[Dancer-users] Can't override appdir on import?

Messing around with my first dancer app, so I'm a newbie. I'm using a non-standard layout (I want my dancer app in the 'bin' subdirectory, as it's only a small part of a bigger picture), but I can't find a way to override appdir at Dancer::import time? I can set it post-import via 'set appdir => X', and that works for most things, but it doesn't at least for logging, where logdir is set from appdir at import time (to the default). Is there a way of overriding this at import time? If not, should there be? Is a DANCER_APPDIR environment variable an option? Cheers, Gavin
