- * These functions are designed to make life easy for decompressing
- * kernel images, initrd images or any other gzip compressed image,
- * particularly if its useful to decompress part of the image (e.g. to
- * examine headers) before decompressing the remainder.
- *
- * To use:
- *     - declare a gunzip_state structure
- *     - use gunzip_start() to initialize the state, associating it
- *       with a stream of compressed data
- *     - use gunzip_partial(), gunzip_exactly() and gunzip_discard()
- *       in any combination to extract pieces of data from the stream
- *     - Finally use gunzip_finish() to extract the tail of the
- *       compressed stream and wind up zlib
