	TerragruntConfigPath string

	// Location of the original Terragrunt config file. This is primarily useful when one Terragrunt config is being
	// read from another: e.g., if /terraform-code/terragrunt.hcl calls read_terragrunt_config("/foo/bar.hcl"),
	// and within bar.hcl, you call get_original_terragrunt_dir(), you'll get back /terraform-code.

	// Current Terraform command being executed by Terragrunt
	TerraformCommand string

	// Original Terraform command being executed by Terragrunt. Used to track command evolution as terragrunt chains
	// different commands together. For example, when retrieving dependencies, terragrunt will change the
	// TerraformCommand to `output` to run `terraform output`, which loses the context of the original command that was
	// run to fetch the dependency. This is a problem when mock_outputs is configured and we only allow mocks to be
	// returned on specific commands.
	// NOTE: For `xxx-all` commands, this will be set to the Terraform command, which would be `xxx`. For example,
	// if you run `apply-all` (which is a terragrunt command), this variable will be set to `apply`.

	// A command that can be used to run Terragrunt with the given options. This is useful for running Terragrunt
	// multiple times (e.g. when spinning up a stack of Terraform modules). The actual command is normally defined
