This software is free.
This software is provided "as is". If you have lost a million dollars by using it, that was your million, not mine. I should not be liable for any losses.
Starting from version 0.42, the fsa package can be distributed with a GPL licence except for one third party file that has its own copyright and licence. Since I'm not sure how to understand the legalese gibberish with regard to third party software, GPL is not included in the package.
