[BaseCommand](https://github.com/django/django/blob/master/django/core/management/base.py)

is a [Django](/django.html) object for creating new Django admin commands

that can be invoked with the `manage.py` script. The Django project team

as usual provides

[fantastic documentation](https://docs.djangoproject.com/en/dev/howto/custom-management-commands/)

for creating your own commands. There are also some well-written community

tutorials on the subject such as

[How to Create Custom Django Management Commands](https://simpleisbetterthancomplex.com/tutorial/2018/08/27/how-to-create-custom-django-management-commands.html)

by Vitor Freitas.

[django-filer](https://github.com/divio/django-filer)

([project documentation](https://django-filer.readthedocs.io/en/latest/))

is a file management library for uploading and organizing files and

images in Django's admin interface. The project also installs a few

Django `manage.py` commands to make it easier to work with the files

and images that you upload.
