Git is best thought of as a tool for storing the history of a
collection of files. It does this by storing compressed snapshots of

If you're releasing a new version of a software project, you may want

Dangling objects are not a problem. At worst they may take up a little

If you and the maintainer both have accounts on the same machine, then
you can just pull changes from each other's repositories directly;

However, the more common way to do this is to maintain a separate public
repository (usually on a different host) for others to pull changes
from. This is usually more convenient, and allows you to cleanly

As with git-fetch, you may also set up configuration options to
save typing; so, for example, after
