Re: Lump commit HOWTO?

Hi All,

I have a specific workflow in mind that I'm not entirely sure how to
accomplish with git.  What I'd like to do is track a project in a
local branch, and do commits of my own there as well.  Then when I'm
ready to submit the work, I want to take all the incremental commits
and lump them into a single new commit and push that out as a patch or
into a branch for people to pull from.

See git merge --squash. It is exactly that.
Also git-rebase --interactive and git cherry-pick -n can help you to
get the same.
