mutool trace
============

The ``trace`` command prints a trace of all the device calls used to render a page.

.. code-block:: bash

	mutool trace [options] file [pages]

``[options]``
	Options are as follows:

	``-p`` password
		Use the specified password if the file is encrypted.
	``-W`` width
		Page width in points for EPUB layout.
	``-H`` height
		Page height in points for EPUB layout.
	``-S`` size
		Font size in points for EPUB layout.
	``-U`` filename
		User CSS stylesheet for EPUB layout.
	``-X``
		Disable document styles for EPUB layout.
	``-d``
		Use display list.

``file``
	Input file name. The file can be any of the supported input formats.

``[pages]``
	Comma separated list of page ranges. The first page is "1", and the
	last page is "N". The default is "1-N".

The trace takes the form of an XML document, with the root element being the
document, its children each page, and one page child element for each device
call on that page.
