module: aci_contract
short_description: Manage contract resources on Cisco ACI fabrics (vz:BrCP)
description:
- Manage Contract resources on Cisco ACI fabrics.
- More information from the internal APIC class I(vz:BrCP) at
  U(https://developer.cisco.com/docs/apic-mim-ref/).
author:
- Dag Wieers (@dagwieers)
version_added: '2.4'
notes:
- This module does not manage Contract Subjects, see M(aci_contract_subject) to do this.
  Contract Subjects can still be removed using this module.
- The C(tenant) used must exist before using this module in your playbook.
  The M(aci_tenant) module can be used for this.
