    The help text says -m depends on the type of archive. Then doesn't say how to specify the archive type. Then has sections for Zip, Gzip, Bzip etc.

    What does this mean:

    {N}={methodid}[;param1]...[paramn]

    What parameters?

    What is a filter?

    What does this mean:

    b{C1}{s{S1}}:{C2}{s{s2}}

    What does output stream refer to? What is a coder? What does binding a stream to a coder mean?

    I started puzzling over this after using the program 7zip fine-tuner, it spits out output like:

    LC: 5
    LP: 0
    PB: 0
    Method: LZMA
    YX: 5
    FB: 187

    How would I specify those options?
