var CUSTOM_USAGE_TEXT = `` /* 1660-byte string literal not displayed */

Since Terragrunt is just a thin wrapper for Terraform, and we don't want to repeat every single Terraform command in its definition, we don't quite fit into the model of any Go CLI library. Fortunately, urfave/cli allows us to override the whole template used for the Usage Text.

TODO: this description text has copy/pasted versions of many Terragrunt constants, such as command names and file names. It would be easy to make this code DRY using fmt.Sprintf(), but then it's hard to make the text align nicely. Write some code to take generate this help text automatically, possibly leveraging code that's part of urfave/cli.
