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: "When the Master receives a connection then it looks in its manifests (starting from /etc/puppet/manifests/site.pp) what resources have to be applied for that client host, also called node."

A block of code is set as follows:

class my_users {
  @user { 'al': […] tag => 'admins' }
  @user { 'matt': […] tag => 'developers' }
  @user { 'joe': [… tag => 'admins' }
[ … ]
}

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

ls -l $(facter rubysitedir)/puppet/provider/package/
