dependendancy check

Hey man, I was fiddling a bit with bangsh.
Don't you think it could use a facility which checks if certain applications are installed?
If so, here's a possible attempt :D
I usually check this before my bash apps get busy, bashscripts can rely on many binaries you know.

Hope all is well,

ps. do you have some kind of roadmap for bangsh? Can I also contact you by email concerning bangsh (roadmap)?
