Conventions used

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

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Add /Applications/Julian.m.app/Contents/Resources/julia/bin/Julia to make Julia available everywhere on your computer."

A block of code is set as follows:

for arg in ARGS
 println(arg)
end
 

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

julia> include("hello.jl")

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Start it up, go to Settings, and then Install Panel."
