     .SYNOPSIS
         Uses a module.
     .DESCRIPTION
-        Uses a module.  
-        
-        This can either:
-        
-        * If present, run a module's `Use` function, method, or script property.
-        * Otherwise, run a script block in the module's context.
-        
-        * Run a module's `Use` function, if present
-        * Call a module's `Use` method, if present
-
-        In all cases, the script block should be run in the module's context, using dot-sourcing.
+        Uses a module's context to run a `[ScriptBlock]` (with dot-sourcing).
