Open multiple instances of flex builder on OSX

I keep various workspaces in Flex Builder for things like client projects, tests, examples etc. Sometimes it's a pain to have to restart FB just to check something from one workspace, so to be able to have two (or more) workspaces open at a time you can launch multiple instances of flex builder by doing the following:

cd /Applications/Eclipse [or your path to flex builder folder]

./eclipse &
