+This is a port of a python module used for finding what directory you 'should'
+be using for saving your application data such as configuration, cache files or
+other files.
+
+The location of these directories is often hard to get right. The original python
+module set out to change this into a simple API that returns you the exact
+directory you need. This is a port of it to Go.
+
+Depending on platform, this package exports you at the least 6 functions that
+return various system directories. And one helper struct type that combines the
+functions into methods for less arguments in your code.
+
+Each function defined accepts a number of arguments, each argument is optional
+and can be left to the types default value if omitted. Often the function will
+ignore arguments if the name given is empty.
+
+Passing in all default values into any of the functions will return you the base
+directory without any of the arguments appended to it.
