What is a Ballista?

A Ballista is an ancient military siege engine in the form of a crossbow. Typically it was used to hurl large bolts, and had better accuracy than a catapult at the expense of reduced range.

We chose the name "ballista" for this project because we too are attempting to accurately "hurl projectiles" at software in an attempt to expose robustness failures.

PLEASE NOTE: We don't have anything to do with siege weapon information, plans, construction, or any other related activities. We just used the word "Ballista" as a cool name for a computer software project! So please don't ask us for plans on how to build a siege weapon -- we can't help you with that.
