Name: !="" & !~"^[$]"

// Setenv defines a set of command line flags, the values of which will be set
// at run time. The doc comment of the flag is presented to the user in help.

// To define a shorthand, define the shorthand as a new flag referring to
// the flag of which it is a shorthand.
Setenv: {
	$id: "tool/os.Setenv"

	{[Name]: Value}
}

// Getenv gets and parses the specific command line variables.

// Environ populates a struct with all environment variables.
Environ: {
	$id: "tool/os.Environ"

	// A map of all populated values.
	// Individual entries may be specified ahead of time to enable
	// validation and parsing. Values that are marked as required
	// will fail the task if they are not found.
