As a command line utility, perhaps?
Something like $ tsdoc p1 p2 ... pN, p being a file path or a pattern.
For example: $ tsdoc server.cs scripts/*.cs
Or perhaps specifying a folder ($ tsdoc Script_HelloWorld) would create a multi-file HTML documentation of all the .cs files found in it, optionally going through child folders (with something like a -r/--recursive flag).
