#    or - an unpacked source tree of Qt4 in $QT4SOURCEDIR or in the sibling directory (variable Qt4SourceVersion)

#   the aspell sources placed in a sibling directory (variable ASpellSource)
# * for hunspell support:
#   the hunspell sources placed in a sibling directory (variable HunSpellSource)
# * for dictionary deployment (per default thesauri only):
#   - aspell:   the dictionary files of macports (in /opt/local/share/aspell and /opt/local/lib/aspell-0.60)
#   - hunspell: the dictionary files in the sibling directory dictionaries/dicts
#   - mythes:   the data and idx files in the sibling directory dictionaries/thes
