mercurial-git - 0.8.12-1+deb10u1 main

The Hg-Git plugin for Mercurial adds the ability to push and pull to/from
a Git server repository. This means you can collaborate on Git based
projects from Mercurial, or use a Git server as a collaboration point
for a team with developers using both Git and Mercurial.
.
The plugin can convert commits/changesets losslessly from one system to
another, so you can push via a Mercurial repository and another
Mercurial client can pull it and their changeset node ids will be
identical - Mercurial data does not get lost in translation.
