name
-- A possibly-wildcard-containing string giving the names of the
elements to alter. If not specified, then you must specify type
.
item
-- The name of the parameter to alter.
type
-- A possibly-wildcard-containing string giving the names of element
types to alter. May be specified with name
or by itself.
exclude
-- A possibly-wildcard-containing string giving the names of elements
to excluded from alteration.
value
-- The new value for the parameter.
differential
-- If nonzero, the new value is
the predefined value of the parameter plus the quantity given with value
.
multiplicative
-- If nonozero, the new given value is the predefined
value of the parameter times the quantity given with value
.
verbose
-- If nonzero, information is printed to the standard output describing
what elements are changed.
allow_missing_parameters
-- If nonzero, then it is not an error if an
element does not have the parameter named with item
. Normally, such
an occurence is an error and terminates the program.
