    Function to extract eric specific flags out of the given text.

<p>
    Flags are contained in comments and are introduced by 'eflag:'.
    The rest of the line is interpreted as 'key = value'. value is
    analyzed for being an integer or float value. If that fails, it
    is assumed to be a string. If a key does not contain a '='
    character, it is assumed to be a boolean flag. Flags are expected
    at the very end of a file. The search is ended, if a line without
    the 'eflag:' marker is found.
