Grace is a very simple debugging/tracing framework written in the Go programming language. It is currently very young and doesn't do much, but does implment loading processes, setting arbitrary callbacks for breakpoints, and more importantly letting you set breakpoints symbolically in the presence of DWARF symbols.
Grace is also an awful example of idiomatic Go code, but that will change eventually.
To build, simply extract it anywhere and run:
GOPATH=`pwd` go build grace.go
./grace
(So far, Linux only)
Check grace.go for basic usage info.
