.. contents::

The Cue Sheet (cue) and Table of Contents (toc) file formats both describe the
layout of a CD.

Notes
=====

A cue or toc file has an (optional) global section, followed by any number of
track sections.

Lines (with a few exceptions for the toc format) begin with a keyword, which
may be followed by whitespace separated fields.  Some keywords are only allowed
in the global section or a track section.

Format Notation
---------------

A string may be enclosed in single or double quotation marks.  If the string
contains whitespace, it must be enclosed in quotation marks.

``<field>``
	a required field
``[field]``
	an optional field
``...``
	preceding field may be repeated any number of times

Cue Sheet Format
================

The standard file suffix for a cue file is ``.cue``.
