# More on: Extending LaTeX using packages

The \usepackage command takes a comma-separated list of packages, so you can load several in one go: \usepackage{color,graphicx} for example. If you are passing options to a package, they will apply to each of the packages in the list. It’s also easier to comment out packages if they are loaded separately. So we will stick to loading each package on a separate line.

## The babel package

We showed the babel package in the main lesson as a way to choose different hyphenation patterns. It does a lot more than that, depending on the language(s) being used. For example, in German, it provides some shorthands for creating ‘soft’ hyphens, and also a way to quickly type umlauts without needing a German keyboard.

\documentclass{article}

\usepackage[ngerman]{babel} % Notice that the option name is 'ngerman'

\begin{document}

H"ohe

\end{document}


Other language settings make design changes: for example, in traditional French typography, there is a space before some punctuation signs, like :, and this is added automatically if you load babel with the option french.

## Global options

Sometimes, you want an option to be available to all of the packages you’ve loaded. That is done by giving it on the \documentclass line: every package can ‘see’ this list. So to pass the language of a document to all packages, we might use:

\documentclass[ngerman]{article}

\usepackage{babel} % Notice that the option name is 'ngerman'

\begin{document}

H"ohe

\end{document}
