How can I switch to a tag/branch in hg?
mercurial
Solution
Once you have cloned the repo, you have everything: you can then `hg up branchname` or `hg up tagname` to update your working copy.
UP: `hg up` is a shortcut of `hg update`, which also has `hg checkout` alias for people with `git` habits.
Problem
I followed the documentation in https://developer.mozilla.org/En/Developer_Guide/Source_Code/Mercurial and downloaded FF source with: ``` hg clone http://hg.mozilla.org/mozilla-central/ src ``` How can I switch to the FF3.6 'branch' or 'tag'? The documentation said ``` hg clone http://hg.mozilla.org/releases/mozilla-1.9.2/ 192src ``` but I don't want to clone both FF main and FF3.6 twice?
