        Compare a Requirement to any other object that has at least these attributes: name, epoch,
        version, and release. This method will return a negative value if self is "less than" other,
        0 if they are equal, and a positive value if self is "greater than" other. For example,
        a Requirement that references Firefox-23.0 compared to a Unit that references Firefox-23.1
        would return a negative value.

        The other object must have the same name as the Requirement, as it
        doesn't make sense to ask whether an object is greater or less than a Requirement when it
        has a different name. For example, a Requirement might reference Firefox-23.0, and other
        might be the package openssh-server-6.2. If this Requirement is asked to compare itself with
        openssh-server, it will raise ValueError.
