[sane-devel] Option text help

[littlesincanada]

Hi,
While scanning through the messages to fix up some grammar and spelling 
mistakes, I came across this following in the file:

backend/kvs40xx_opt.c:405

There is a message that I cannot decipher:

"Long Paper Mode is a mode that the scanner reads the image after it 
divides long paper by the length which is set in Document Size option."

Can anyone tell me what it means and what it does?

Cheers,
Ralph
