I'm looking to set up custom build environments.

To set up custom build environments, you can define them in your .travis.yml file. You can specify different language versions, services, and environment variables. Would you like an example?

Yes, please provide an example of a .travis.yml file.

Here's a simple example:

language: python
python:
  - "3.8"
  - "3.9"
services:
  - docker
env:
  global:
    - MY_ENV_VAR=value

This sets up Python 3.8 and 3.9 with Docker support.
