Returns a ParsedRequirement object if the line is a requirement line, otherwise returns None. For lines that contain requirements, the only options that have an effect are from SUPPORTED_OPTIONS_REQ, and they are scoped to the requirement. 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. These lines may contain multiple options (although our docs imply only one is supported), and all our parsed and affect the finder.

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).
