How to test my changes to tramp on Mac OS ?

[Justin Joseph Kaipada]

Hello emacs--people,

At work I need to mess with files in Z/OS aka OS 390, since it is unix compliant OS, I thought I can connect to it with tramp. I am not sure how I can test anything I write. I got tramp source from savannah. If I change a file, how to test my changes ? I am seeing many tramp files in  /Applications/Emacs.app/Contents/Resources/lisp/net/ with .gz extension, will changing this file directly and restarting emacs enable me to load this file ? My knowledge on lisp is only beginner level, I have tone of time in my hands thou.

Thanks
