 This project (or approach) might be useful in multiprocessing environments
 running many unattended processes. The most common case for me is on
 production web servers that I can't really stop and debug. For each 
-exception caught, I write a small pydump file and I can debug each
-issue on my own time, on my own box (provided the source is located
-in the same place as on the production box).
+exception caught, I write a dump file and I can debug each issue on
