-ADD_THIS_TRANSLATOR (Score_engraver);
+This engraver decides whether a column is breakable. The default is
+that a column is always breakable. However, when every Bar_engraver
+that does not have a barline at a certain point will call
+Score_engraver::forbid_breaks to stop linebreaks. In practice, this
+means that you can make a breakpoint by creating a barline (assuming
+that there are no beams or notes that prevent a breakpoint.)
