Vagrant is a tool for building and distributing development environments.

Vagrant::Plugin::V2::Command#split_main_and_subcommand

This method will split the argv given into three parts: the
flags to this command, the subcommand, and the flags to the
subcommand. For example:

    -v status -h -v

The above would yield 3 parts:

    ["-v"]
    "status"
    ["-h", "-v"]

These parts are useful because the first is a list of arguments
given to the current command, the second is a subcommand, and the
third are the commands given to the subcommand.
