It uses Makefile.PL if your app hasn't been installed into a site_perl 
tree, and figures things out from the tree structure otherwise. If your 
app hasn't been installed it seems a reasonable assumption that it's a 
development directory and as such will have a Makefile.PL so it *can* be 
installed when you're done with development.

Even if you're not planning to install the app as such, a Makefile.PL is 
still important as somewhere to encode dependencies in the usual way.
