It would be useful if torbrowser-launcher functions where available by command line or by environment variables.

My use cases:

• In Whonix-Workstation I'd like to use torbrowser-launcher to pre-install TBB-stable using a build script.

(I keep care of the start-tor-browser script, which will hopefully be removed from TBB by upstream and the new tor-laucher addon tpo is working on can be disabeld using an environment variable. Connections to 127.0.0.1:9150 get redirected to Whonix-Gateway.)

• in Whonix-Gateway I'd like to use torbrowser-launcher to pre-install and update the pluggable transports bundle.

(Not because I want to use it on the Gateway. Only because it contains latest pyobfsproxy, which is otherwise difficult to download, install, update using scripts.)
