  else
    range_arg = "-r '#{from}:#{to || head}'"
  end
  scm cvs_root, :log, range_arg
end

#query_revision(revision) ⇒ Object

Unfortunately, cvs doesn’t support the concept of a revision number like subversion and other SCM’s do. For now, we’ll rely on getting the timestamp of the latest checkin under the revision that’s passed to us.
