you can look them up in a DB - once that is created - or in the wiki 
(again like 5.0), other than that each exception has its unique code and 
thus you can identify which one it is very quick - there will be only 
one place in the source with that specific code.

you can of course say codes X,Y, and Z belong to DB errors, while A,B, 
and C belong to file system errors, and you can always mention (or 
guess) what happened in the error message (first parameter)
