The KDE translation HOWTO suggests translating .po template files in the
following order: (a) kdelibs (libraries used by most KDE applications),
(b) desktop_kdelibs, and desktop_kde_i18n which relate to the
entries under the main KDE menu, (c) applications in kdebase, and (d)
then, anything else. At present, I am not aware of a glossary for KDE.
