The purpose of this tool is to analyze the OpenCloud Groupware backend source code to extract information about the REST APIs it exposes, and to render those into OpenAPI.
The motivation for implementing a piece of custom software to do so is to avoid repetition and other error prone practices that are required by the use of a generic solution such as go-swagger, and instead making use of the conventions as well as the understanding of the underlying framework implemented in the Groupware backend in order to minimize annotation efforts.
