 properties is a Go library for reading and writing properties files.
 
-It supports reading from multiple files and Spring style recursive property
-expansion of expressions like `${key}` to their corresponding value.
-Value expressions can refer to other keys like in `${key}` or to
-environment variables like in `${USER}`.
-Filenames can also contain environment variables like in
-`/home/${USER}/myapp.properties`.

 struct tags.
