.. contents::

The Cuesheet (cue) and TOC (toc) file formats both describe the layout of a CD.

Notes
=====

A Cuesheet 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

Cuesheet Format

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

TOC File Format
===============

The standard file suffix for a TOC file is ``.toc``.

Certain keywords begin a block, which must be enclosed between ``{`` and ``}``
brackets.

Comments
--------

Comments begin with ``//`` and may be placed anywhere.  Because they can be
placed anywhere in a line, toc comments are treated as a special case (not as a
keyword).  Any text beginning with ``//`` is stripped from each line.
