To do

redtape should be considered in Alpha status: things may break, and test coverage is low. The following tasks are planned for a 1.0.0 release:

• Increase and track test coverage.
• Documentation.
• Support for wildcard (*) in specification file.
• Support for ownership.
• Support for ASSUMEROLE.
• Support for EXTERNAL objects.
• Complete support for mypy static type-checking.
