python3-notmuch2 0.30-1ubuntu1 (amd64 binary) in ubuntu groovy

 Notmuch is a system for indexing, searching, reading, and tagging
 large collections of email messages in maildir or mh format. It uses
 the Xapian library to provide fast, full-text search with a very
 convenient search syntax.
 .
 This package provides a Python 3 interface to the notmuch
 functionality using CFFI bindings, which interface with a shared
 notmuch library.
 .
 This is the preferred way to use notmuch via Python.
