- * gunzip implementation for wikiviewer (c) Frederik M.J.V., 2006.
- * some bug fixes by Adam Gashlin gunzip implementation for busybox
- *
- * Based on GNU gzip v1.2.4 Copyright (C) 1992-1993 Jean-loup Gailly.
- *
- * Originally adjusted for busybox by Sven Rudolph <sr1@inf.tu-dresden.de>
- * based on gzip sources
- *
- * Adjusted further by Erik Andersen <andersen@codepoet.org> to support files as
- *well as stdin/stdout, and to generally behave itself wrt command line
- *handling.
- *
- * General cleanup to better adhere to the style guide and make use of standard
- *busybox functions by Glenn McGrath <bug1@iinet.net.au>
- *
- * read_gz interface + associated hacking by Laurence Anderson
- *
- * Fixed huft_build() so decoding end-of-block code does not grab more bits than
- *necessary (this is required by unzip applet), added inflate_cleanup() to free
- *leaked bytebuffer memory (used in unzip.c), and some minor style guide
- *cleanups by Ed Clark
- *
- * gzip (GNU zip) -- compress files with zip algorithm and 'compress' interface
- *Copyright (C) 1992-1993 Jean-loup Gailly The unzip code was written and put in
- *the public domain by Mark Adler. Portions of the lzw code are derived from the
- *public domain 'compress'
