-USAGE
-    toolboxRun -c NAME [-i NAME] [-r RELEASE] [--no-sh] [-h] [-s] [-d] [COMMANDS [ARGS...]]
-
-COMMANDS
-
-    COMMANDS to run in the container (e.g. the current active file, an external
-    build script, a program residing in the container, etc.)
-    Can be empty (default entrypoint)
-
-OPTIONS
-
-    --container NAME, -c NAME
-        Assign  a  different  NAME  to the toolbox container. This is useful for creating multiple
-        toolbox containers from the same base image, or for entirely  customized  containers  from
-        custom-built base images.
-
-        If the toolbox container NAME already exists, the command passed to toolboxRun will be
-        executed in the existing toolbox. If toolbox container NAME does not exist, it will be
-        created and the COMMAND will then be run in it.
-
-    --image NAME, -i NAME
-        Change the NAME of the base image used to create the toolbox container. This is useful for
-        creating containers from custom-built base images.
-
-    --release RELEASE, -r RELEASE
-        Create a toolbox container for a different operating system RELEASE than the host.
-
-    --ephemeral
-        The toolbox will be removed after the COMMAND is executed
-
-    --recreate
-        If the toolbox NAME already exists, it will first be removed and recreated
-
-    --no-sh, -n
-        Do not wrap COMMANDS in 'sh -c'
