Create a copy of an existing repository in a new directory. The
source and destination are URLs, as passed to the repository
function. Returns a pair of repository objects, the source and
newly created destination.
The location of the source is added to the new repository's
.hg/hgrc file, as the default to be used for future pulls and
pushes.
If an exception is raised, the partly cloned/updated destination
repository will be deleted.
Arguments:
source: repository object or URL
dest: URL of destination repository to create (defaults to base
name of source repository)
pull: always pull from source repository, even in local case
stream: stream raw data uncompressed from repository (fast over
LAN, slow over WAN)
rev: revision to clone up to (implies pull=True)
update: update working directory after clone completes, if
destination is local repository
