 common config file handling for protobuf defined config files
+intended to be super simple so the code you need to write is simple.
 
-By default, the config files are stored as:
+Enables Load functions:
 
-~/.config/<argname>/<protoname>.text
+// loads ~/.config/myapp/trees.text
+cfg := new(MyPB)
+err := config.ConfigLoad(cfg, "myapp", "trees")
 
-assumes config files are simple, intended to be edited by hand
-by the user and can be exported by protobuf FormatTEXT()
+Enables Save functions:
 
-intended to be called by functions that are automatically
-generated by 'autogenpb' for protobuf defined config files.
+err := cfg.Save() // it automatically knows where to save
 
-If you aren't using .proto defined config files, this package is not for you
