- Implement a `ingest` subcommand that takes a list of file names on the command line and can also read from standard input - Each files content should be read and ingested into feed-to-sqlite compatible sqlite db - Default to using `prompthound.db` in the OS specific user directory - Accept an option `--db` that should be a path to an sqlite db to install the data, initialize the feed schemas if necessary, - If the '--db` argument points to an existing file, prompt the user whether they want to overwrite the db - Write appropriate tests for the ingest process and the cli invocation. - There is test data in the `tests/data` subdirectory. The pluralistic gzip is one rss file. The sample_rss.tar.gz is a collection of multiple rss files - If there is a unique identifier for a feed item, make sure it only exists in the db once - Add tests for error handling
