[IPOL discuss] demo base class and git submodules

[Juan Cardelino]

Dear all,
            The previous email from Nicolas raised a forgotten issue
for me: the size of the code needed to build your own demo. I used a
pretty old version of the base class for a long time because I didn't
wan't to re-download everything. It would be nice to have only the
base class and maybe one or two demos in the main repo, but we
certainly don't need to download all demos with their corresponding
images and stuff. I suggest to use git submodules for the different
user demos. In this way, you can download the base class and an
example to get started and later on you can download the rest. The
demos would be in a completely separated git repo, but downloadable
from the main one.
What do you think?
Best regards,
                   Juan
