Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here’s an example: “You can access each package’s documentation by calling texdoc at the command line.”

A block of code is set as follows:

\documentclass{article}\begin{document}\end{document}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

\begin{figure}[htbp!]  \centering  \includegraphics{filename}  \caption{Some text}  \label{fig:name}\end{figure}

Any command-line input or output is written as follows:

$ bibtex document

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here are some examples:

“Artificial Intelligence (AI) refers to machine or software-simulated intelligence.”

“Click the editGPT button to enable the editing mode.”
