-overridden to print, for example, the number of systems or the system
-number of a grob.
+After a line break, some function may called by overriding
+@code{after-line-breaking-callback}. This can be most useful to assertain
+that a piece uses a specified number of lines; typically the number of
+lines (or systems) is not engraved, but it can be printed to console when
+generating the output. The number of lines may be associated either
+to the number of systems or the system number of a grob.
