Problems with "end" callback in Python

[Hemant Goyal]

Hi,

I think INDEX_MARK could be used to mark off positions in your text to
indicate to speech-dispatcher when to return to the callbacks.

I read about that in the python api documentation :

 INDEX_MARK = 'index_marks'
    """Index mark events are reported when the place they were
    included into the text by the client application is reached
    when speaking them"""

On the flip side, I think your text buffer might become overfilled with
these index markers, and you will also have to neglect them when you re
printing the text on screen.

Best,
Hemant
