Please clarify examples

[joshuakraemer]

Hello and thank you very much for your work on jbig2enc! I would like to use it to generate PDF files with lossless JBIG2 encoding (generic coder). Could you please clarify the following questions, which are not clear to me referring to the Readme and examples:

• What exactly is "standalone mode"? Is it the generic coder mode?
• If "standalone mode" is generic coder mode, and the "-a" switch means "use automatic thresholding in symbol encoder", why does the example still use the "-a" switch for standalone mode? Does it have any effect in that mode?
• If "standalone mode" isn't generic coder mode, could you please give an example of losslessly encoding page images into a PDF file containing JBIG2 images?
