I meant the absolute dir containing the executable. Thing is I want to throw
a config file in the same dir that will be found regardless of how the thing
got started (from the program dir with ./, from a different dir with
absolute path, with relative path, from cron, etc.). In other words exactly
what you proposed.
Btw looking at the source both you and mine methods end up using the same
core modules. I guess for this there isn't really TIMTOWTDI. OTOH mine
does not pollute namespace and yours is more readable. Counts as more than
one way I guess :)

Thanks
