What is a LO file?
Compiled Lisp (.LSP) file saved by Interleaf technical publishing software; contains compiled code that can be run within the program; often used for performing common or repetitive commands.
NOTE: Interleaf 6 and later (now QuickSilver) saves compiled Lisp files in the Fast Save format with an .FAS extension.
