Gujin is a GPL bootloader (homepage http://gujin.org) which can not only load the standard vmlinuz file format but also a simpler format, called Gujin native format, filename using the extension *.kgz. It is simply the standard ELF executable file vmlinux translated to binary image by OBJCOPY and compressed by GZIP. The GZIP format (rfc1952) define a way to add a comment to the GZIP file, it is used extensively to add information to the kernel, like the loading and running address, the processors supported, the 4 Kb memory parameter address, the text/video modes accepted at startup. This comment string is unlimited (finishes at the next '\0'). Unfortunately there isn't any tools around to display or manipulate this field, vi/emacs would work but are not the best tools. So this patch create a file script/gzcopy.c and Makefile rules to produce script/gzcopy which can be use to view, change (set/append/prepend) comment to GZIP files. Type "./script/gzcopy --help" for a list of switches. This first file (and only this one) is released under a BSD license to enable anybody else to add it in a "GZIP distribution" if needed, it follow special rules for indentation and a special way to define strings so that localisation should be simpler. This patch also contains the simple script/gzparam.c file and its Makefile rules - that is a simple standalone program to display a text line on stdout containing the base pattern to generate the GZIP comment itself for this configured kernel. It extract the Linux configuration using file ../include/linux/autoconf.h because that seems to be the easiest way when compilation time is not a problem. Just type "make script/gzparam && ./script/gzparam" to see the line produced after the kernel configuration.
