+@subsubsection PO gettext Filter
+
+The @option{po} filter allows you to spell check GNU @code{gettext}
+@code{po} files. It will skip the header section, @code{msgid},
+@code{msgid_plural}, @code{msgctxt}, translator comments, extracted comments,
+references, flags and previous untranslated strings.
+
+The filter is tailored to translators. We offer an option to review the
+msgid and mssgid strings, but not the other strings.
