HOSTRANGED SUPPORT
Multiple hosts can be input either as an explicit comma separated lists of hosts or a range of hostnames in the general form: prefix[n-m,l-k,...], where n < m and l < k, etc. The later form should not be confused with regular expression character classes (also denoted by []). For example, foo[19] does not represent foo1 or foo9, but rather represents a degenerate range: foo19.

This range syntax is meant only as a convenience on clusters with a prefixNN naming convention and specification of ranges should not be considered necessary -- the list foo1,foo9 could be specified as such, or by the range foo[1,9].

Some examples of range usage follow:
    foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
    foo[7,9-10] instead of foo7,foo9,foo10
    foo[0-3] instead of foo0,foo1,foo2,foo3
