<note>
<p>
In some Linux distributions, not all formats are supported by default, so you might not be able to view all the formats listed above.
</p>
<p>
Support for a format is called a <em>backend</em>.  If you get the error "Unable to Open Document", you may wish to check whether the backend package for the format is installed.
