def strip_version_suffixes(path):
    """Some tarballs contain extraneous information after the version:

    * ``bowtie2-2.2.5-source``
    * ``libevent-2.0.21-stable``
    * ``cuda_8.0.44_linux.run``

    These strings are not part of the version number and should be ignored.
    This function strips those suffixes off and returns the remaining string.
    The goal is that the version is always the last thing in ``path``:

    * ``bowtie2-2.2.5``
    * ``libevent-2.0.21``
    * ``cuda_8.0.44``

    Args:
        path (str): The filename or URL for the package

    Returns:
        str: The ``path`` with any extraneous suffixes removed
