</synopsis>
<p>This template returns a numeric index of a plural form for a given language,
similarly to how indexes are used in gettext PO files. Different languages have
different rules for plurals. Some languages have no plurals at all, while others
have as many as six different forms. This plural form index is used by
<code xref="l10n.gettext">l10n.gettext</code> to determine the correct string to use.</p>
<p>The rules in this template are hand-written. They are not taken from the PO
files. They are written by referencing the PO files in various GNOME modules,
as well as the plural rules in the Unicode CLDR.</p>
