No need to replace anything in the file. Create a file "printdefs.ltx", 
something like this:

% - - - - - printdefs.ltx - - - - -



\noindent Definitions in {\tt\mydefsfile}:

% redefine \def and \newcommand; note that we don't handle parameters!
\def\def#1#2{{\let\def=\Def \noindent {\tt\string #1} : #2\par}}

% lots of standard LaTeX macros will break now,
% so we go for more primitive methods...
\csname @@input\endcsname \mydefsfile

% need to restore this before \end{document}

% - - - - - end of file - - - - -

Change the filename defined at the beginning, of course. Run this 
through LaTeX, and you should get a listing.

One warning: this won't work for definitions of commands with 
parameters; that would take quite a bit more effort, I'd think.
