# NOTES:
# english language files are always installed because they are used by default
#   that is a tesseract bug and if possible this workaround should be avoided
#   see bug 287373
# deu-f corresponds to an old german graphic style named fraktur
#   that's the same language (german, de)
# stuff in directory java/ seems useless...
# in testing/, there is a way to test accuracy, not usable for src_test()
# app-ocr/ would be a better category
