How to set environment variable in supervisord using output from a file

Question

What is the good way to set environment variable in supervisord using output from a file? I need like:

[program:prog1]
command=prog1 -param1 -param2
environment=PASSWORD=`cat .password`

I can use an additional script, but perhaps the better way exists:

[program:prog1]
command=start-prog1

start-prog1:

export PASSWORD=`cat .password`
start-prog1

Environment variables that are present in the environment at the time that supervisord is started can be used in the configuration file using the Python string expression syntax %(ENV_X)s:

You can use (in Bash)

export PASSWORD1=$(cat .password)

Then use this in the configuration file

environment = PASSWORD=%(PASSWORD1)s

I need to use different environment variables for each process, because some process can be started on a host and each process should have own password, that is impossible if I'll use one scrip for exporting variable and supervizord for starting processes.

This does not work in Supervisor 3.2.
