There are also analogous settings to @code{ragged-right} and

@code{ragged-bottom} and @code{ragged-last-bottom}. If set to

The @code{Page_turn_engraver} reads the context property
@code{minimumPageTurnLength} to determine how long a note-free section must
be before a page turn is considered. The default value for

The within-system vertical spacing mechanisms are controlled by
two sets of grob properties. The first set is associated with the
@code{VerticalAxisGroup} grob, which is created by all staves and
spaced. Note that @code{@var{item2}} is not necessarily below
@code{@var{item1}}; for example,
@code{nonstaff-relatedstaff-spacing} will measure upwards from the
-non-staff line if @code{staff-affinity} is @code{#UP}.

+
+Initially, the @code{staff-staff-spacing} of a
+@code{VerticalAxisGroup} is a Scheme function that applies the
+properties of the @code{StaffGrouper} if the staff is part of a
+group, or the @code{default-staff-staff-spacing} of the staff
+otherwise. This allows staves to be spaced differently when they
+are grouped. For uniform spacing regardless of grouping, this
+function may be replaced by a flexible-spacing alist, using the
+complete-redefinition form of override shown above.
@item default-staff-staff-spacing
-The settings to use for @code{staff-staff-spacing} when it is
