General ⇒ How to expand / undefine macros automatically?

[sv75]

Is there any tool or script to expand or undefine all macros defined in my latex document? I would like to have tool to add add '\let\SomeMacro\undefined' for all macros I have defined earlier. Expanding them should be even better. Some editors dislike author-define macros.

I could write python script myself but I wanna use a standart tool. I'm using TeXLive, GNU/Linux and Makefile.
