You can learn everything you would ever wish to know about Gruntz's  
algorithm by reading his 1996 PhD thesis:

http://www.cybertester.com/data/gruntz.pdf

If you want source code, the likelihood is negligible that you will get  
that which is used in Mathematica, although there are open-source CASs  
whose source code you may study. However, I doubt if any of these  
implementations will be particularly simple; in fact, the computer codes  
will probably be more confusing than the formal description of the  
algorithm.
