Usage:
  seabox ssh-exkeys [OPTIONS]

Options:
  -v            : verbose mode
  -p password   : the password used to connect to hosts
  -h host       : the new host to connect to (multiple -h is okay)
  -f hostfile   : a file listing all new hosts to connect to
  -e hostfile   : a file listing all existing hosts for expansion
  -x hostfile   : a file listing all new hosts for expansion
  --help        : show this help, then exit
            
Each line in a hostfile is expected to contain a single host name.  Blank
lines and comment lines (beginning with #) are ignored.  The name of the
local host (as provided by hostname) is included automatically and need not 
be specified unless it is the only host to process.  During cluster expansion, 
the local host is always considered an existing host and should not be specified
in the "new host" list.  Duplicate host names in either the new host list (-h, 
-f, -x options) or the existing host list (-e option) are ignored. The same host 
name cannot appear in the both the new and existing host lists. Host names 
including a user name or port (username@hostname:port) are not accepted.
