+#Nato converter
+
+Convert list of character to the equivalent in NATO alphabet. And it takes care
+of the capitals:
+
+	$ ./nato_converter.py abc
+	aBc: alpha BRAVO charlie
+
+This is useful to give password orally and avoid confusion:
+
+	$ ./nato_converter.py $( pwgen 8 1)
+	Mahngi8i: MIKE alpha hotel november golf india 8 india
+
+If you don't specify an argument, it reads stdint:
+
+	$ pwgen 3 2 | ./nato_converter.py
+	Ym2 0Ge : YANKEE mike 2  0 GOLF echo
