Usage: lsh [OPTIONS] localhost|lh COMMAND [...]

This is a "local shell" command that works like a remote shell but only for the
local host.  This is useful for rsync testing or for running a local copy where
the sender and the receiver need to use different options (e.g. --fake-super).

Options:

-l USER        Choose the USER that lsh tries to become.
--no-cd        Skip the chdir \$HOME (the default with hostname "lh")
--sudo         Use sudo -H -l USER to become root or the specified USER.
--rrsync=DIR   Test rrsync restricted copying without using ssh.
--rropts=STR   The string "munge,no-del,no-lock" would pass 3 options to
               rrsync (must be combined with --rrsync=DIR).

The script also ignores a bunch of single-letter ssh options.
