How to create documents programmatically?

To create documents programmatically, the following must be done:

Have the initial parameters, path of the binary and title. If the document to be created has no binary, path can contain the empty string.

path = '/var/www/athentose/media/uploads/ejemplo.pdf'
title = 'Ejemplo titulo.pdf'

Have the space and type of document available:

serie = Serie.objects.get(name='facturas')
doctype = DocumentType.objects.get(name='tipo_factura')

Create the document

doc = serie.load_file(path, title, doctype)

The returned object shall be a document (File entity).
