Commands are executed one at a time, and errors are checked for each command;
if any command fails unexpectedly, no subsequent commands in the script are
executed. The command prefix ! indicates that the command on the rest of the
line (typically go or a matching predicate) must fail instead of succeeding.
The command prefix ? indicates that the command may or may not succeed, but the

Note that support for modules is built into all the go commands,
not just 'go mod'. For example, day-to-day adding, removing, upgrading,

after their parent phase.

The phase runner can be bound to a cobra command; this operation sets the command description
giving evidence of the list of phases, and automatically creates sub commands
for invoking phases atomically.

Autogenerated sub commands get flags according to the following rule:

- global flags will be always inherited by autogenerated commands (this is managed by cobra)

			// If we are racing with another go command and do bin/go first,
			// then the check of bin/go above might succeed, the other go command
			// would skip its own mode-setting, and then the go command might
			// try to run a tool before we get to setting the bits on pkg/tool.
			// Setting pkg/tool before bin/go avoids that ordering problem.
			// The only other tool the go command invokes is gofmt,
