Using Eclipse (Flex Builder 2) with subclipse is very useful,
but not when you add Flex to the equation. Flex will mess up the
.svn folders, which the only way I've gotten to work is to manually
add each of the flex project files / bin folder to the svn:ignore
list, which is a pain in the butt.
What other tools / plugins have you used to manage your flex
applications as they grow?
