r"""Return full path to the user-specific data dir for this application.

        "appname" is the name of application.
        "appauthor" (only required and used on Windows) is the name of the
            appauthor or distributing body for this application. Typically
            it is the owning company name.
        "version" is an optional version path element to append to the
            path. You might want to use this if you want multiple versions
            of your app to be able to run independently. If used, this
            would typically be "<major>.<minor>".
        "roaming" (boolean, default False) can be set True to use the Windows
            roaming appdata directory. That means that for users on a Windows
            network setup for roaming profiles, this user data will be
            sync'd on login. See
            <http://technet.microsoft.com/en-us/library/cc766489(WS.10).aspx>

    Typical user data directories are:
        Mac OS X:               ~/Library/Application Support/<AppName>
        Unix:                   ~/.config/<appname>    # or in $XDG_CONFIG_HOME if defined
        Win XP (not roaming):   C:\Documents and Settings\<username>\Application Data\<AppAuthor>\<AppName>
        Win XP (roaming):       C:\Documents and Settings\<username>\Local Settings\Application Data\<AppAuthor>\<AppName>
        Win 7  (not roaming):   C:\Users\<username>\AppData\Local\<AppAuthor>\<AppName>
        Win 7  (roaming):       C:\Users\<username>\AppData\Roaming\<AppAuthor>\<AppName>

    For Unix, we follow the XDG spec and support $XDG_CONFIG_HOME. We don't
    use $XDG_DATA_HOME as that data dir is mostly used at the time of
    installation, instead of the application adding data during runtime.
    Also, in practice, Linux apps tend to store their data in
    "~/.config/<appname>" instead of "~/.local/share/<appname>".
