Once you've initialized it (and cloned the review data repo to a place

See the following help topics if you want to use the command-line
interface:
- hg help review-review
- hg help review-comment
- hg help review-signoff
- hg help review-check
Once you've reviewed some changesets don't forget to push your comments and
signoffs so other people can view them.
