This is a webapp to serve tax.co.
The user describes an alternate Colombian tax system to the website, which runs the microsimulation (tax.co) and gets the results to the user somehow -- maybe via email, as that would avoid a multiuser storage problem.
I did a lot of learning in folders like studies/ and django/polls/.
None of that code is needed for the app to run,
but I've kept it around for reference.
I've since changed the permissions in
django/ebdjango/settings.py and apache/apache2.conf,
which probably broke some of that legacy code that was for uploading or downloading files.
