I spent quite a while searching through the source tree for random-number resources yesterday and never found it. I just grepped through ecos.db and through all the filenames in the source tree and didn't get any hits on the string 'random' or 'RANDOM'. I also grepped through all of the c/c++ files and never found the string '/dev/random'. It seems to be well hidden... -- Grant Edwards grante Yow!
