Other options from SUPPORTED_OPTIONS may be present, but are ignored. For lines that do not contain requirements, the only options that have an effect are from SUPPORTED_OPTIONS. Options from SUPPORTED_OPTIONS_REQ may be present, but are ignored.

The only allowed format for environment variables defined in the requirement file is `${MY_VARIABLE_1}` to ensure two things: 1. Strings that contain a `$` aren't accidentally (partially) expanded. 2. Ensure consistency across platforms for requirement files. These points are the result of a discussion on the `github pull request #3514 <https://github.com/pypa/pip/pull/3514>`_. Valid characters in variable names follow the `POSIX standard <http://pubs.opengroup.org/onlinepubs/9699919799/>`_ and are limited to uppercase letter, digits and the `_` (underscore).
