Repository clone
Appearance
A Repository clone is a concept from distributed revision control which represents the cloning of a remote software repository to a local copy.
Semantics
A clone operation is performed when a developer want to start working on an existing project.
Usage by DVCSs
A few tools actually have a clone command: Monotone (mtn), Mercurial (hg), git, and Bazaar (an alias for branch).
SVK simply calls it mirror.
