A further follow up on the grammar download from the FS Mod pocketsphinx wiki page.

The contents of these 4 folders .lm files, pizza_crust, pizza_size, pizza_specialty, pizza_toppings, is empty but what lmtool generates is found in these folders .sent.arpabo files.

On the other hand, the remaining folders, pizza_arso, pizza_order, pizza_type, pizza_yesno, have content in their .lm files but nothing inside their .sent.arpabo files.

It seems that .lm files are needed, but What are these .sent.arpabo files and are they needed?
