# Settings for those distributing modified versions.

# It is strongly recommended that all distributors set these,
# but the only *requirement* is that modified versions that are run
# (semi)publicly give VENDOR_SOURCE to satisfy section 13 of the AGPLv3.

# TODO should these be passed to configure instead?

# This is usually one word, and does not (usually) change over time.
