 These are the general steps that are followed when doing a SuperPMI collection:
 
 1. Collect .MC files. Set up for collection, then cause the JIT to be invoked
-by either running a scenario, running tests, crossgen compiling assemblies,

 During collection, the data for each JIT compiled function is stored
 in a uniquely named file with a ".MC" filename extension (for "method context").
