There IS a way to do it, because the ANT utility can take a chmod parameter
from the build.xml file and create the files with the specific permissions
you need. The source code for ANT is at jakarta.apache.org/ant and you can
look for the specific method that does this. Actually, if you find it, post
it here - it would be a really useful bean!
Cheers!
