-I checked in a new tool, primarily useful for debugging.  Given a module 
-and a function name, it extracts just the specified function from the 
-module, with a minimum of related cruft (global variables, function 
-prototypes, etc).
-
-This is useful because often something will die (for example SCCP 
-miscompiles one function of a large benchmark), and so you want to just 
-cut the testcase down to the one function that is being a problem.  In 
-this case, 'extract' eliminates all of the extraneous global variables, 
-type information, and functions that aren't necessary, giving you 
-something simpler.
-
-This is just an FYI, because I've found it useful and thought you guys 
-might as well.
