goupx - Fix Go ELF executables to work with upx
Installation: go get github.com/pwaller/goupx/
(or if you don't want to do it with root, GOPATH=${PWD}/env go get github.com/pwaller/goupx/
will install it to ${PWD}/env/bin/goupx
)
Usage: goupx [filename]

This is only necessary for ELF executables (not Mach-O executables, for example).
Based on code found on the upx bugtracker.
