By default, when importing data (like CSV import) with the ``base_import``
module, Odoo follows this rule:
1. If you import the XMLID of a record, make an **update**.
2. If you do not, **create** a new record.
This module allows you to set additional rules to match if a given import is an
update or a new record.
This is useful when you need to sync heterogeneous databases, and the field you
use to match records in those databases with Odoo's is not the XMLID but the
name, VAT, email, etc.
After installing this module, the import logic will be changed to:
1. If you import the XMLID of a record, make an **update**.
2. If you do not:
1. If there are import match rules for the model you are importing:
1. Discard the rules that require fields you are not importing.
2. Traverse the remaining rules one by one in order to find a match in
the database.
1. If one match is found:
1. Stop traversing the rest of valid rules.
2. **Update** that record.
2. If zero or multiple matches are found:
1. Continue with the next rule.
3. If all rules are exhausted and no single match is found:
1. **Create** a new record.
2. If there are no match rules for your model:
1. **Create** a new record.
