The Automatic .Lit extractor runs ConvertLIT to explode (DRM-free) LIT to OEB (HTML with an OPF file). This can then be read directly by FBReader.
If you instead run ConvertLIT on a PC, then there are two good options: a) zip all the resulting files and rename the .zip to .oebzip, or b) use mobigen.exe to convert to a MOBI file. FBReader will read an OEBZIP file, and both FBReader and the MobiPocket Reader will read a MOBI file. The mobigen.exe command should have the form:
Code:
mobigen.exe file.opf -c1 -s0 -jpeg
