 22  """Classes that hold units of .po files (pounit) or entire files (pofile). 
 23   
 24  Gettext-style .po (or .pot) files are used in translations for KDE, GNOME and 
 25  many other projects. 
 26   
 27  This uses libgettextpo from the gettext package. Any version before 0.17 will 
 28  at least cause some subtle bugs or may not work at all. Developers might want 
 29  to have a look at gettext-tools/libgettextpo/gettext-po.h from the gettext 
 30  package for the public API of the library.
