werkzeug.debug.repr
~~~~~~~~~~~~~~~~~~~
This module implements object representations for debugging purposes.
Unlike the default repr these reprs expose a lot more information and
produce HTML instead of ASCII.
Together with the CSS and JavaScript files of the debugger this gives
a colorful and more compact output.
