-    ${0}: create an ephemeral  prezto container using docker
-
-    usage:
-        ${0} [options] -- [addtl-args]
-
-    options:
-        -h, --help           : print this message
-        -p, --persistant     : make a persistant container
-        -N NAME, --name=NAME : set container name to NAME (default: prezto)
-        -n, --dry-run        : see what command would be run without doing so
-        -r 'CMD' --run 'CMD' : run 'CMD' on the container (quote CMD)
-        -i IMG,  --image=IMG : create container from image IMG (default hlecuanda/prezto-dev)
-        -zdotdir=PATH        : use dotfiles from local PATH
-        -zpreztodir          : override default prezto to local PATH
-
-    example:
-        ${0} -n myruncoms -zdotdir=$HOME
-
-       creates an ephemeral container named myruncoms using
-        dotfiles found in ${HOME}
 
-        ${0} -n illbeback  -p
-
-        creates a persistant container named illbeback if such
-        container exists, then startit and attach to it
-
-        ${0} -n ivebeenback -r 'apk add python'
-
-        spins up the a container named ivebeenback, and runs
-        the comand 'apk add python'. the container stops when
-        done.
