+Read a property file, sort the remainder alphabetically and write their values to 
+a text file, one value per line.
+
+The idea is that this file could be translated and the result could be used to 
+create a new property file with property_inserter.rb
+
+On the command line provide the path to the properties file. E.g.:
+
+	property_stripper.rb '../../all.properties' output_file
+
