Defines the drops to [@c]simulate, to [@c]collect results from or to [@c]query/[@c]eval/[@c]dump
results from. This option is only applicable to the simulation method
independent replication. A drop consists of exactly one result phase.

A drop is specified by a seed part which denotes which seed values are used
for the simulation.

The seed part may be given as a sequence of a single number ("5"), a list of
numbers ("[1,2,3]"), a range of numbers ("[1-5]") or a mixture of lists and
ranges ("[1-3,6,8]"). Ranges and lists are enclosed in "[" and "]".

For the simulate command, only a single number (no list and no
range) is allowed for specifying the drop count (number of drops to
handle). For the [@c]query/[@c]eval/[@c]dump commands drops may be selected by 
lists/ranges of seed numbers.
