pulpcore.plugin.stages

Plugin writers can use the Stages API to create a high-performance, download-and-saving pipeline to make writing sync code easier. There are several parts to the API:

1. declarative-version is a generic pipeline useful for most synchronization use cases.
2. The builtin Stages including artifact-stages and content-stages.
3. The stages-api, which allows you to build custom stages and pipelines.
