                           which will be used as display string in the
                           Multisite GUI.
  compile LANG         ... Compiles the .po file into a .mo file which can
                           be used by gettext.
  edit    LANG         ... Call update, open .po in editor and compile in one step

 The regular process for translating is:

 1.) Create/update the .po file for the given language
 2.) Edit the .po file
 3.) Compile the .po file to get a .mo file which can be used by gettext

 Locale files are located in: %s
