#203: Add shallow clone to hg ---------------------------+------------------------------------------------ Reporter: eric9 | Owner: eric9 Type: defect | Status: new Priority: minor | Milestone: Component: GetComponents | Version: Keywords: | ---------------------------+------------------------------------------------ Git and darcs offer a shallow clone option (--depth 1 for git and --lazy for darcs). Hg can accomplish a similar thing by running hg clone -r tip URL. This should be implemented following the same rules as shallow clones for git and darcs.
