In this case, the name of the output file is derived the name of the input file. <br /> <br /> Note that the filenames must not start with a hyphen. Finally, if output_file has no extension, then it is treated as a directory and an &ldquo;open ebook&rdquo; (OEB) consisting of HTML files is written to that directory. These files are the files that would normally have been passed to the output plugin.<br /> <br /> After specifying the input and output file you can customize the conversion by specifying various options. The available options depend on the input and output file types. To get help on them specify the input and output file and then use the -h option.";
