xlSlim v1.0.2 adds support for specifying additional Python module search paths when importing modules.
Additionally, you can filter which functions are registered in Excel and the names functions are registered under. This is very useful if you are registering a module with many functions and you are only interested in one or two. Often Python function names are not very clear. Now xlSlim lets you register functions with your own names.
See a complete example in the documentation.
