Version 1.12, 6/30/2009:

Major changes:

Added the ability to simulate RIL and multiple-strain RIL in the
sim.cross function. For the case of multiple-strain RIL, one needs
genotype data on the founder strains, which may be simulated with
the new function simFounderSnps. The encoding of genotypes in
multiple-strain RIL is quite complicated. See the help file for
sim.cross.

Added the ability to deal with 4- and 8-way RIL in calc.genoprob,
sim.geno, argmax.geno, est.map, ripple, est.rf, tryallpositions,
calc.pairprob, and calc.errorlod.

Added a function, readMWril, for reading data on 4- or 8-way RIL.

Fixed a minor problem in read.cross, with format="csv", in the case
of many phenotypes that resulted in *really* slow data import. (To
read a file with 200 individuals and 1500 phenotypes, it would take
about 60 seconds and now takes about 2 seconds.)

Added the ability to have scanone and scantwo permutations run in
parallel, if the snow package is installed. The added argument
n.cluster indicates the number of parallel nodes to use.
