Total:        total strings that are not obsolete

Translated:   strings that have been translated

Untranslated: strings that have no translation (may be finished)

Unfinished:   strings that have not been marked as finished (may or
              may not have a translation)

Obsolete:     strings were translated, but these translations are no
              longer used in the source (frequently happens after
              someone edits a text to make a correction)
