Is it possible to set a StringMap() from environment?

[scudette]

If I define a StringMap() I can set multiple key/value pairs by repeating the flag:

 --flag foo=bar --flag baz=bar

But this can not work with environment variables because you can only have one variable of the same name:

APP_FLAG=foo=bar

I could not find a way to set the second parameter with the env var - is this supported? I tried to add a \n to it but it didnt work.

You should be able to set APP_FLAG to a newline separated list:

APP_FLAG="foo=bar
baz=bar"
