13    stream is provided on the command line.  The compressed stream is decoded in
15    in the uncompressed output.  The compressed file is left open, and can then
23    point in the uncompressed stream.  build_index() works by decompressing the
26    a new access point.  If so, that point is saved in a data structure that
29    To use the index, an offset in the uncompressed data is provided, for which
30    the latest accees point at or preceding that offset is located in the index.
31    The input file is positioned to the specified location in the index, and if
34    the decompression then proceeds until the desired offset in the file is
51    use of pointers in the state.  The approach here allows for storage of the
52    index in a file.
