env.go

// Package env is a go port of env library (https://github.com/qq1060656096/env)
//
// Examples/readme can be found on the github page at https://github.com/qq1060656096/env
//
// The TL;DR is that you make a .env file that looks something like
//
// 		SOME_ENV_VAR=somevalue
//
// and then in your go code you can call
//
// 		godotenv.Load()
//
// and all the env vars declared in .env will be available through os.Getenv("SOME_ENV_VAR")package env
