[Soot-list] How to add transformation without modifying the Soot source code

[Chris Pickett]

Hi Mario,

Check out the Soot tutorials:

http://www.sable.mcgill.ca/soot/tutorial/

I think you want to look at the source code for:

http://www.sable.mcgill.ca/soot/tutorial/profiler/index.html

in particular.  Let us know if the documentation needs fixing, of course...
