Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "A maintainers file offers a list of contributors to a particular board support."

A block of code is set as follows:

sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"
sudo apt-get update
sudo add-apt-repository "deb http://people.linaro.org/~neil.williams/lava jessie main"
sudo apt-get update
  
sudo apt-get install postgresql
sudo apt-get install lava
sudo a2dissite 000-default
sudo a2ensite lava-server.conf
sudo service apache2 restart

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

sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"
sudo apt-get update
sudo add-apt-repository "deb http://people.linaro.org/~neil.williams/lava jessie main"
sudo apt-get update
  
sudo apt-get install postgresql
sudo apt-get install lava
sudo a2dissite 000-default
sudo a2ensite lava-server.conf
sudo service apache2 restart

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

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.1 LTS"
