\title{The \texttt{\thispackage} Package\footnote{This document corresponds to \texttt{lectureslides} version 1.0 / 2022-03-01.}}

\begin{document}
\maketitle
% \subsection*{Motivation}
When studying, there frequently occurs the situation where one uses \texttt{Ctrl\,+\,F} many times to search for a keyword in all the lecture slides. Throughout an entire semester, there can be a large number of PDFs that would need to be searched.
\par
This package allows for easily combining individual PDFs into a large one, indexing each with a title that PDF viewers can display. \verb+lectureslides+ also provides a table of contents.
\subsection*{Usage}
In general, usage of \texttt{\thispackage} works as follows:
\begin{verbatim}
\documentclass{article}
\usepackage{lectureslides}
\begin{document}
\course{Engineering Mechanics}
\tableofcontents
\lecture{Introduction to EM}{intro}
\lecture{Centre of gravity}{centre}
\end{document}
\end{verbatim}
\begin{macro}{\course}
Acts as the title on the cover page, used in the form \newline
\verb+\course[]{Engineering Mechanics}+. The optional argument specifies the footnote text, which otherwise defaults to \textbf{Compiled \textbackslash today}. This text adapts to an \verb+ngerman+ setting in babel.\footnote{This requires that this package is loaded after babel.}
\end{macro}
\newpage
\begin{macro}{\lecture}
Inserts one set of lecture slides. This command takes two mandatory arguments in the following form:
\begin{verbatim}
\lecture{Title of this lecture}{pdf_file_name}
\end{verbatim}
Two optional arguments can specify the range of slides that need to be included. For example, to include slides 10~--35 of \verb+intro.pdf+:
\begin{verbatim}
\lecture{Introduction to EM}[10][35]{intro}
\end{verbatim}
Either optional argument can be left empty. To include slides up to slide number 35:
\begin{verbatim}
\lecture{Introduction to EM}[][35]{intro}
\end{verbatim}
To include slides from slide number 10 til the end:
\begin{verbatim}
\lecture{Introduction to EM}[10][]{intro}
\end{verbatim}
Internally, this command calls \verb+\lecturetitle+ and \verb+\lectureslides+.
\end{macro}
\begin{macro}{\tableofcontents}
Prints a table of contents of all lectures. Each \verb+\lecture+ (and consequently \verb+\lecturetitle+) gets its own entry here. \verb+\tocline+ customises the appearance.
\end{macro}
\subsection*{Option}
\DescribeMacro{landscape}
\DescribeMacro{portrait}
\verb+landscape+ is the default orientation if no option is passed, as lecture slides are most often given out in this format. \verb+portrait+ can be used instead to insert slides in portrait orientation.
\subsection*{Advanced}
\begin{macro}{\lecturetitle}
Declares a new set of slides, but doesn't insert any PDF pages yet. When followed by \verb+\lectureslides+, an actual entry in the table of contents gets created.
\begin{verbatim}
\lecturetitle{Title of this lecture}
\end{verbatim}
\end{macro}
\begin{macro}{\lectureslides}
Inserts a set of slides from a given PDF. Optional arguments specify the range of slides to be included.
\begin{verbatim}
\lectureslides[10][35]{pdf_file_name}
\end{verbatim}
Multiple \verb+\lectureslides+ can be stringed together to include slides from different PDFs. These will then all organised under the last preceding \verb+\lecturetitle+.
\end{macro}
\begin{macro}{\tocline}
Determines how the lecture title appears in the table of contents (ToC). Putting the following in the preamble redefines this, for example:
\begin{verbatim}
\renewcommand{\tocline}[1]{%
Semana \arabic{section}: #1%
}
\end{verbatim}
Alternatively, \verb+\renewcommand{\tocline}[1]{#1}+ omits the numbering, putting only the title in the ToC.
\end{macro}
