# Az atnevezeshez hasznalt konfig fajl-t a NAMING_CONF_FILE valtozoban kell beallitani
# A konfig fajlt szerkezeti kriteriumai:
# - A NUM oszlopba, changer definicio eseten "LIB"-et kell irni!
# - A PREFIX hossza + NUM hossza + 4 <= 15 karakter
# - Kommentelni #-tel lehet
# - Az oszlopok tartalma (peldaval):
