func GetAbsolutePath

func GetAbsolutePath(bin string) (string, error)

GetAbsolutePath returns the absolute path of the passed binary by resolving it in the path and following symlinks.

func PluginLoader(opts map[string]string) (map[string]interface{}, error)

PluginLoader maps pre-0.9 client driver options to post-0.9 plugin options.


type Config

type Config struct {
