What is the canonical mercurial way to export a tree to a fresh directory, a la 'cvs export' (or 'cg export' in the git world)? The wiki <http://www.selenic.com/mercurial/wiki/index.cgi/CvsCommands> gives no equivalent for it, so maybe there isn't one except for 'hg checkout' and then tar up everything but .hg/ -Sanjoy
