Usage: %F{2}z4h%f %Bssh%b [%Ussh-options%u]... [--] [%Uuser@%u]%Uhostname%u

Connect to the remote host over SSH and start Zsh with local configs.
The remote host must have internet access, standard POSIX utilities
and directories, and a login shell compatible with the Bourne shell
(sh, bash, zsh, ash, dash, etc.) or csh/tcsh. Nothing else is required.

Here's what %F{2}z4h%f %Bssh%b does in more detail:

  1. Archives Zsh config files on the local host and sends them to the
     remote host.
  2. Extracts Zsh config files on the remote host.
  3. Sources %U.zshenv%u with Z4H_BOOTSRAPING=%F{3}'1'%f, which starts the usual
     %Bzsh4humans%b bootstrap process.

The first login to a remote host may take some time. After that it's
as fast as normal %F{2}ssh%f.
