l3x

# What I want is a Rails or Merb plugin that:
#
# * Prints "START" at the start and "END" at the end of each method.
# * That only requires me to enter acts_as_traceable in the class that I want to trace
#
# Output should look something like this:
#
# *** START myclass.mymethod ***
# processing...
# ***  myclass.mymethod  ***

// GetIPv4Address returns this node's IPv4 IP Address
// If more than one IP address found, call GetPreferredOutboundIP
// 127.0.0.1 will be returned if no other IPv4 addresses are found;
// otherwise, the non 127.0.0.1 address will be returned
// Assumes node has at least one interface (and the 127.0.0.1 address)
// If any errors occur, 127.0.0.1 will be returned
func getIPv4Address() (net.IP, error) {
