+       help
+         If this is defined, the environment variable tftpsrcp is used to
+         supply the TFTP UDP source port value.  If tftpsrcp isn't defined,
+         the normal pseudo-random port number generator is used.
+
+         Also, the environment variable tftpdstp is used to supply the TFTP
+         UDP destination port value.  If tftpdstp isn't defined, the normal
+         port 69 is used.
+
+         The purpose for tftpsrcp is to allow a TFTP server to blindly start
+         the TFTP transfer using the pre-configured target IP address and UDP
+         port. This has the effect of "punching through" the (Windows XP)
+         firewall, allowing the remainder of the TFTP transfer to proceed
