About rentry
rentry is the official Python client set for Rentry.co, a markdown powered paste and publishing service that offers preview, custom URLs and editing. The repository ships two things: rentry.py , a complete command line tool contained in a single file with no dependencies, and rentry client , an installable library that wraps the same API for programmatic use. Both default to the hosted instance at https://rentry.co, and the shared configuration lets the base protocol and base URL be repointed elsewhere, such as a local development server.
