For each release we generate binary releases on # the thousands of machines in Unidata's vast underground complex at # an undisclosed location in the Rocky Mountains. The binary # distributions, along with the 25-foot thick cement slabs and the # giant springs, will help distribute netCDF even after a catastrophic # meteor strike.
