<p>
	The following table details the current state of the translations of the
	LyX GUI for the LyX stable branch (currently $lyx_version).
	Unfortunately, only a few languages are well-supported. The LyX team may,
	therefore, decide to exclude some of the translations from a formal
	release in order not to confuse the user with a strongly mixed-language
	interface.
</p>
<p>
	Explanation:
</p>
<ul>
	<li><i>Translated:</i> The number of translated messages</li>
	<li><i>Fuzzy:</i> The number of fuzzy messages; these are not considered
	    for LyX output but solely serve as a hint for the translators</li>
	<li><i>Untranslated:</i> The number of untranslated messages; the
	    default language (i.e., English) will be used in the LyX outputs</li>
</ul>
