git-email 1:2.17.1-1ubuntu0.11 (amd64 binary) in ubuntu bionic

 Git is popular version control system designed to handle very large
 projects with speed and efficiency; it is used for many high profile
 open source projects, most notably the Linux kernel.
 .
 Git falls in the category of distributed source code management tools.
 Every Git working directory is a full-fledged repository with full
 revision tracking capabilities, not dependent on network access or a
 central server.
 .
 This package provides the git-send-email program for sending series of
 patch emails.
