Classes that hold units of .po files (pounit) or entire files 
  (pofile).
  Gettext-style .po (or .pot) files are used in translations for KDE, 
  GNOME and many other projects.
  This uses libgettextpo from the gettext package. Any version before 
  0.17 will at least cause some subtle bugs or may not work at all. 
  Developers might want to have a look at 
  gettext-tools/libgettextpo/gettext-po.h from the gettext package for the 
  public API of the library.
