What is an .EFL file?

Formatting file used by NFBTRANS, a Grade Two braille translation program developed by the National Federation of the Blind (NFB); contains instructions that direct the translator how to process a given input file.

EFL files may be global (used by multiple text files) or specific to a single file. Specific EFL files have the same filename as the text file, i.e. "document1.txt" and "document1.efl."
