Set logging options for daml script calls?

How does one customize the logback options when running daml script?

I found that I can edit the ~/.daml/sdk/x.y.z/daml-sdk/script-logback.xml.

Still curious if there is a way to do this on the daml script command line.

You can set the location of a custom logback file on the command line like this:

_JAVA_OPTIONS="-Dlogback.configurationFile=my-script-logback.xml" daml script  ...

You can get a starter file to customize from ~/.daml/sdk/x.y.z/daml-sdk/script-logback.xml.

It works the same way for daml sandbox, of course.
