optional argument accepts the following keys
%   \begin{keyval}
%     \item [\key{color}] \val{str} can set the note lines' color
%     (Default: black), this key's name could be omitted.
%     \item [\key{ratio}] \val{fp num} can set imported slides' ratio and empty
%     area's width (Default: |0.5|).
%     \item [\key{sep}] \val{dim} can set the vertical space between slides
%     (Default: |2ex|).
%     \item [\key{nup}] \val{int} can set the number of slides on every page
%     (Default: |3|).
%     \item [\key{pages}] \val{comma-separated list} can select pages to insert.
%     The list could contain ranges of page numbers.
%     (Default: |1|).
%     \item [\key{lhead, rhead}] \val{str} can set the left / right header of
%     the pages.
%   \end{keyval}
% \end{function}
%
% Additionally, \cs[no-index]{newgeometry} could be used for assistance. Such as
% \begin{verbatim}
%   \newgeometry{margin = .75in}
%   \includebeamer
%     [ nup = 4, pages = {2-4, 6},  lines = 32, ratio = .28,
%       Navy,    lhead = Chapter 1, rhead = Page~\thepage
%     ] { example-image-a4-numbered.pdf }
% \end{verbatim}
% \newgeometry{margin = .75in}
% \includebeamer
%   [ nup = 4, pages = {2-4, 6},  lines = 32, ratio = .28,
%     Navy,    lhead = Chapter 1, rhead = Page~\thepage
%   ] { example-image-a4-numbered.pdf }
