Con‐\nversely,  the  --less-than option may be used to specify less commonality before messages are\nprinted (i.e.  --less-than=2 will only print the unique  messages).   Translations,  comments\nand  extracted  comments  will  be preserved, but only from the first PO file to define them.\nFile positions from all PO files will be cumulated.\n\nMandatory arguments to long options are mandatory for short options too.\n",
