In DCL on VMS, this would look something like:

    $ INSTALL /MODULE=DockerMsftProvider /FORCE
    $ INSTALL /PACKAGE=Docker /PROVIDER_NAME=DockerMsftProvider /FORCE
    $ RESTART /NEEDED /CONTAINERS=*
    $ RESTART /SYSTEM

This is all an example to show style, not real DCL.

Part of what makes DCL great is that you use a single, consistent API to add commands and flags to the system, connect your code into the system, and then interpret them when your code gets called at runtime.

This even leads to common verbs for different purposes, making the whole system feel more unified.
