# Note on the arguments: generally speaking, it's better to use
# environment variables for private information. Environment variables
# are shielded from the process table, which is usually not private, so
# you couldn't use these tools safely on a time shared system (aka, not
# your own). Unfortunately, Foundry doesn't care about this, and
# no-one uses Seth, so we externalise this to you.
