It's for cases where you want to mark a string to be included in the
language files, but you don't want to change the string by doing the
translation immediately. An example would be a string used as a key in
an untranslated data file that later needs to be translated for output.
The N_() function applied to the string literal would just mark it, then
the _() function could be applied later to a variable containing that
Note that you will also need to slightly modify the pylupdate program
to look for the _() and N_() functions and to use the proper context.

This method still works with py2exe, but I don't know about other freeze
