As described in the introduction, Jujutsu automatically rewrites the current
checkout with any changes from the working copy. That works well while you're
developing that revision. On the other hand, if you check out some existing
revision, you generally don't want changes to the working copy to automatically
rewrite that revision. Jujutsu has a concept of "open" and "closed" revisions to
solve this. When you check out a closed revision, Jujutsu will actually create a
new, *open* revision on top of it and check that out. The checked-out revision
is thus always open. When you are done making changes to the currently
checked-out revision, you close it by running `jj close`. That command then
updates to the rewritten revision (as most `jj` commands do), and since the
rewritten revision is now closed, it creates a new open revision on top. If you
check out a closed revision and make changes on top of it that you want to go
into the revision, use `jj squash`.
