"""
creates a CLK + TRG daisy chain using the SYNC (HDMI) ports
make_clktrg_chain UUTM UUTS1 [UUTS2..]
where UUTM is the ip-address or host name of first uut
trigger on UUTM triggers all other slaves in the chain

usage: make_clktrg_chain.py [-h] [--trg TRG] [--clk CLK] uuts [uuts ...]

make_clktrg_chain

positional arguments:

optional arguments:
  -h, --help  show this help message and exit
  --trg TRG   trigger fp|soft
