It be great to be able to access the demo started with `python demo.py`
from a remote host. The user should be warned that the demo shouldn't be
used for production use.

Hi Karl-Phillip,

thanks for trying roundup.

You can change the default settings of the demo by changing
web= setting in demo/config.ini

Listening to all interfaces would be something like:
web = http://0.0.0.0:8917/demo/

Where do you suggest we mention this?

Actually this is documented at 
http://roundup-tracker.org/docs/installation.html#for-the-really-impatient

Where would you have expected it instead or in addition?

Right!

I was checking out `demo.py --help`. Is this ticket sufficient to
request adding that info (or a link to it) to the output of `--help` or
should I open another one.

This ticket is sufficient.

Next step would be to come up with a text or
even better with a patch against head. :)

There also is a hint about the config section in the startup message of demo.py.

I have added a pointer to docs/installtion to demo.py -h as well
with hg4988:c3a647a9f387.

Thanks again Karl-Phillip for the pointer!
Bernhard
