+/*
+Gebug is a tool that makes debugging of Dockerized Go applications super easy by enabling Debugger and Hot-Reload features, seamlessly.
+
+
+The implementation is based on utilizing Docker and Docker-Compose to manage the debugging environment.
+In order to get a consistent and clean environment, the application build is taking place inside a Docker container.
+This make the debugging process agnostic to the host's libraries and tools versions. For instance, you can choose to work a specific
+version of Go on your host, but use another one when debugging your application.
+
+
+How it works
+
+During the `init` process, the user sets the desired configuration to the project including
+Docker base, environment variables and expose ports.
+When the user runs `start` (unless explicitly asked) a `Dockerfile` and `docker-compose.yml` with the relevant configuration
+including one-direction source files synchronization between the host and the runtime container and auto-build on each change detected.
+
+Configurations
+
+
+
+	output_binary		- output binary artifact inside the runtime container (default: "/app")
+	build_command		- build command inside the runtime container (default: "go build -o {{.output_binary}}")
+	run_command		- run command, probably most of the time will just be the binary artifact path (default: "{.output_binary}}")
+	runtime_image 		- base Docker image for the runtime container (default: "golang:1.14")
+	debugger_enabled 	- whether to enable delve debugger inside the container or just use hot-reload (default: false)
+	debugger_port 		- delve debugger listen port, relevant only if debugger_enabled was set (default: 40000)
+	expose_ports 		- list of ports to expose inside the container (default: [])
+	networks 		- list of docker external networks to join. if no network is selected, a new one will be created (default: [])
+	environment 		- list of environment variables to be set inside the container (default: [])
+
+
+Notes & Tips
+
+	- Note you can reference other configuration fields.
+	- When enabling Debugger -gcflags="all=-N -l" will be appended to the build command to stop compiler optimization and symbol removing.
+	- No need to add the delve debugger listen port as it will be auto-added
+	- Expose ports use the same syntax as docker-compose for mapping between host and container ports (e.g: "8080:8080")
+	- Environment variables syntax: FOO=BAR or just FOO which will take the variable FOO from host and set it with its value
