Description

when using curl, or a command line client (say a automated update bot) the error message is hard to understand (or even see)
my solution was to do the following

which puts the traceback at the start and end of the HTML page as a comment so that the developer can just see it quickly.

This is an interesting idea, but I don't think it's worth adding.

It would be rather trivial (by now), since there is a text template already, which is used for AJAX: ​https://github.com/django/django/blob/586bf15f6f061b4fa99866fbfd9b33ae08789676/django/views/debug.py#L90

This could additionally check the user agent then.

I think it is very useful when developing.
