[Pythonmac-SIG] py2app Enforces Directory Structure?

Hi Bob,

Wow -- that was fast!

Thanks...I wasn't aware of that.

Brilliant!  I was hoping there might be some way of getting this working...

I agree that this isn't something worth arguing about (and I wouldn't
expect you to help me do it, either!), but I just have one comment on
this issue: in the system I'm porting to the Mac, the "data" might
consist of 300+ megabytes of information held in an embedded SQLite
database, along with hundreds of configuration files and
dynamically-loaded Python modules (downloaded automatically from a web
site as they are required).  Our system is pretty darned complicated,
and while I agree that it's not the Mac way of doing things, the
architecture works well and our users really don't care much about the
internal organisation.  This isn't an application designed for mass
distribution, so issues like this really aren't all that important to
us.

Anyway, topic closed.  I certainly don't want to get into an argument
about this...

Thanks for the great (and speedy) help!
