Greetings!

I have a question regarding openSUSE build service command-line tool or osc.

I was trying to create a release workflow for a package so I experimented with it in this repository https://github.com/uncomfyhalomacro/hellorust. Does osc support environmental variables? Because I want that I can use them as part of the `env` section on the config YAML file so that I can do the following

```sh
OSC_USERNAME=yourusername OSC_PASSWORD=yourpassword osc co home:yourusername/projectname

cd home:yourusername/projectname

# do some bunch of stuff here
OSC_USERNAME=yourusername OSC_PASSWORD=yourpassword osc vc -m "somemessage" projectname.changes projectname.spec

OSC_USERNAME=yourusername OSC_PASSWORD=yourpassword osc commit

# done committing new release to devel project for projectname

```

Or maybe extend the `osc token --operations` functionality that includes checkout, service, and commit?

I will be waiting for your reply.

Sincerely,

Soc Virnyl S. Estela
