This is a implementation of realpath() function in Go (golang).
If you provide it with a valid relative path / alias path, it will return you with a string of its real absolute path in the system.
The original version is created by Taru Karttunen in golang-nuts group. You may read the original post about it.
go get github.com/yookoala/realpath
import "github.com/yookoala/realpath"
