# Test pseudorandom number generation.
# In this process random numbers are generated
# in the TestRandomNumberServiceAnalyzer.  The
# state of the random number engines is saved in
# two places.  The states are saved in a text file
# that gets overwritten before modules process each
# event. The states are also saved into every event
# and luminosity block.

# The analyzer also writes each generated random number
# to a text file named testRandomService.txt, which
# can be examined to determine that the expected
# sequence of numbers has been generated.

    # Next we specify a seed or seeds for each module that
    # uses random numbers.

    # Optionally, one can specify different types
    # of engines.  Currently the only three types
    # implemented are HepJamesRandom, RanecuEngine, and
    # TRandom3.  If you do not specify the engine, it
    # defaults to HepJamesRandom.

    # Use the parameter initialSeed for engines requiring
    # only one seed and initialSeedSet for the other ones.
    # HepJamesRandom requires one seed between 0 and 900000000
    # RanecuEngine requires two seeds between 0 and 2147483647
    # TRandom3 will take any 32 bit unsigned integer.
