# You need to use this script once to build a set of devrels for prior
# releases of Riak (for mixed version / upgrade testing). You should
# create a directory and then run this script from within that directory.
# I have ~/test-releases that I created once, and then re-use for testing.
#
# See rtdev-setup-releases.sh as an example of setting up mixed version layout
# for testing.

# Different versions of Riak were released using different Erlang versions,
# make sure to build with the appropriate version.

# This is based on my usage of having multiple Erlang versions in different
# directories. If using kerl or whatever, modify to use kerl's activate logic.
# Or, alternatively, just substitute the paths to the kerl install paths as
# that should work too.
