oxford asl 6 : is folder input supported?

[MontrealSergiy]

I see that in the oxford boutiques output file name is defined by the input file.

However what if instead of input file (-i), the input folder (-d) provide? I think the task will fail.

PS. So far
I see two simple workarounds, 1) if folders inputs are not needed, drop the -d option completely. 2) declare two optional output results - one obtained from the input file and another obtained from input folder
