rclap a new configuration management for rust, is now on crates.io

Introduction Every deployment requires a set of environment variables to run correctly. Instead of scattering these across multiple files and manually tracking what each pod needs, we maintain a single centralized configuration file that serves as the definitive source for all required environment variables. This approach provides two key benefits: Easy to check : Developers and operators can quickly identify what environment variables are required by any pod by referring to a single source Easy to hand over : When deployment configurations need to change, everything is consolidated in one place Whether you're using Helm charts or other deployment tools, having a centralized configuration file simplifies the management of environment variables and arguments that are passed to your applications. This eliminates the need to coordinate across multiple configuration files and ensures consistency across environments. Traditional clap struggles with this separation. Configuration is primaril
