Environment variables

tofutf can be configured from environment variables. Arguments can be converted to the equivalent env var by prefixing it with tofutf_, replacing all - with _, and upper-casing it. For example:

• --secret becomes tofutf_SECRET
• --site-token becomes tofutf_SITE_TOKEN

Env variables can be suffixed with _FILE to tell tofutf to read the values from a file. This is useful for container environments where secrets are often mounted as files.
