+# FILE: dump.sh
+# USAGE: dump.sh [-i interface] [tcpdump-parameters]
+# DESCRIPTION: tcpdump on any interface and add the prefix [Interace:xy] in front of the dump data.
+# OPTIONS: same as tcpdump
+# REQUIREMENTS: tcpdump, sed, ifconfig, kill, awk, grep, posix regex matching
+# BUGS:  ---
+# FIXED: - In 1.0 The parameter -w would not work without -i parameter as multiple tcpdumps are started.
+#        - In 1.1 VLAN's would not be shown if a single interface was dumped.
+# NOTES: ---
+#        - 1.2 git initial
