 Add role in the 'see also' section in the help page

This massive update have been done with the following code:
FILES=$(find modules/ -iname '*.xml' -type f|grep "/help/pt_BR")
for f in $FILES; do
    perl -0777 -pe 's/<refsection>([^<]*)<title>Ver Também<\/title>/<refsection role="see also">\n<title>Ver Também<\/title>/gi' $f > $f.2
    mv $f.2 $f
done

(just replace pt_BR by fr_FR or en_US)
