+# encoding: UTF-8

+# The above encoding line is a magic comment to set the default source encoding
+# of this file for the Ruby interpreter.  It must be on the first or second
+# line of the file if an interpreter is in use.  In Ruby 1.9 and later, the
+# source encoding determines the encoding of String and Regexp objects created
+# from this source file.  This explicit encoding is important becuase otherwise
+# Ruby will pick an encoding based on LANG or LC_CTYPE environment variables.
+# These may be different from site to site so it's important for us to
+# establish a consistent behavior.  For more information on M17n please see:
