+# This script is a simple wrapper which prefixes each i3status line with custom
+# information. It is a python reimplementation of:
+# http://code.stapelberg.de/git/i3status/tree/contrib/wrapper.pl
+#
+# To use it, ensure your ~/.i3status.conf contains this line:
+#     output_format = "i3bar"
+# in the 'general' section.
+# Then, in your ~/.i3/config, use:
+#     status_command i3status | ~/i3status/contrib/wrapper.py
+# In the 'bar' section.
+#
+# In its current version it will display the cpu frequency governor, but you
+# are free to change it to display whatever you like, see the comment in the
+# source code below.
