For example:
% make clean
% make stage
And then configure 3 FLUs:
% echo '{p_srvr, a, machi_flu1_client, "localhost", 39000, []}.' > rel/machi/etc/flu-config/a
% echo '{p_srvr, b, machi_flu1_client, "localhost", 39001, []}.' > rel/machi/etc/flu-config/b
% echo '{p_srvr, c, machi_flu1_client, "localhost", 39002, []}.' > rel/machi/etc/flu-config/c
And then configure a chain to use 2 of those 3 FLUs:
% echo '{chain_def_v1,c1,ap_mode,[{p_srvr,a,machi_flu1_client,"localhost",39000,[]},{p_srvr,b,machi_flu1_client,"localhost",39001,[]}],[],[]}.' > rel/machi/etc/chain-config/c1
... then start Machi e.g.
% ./rel/machi/bin/machi console
... you should see the following console messages scroll by (including a :
=PROGRESS REPORT==== 8-Dec-2015::22:01:44 ===

{machi_flu_psup,start_link,
[a,39000,"./data/flu/a",[]]}},
{restart_type,permanent},
{shutdown,5000},
{child_type,supervisor}]
[... and also for the other two FLUs, including a bunch of progress
reports for processes that started underneath that sub-supervisor.]
