version_added: "1.6"
author: Seth Edwards
requirements:
    - urllib2
    - base64
options:
    user:
        description:
           - Librato account username
        required: true

        description:
           - Librato account api key
        required: true

        description:
            - The annotation stream name
            - If the annotation stream does not exist, it will be created automatically
        required: false
    title:
        description:
            - The title of an annotation is a string and may contain spaces
            - The title should be a short, high-level summary of the annotation e.g. v45 Deployment
        required: true
    source:
        description:
            - A string which describes the originating source of an annotation when that annotation is tracked across multiple members of a population
        required: false
    description:
        description:
            - The description contains extra meta-data about a particular annotation
            - The description should contain specifics on the individual annotation e.g. Deployed 9b562b2: shipped new feature foo!
        required: false
    start_time:
        description:
            - The unix timestamp indicating the the time at which the event referenced by this annotation started
        required: false
    end_time:
        description:
            - The unix timestamp indicating the the time at which the event referenced by this annotation ended
            - For events that have a duration, this is a useful way to annotate the duration of the event
