Time for action – listing LaTeX packages

We shall create a list of packages that we got to know in the previous chapter:

1. Begin a new document and enter the following code:

   \documentclass{article}
   \begin{document}
   \section*{Useful packages}
   LaTeX provides several packages for designing the layout:
   \begin{itemize}
     \item geometry
     \item typearea
     \item fancyhdr
     \item scrpage2
     \item setspace
   \end{itemize}
    \end{document}

2. Typeset and have a look at the output:

   

What just happened?

It was not necessary to load any package. We began with a heading followed by some text. For the actual list, we used an environment called itemize. As we know about environments, \begin{itemize} starts it and \end{itemize} ends it. The command \item tells LaTeX that a new item to the list follows. Each item may contain text of any length and even paragraph breaks. Well, that's pretty easy, isn't it?

Nesting lists

When a list gets longer, we could make it clearer by dividing it. We just create lists in a list. It's...
