Envkey secures and simplifies configuration and secrets management.

EnvMem allows you to dump your GC.stat information from a long-running server, then produce a simple shellscript to set up your Ruby memory environment variables to match that configuration. This improves startup time slightly and allows you finer-grain control over your memory setup. If you've ever found Ruby memory environment variables on a web page and used them to try to speed up your app, this is a better approach.

Access environment variables. Also includes presence validation, type coercion and default values.
