手机嵌入式Linux下可用的busybox源码

	For this release I have bumped the version number to 0.60.0.  This
	reflects the fact that this release is intended to form a new stable
	BusyBox release series.  If you need to rely on a stable version of
	BusyBox, you should plan on using the stable 0.60.x series.  If bugs
	show up then I will release 0.60.1, then 0.60.2, etc...  This is also
	intended to deal with the fact that the BusyBox build system will be
	getting a major overhaul for the next release and I don't want that to
	break products that people are shipping.  To avoid that, the new build
	system will be released as part of a new BusyBox development series
	that will have some not-yet-decided-on odd version number.  Once things
	stabablize and the new build system is working for everyone, then I
	will release that as a new stable release series. 

    Critical Bugfixes:
	* Matt Kraai 
	    -- Fixed wget output file opening (wget failed in 0.52).
	    -- Fixed a memory leak in syslogd (found by Adam Slattery).
	* Vladimir Oleynik, Matt Kraai, Erik Andersen
	    -- several nasty bugs in ash and msh.  msh could not assign
		any variables and had debug code still enabled.  ash
		had several compile errors (depending on selected options)
		and variable assignment problems as well.

    New Applets:
	* David McCullough <[e-mail]> -- modprobe
	* Vladimir Oleynik -- traceroute
	* Erik Andersen -- pidof

    New Scripts:
	* David Schleef, Erik Andersen, Stuart Hughes -- depmod.pl
	    This is a replacement for the depmod program from the modutils 
	    package, but is fully cross platform and is designed to run on 
	    your host system (not on the target).

    Other Changes:
	* Erik Andersen 
	    -- fixed busybox.spec so it should now work on redhat systems
	    -- fixed dos2unix and unix2dos so they should work once again
	    -- Adjustments to make busybox more uClinux friendly.  Busybox
		should now work on uClinux systems without needing and source
		code changes (applets that won't work on uClinux systems are 
		now automagicaly disabled).
	    -- various things (cleanups, libc compatibility work, etc, etc)
	* Jim Gleason <[e-mail]>
	    -- Fixed for sed, where it failed to preserve whether or not the 
		line was previously altered when running a subst command.
	* Matt Kraai 
	    -- Made tar read 20 512byte blocks at a time (like GNU tar)
	    -- Allow msh.c assignments with the export and readonly commands.
	    -- Added BB_FEATURE_DEVFS to enable devfs device names.
	    -- Better devfs support
	    -- Don't save/restore vi readonly flag if vi is compiled read-only.
	    -- Reworked rdate option handling (is now smaller).
	    -- Size reduction in ping
	    -- Always write dd counts to stderr
	    -- Allow multiple shells to be enabled
	* Aaron Lehmann 
	    -- slimmed down md5sum 
	    -- contributed a nice new (hand written, not lex/yacc) Posix math 
		support for ash, which is once again a full posix shell.
	* Felix von Leitner <[e-mail]> -- patches to make busybox 
	    work with dietlibc.
	* David McCullough
	    -- Adjustments to make busybox more uClinux friendly
	* Glenn McGrath 
	    -- Fixed gzip so when a filename is '-' it will use stdin/stdout
	    -- dpkg rewrite.  Should now be compatable with the real dpkg, 
		but needs more testing.
	    -- Updates to archiving tools (gunzip/gzip/cpio/ar/etc) 
	    -- Rewrote uuencode, will allow base64 encoding to be used by wget
	* Vladimir Oleynik 
	    -- Fixed tr to support 'tr a-z A-Z' syntax,
	    -- Many ash corrections, optimizations, and cleanups.
	    -- optimizations for traceroute, md5sum, chown, ping
	    -- cmdedit updates and API change
	    -- Namespace cleanup (i.e. adding 'static' private function calls)
	    -- added "stopped jobs" warning to ash on exit
	* Adam Slattery
	    -- Fixed ping compile problem
	* Robert J. Osborne <[e-mail]>
	    -- fixed a vi bug with delete and escape sequences on empty files.


	 -Erik Andersen, 31 July 2001



0.52
	
    Critical Bugfixes:
	* Glenn McGrath -- Fixed gunzip, zcat when reading from stdin
	* Marc Karasek and Kanoj (kernel serial.c maintainer) -- fixed init
	    problem on serial consoles with 2.4.3+ kernels.
	
    New Applets:
	* Laurence Anderson -- rpm2cpio applet, this obsoletes rpmunpack 
	    which has now been removed from BusyBox 
	* Laurence Anderson and Glenn McGrath -- cpio applet, currently 
	    only supports unpacking the ascii cpio format.
	* Vladimir Oleynik and Erik Andersen -- added ash, the most correct
	    busybox shell.
	* Larry Doolittle -- hush, small shell designed specifically
	    for busybox.  Quite usable but still a work in progress.
	* Erik Andersen -- msh, minix shell.  A very small but capable shell
	    that only uses vfork, so it can be used on uClinux systems.

    Other Changes:
    	* Sterling Huxley -- Several bugfixes for the vi applet.
	* Glenn McGrath -- Restructure unarchiving code to make more code
	    common to the ar, cpio, dpkg, dpkg-deb applets.
	    tar applet has not yet been assimilated...
	* Matt Kraai -- Rewrote cp, dirname, mkdir, mv, and rm.
	* Paul J.Y. Lahaie <[e-mail]> -- Fixed an endian-ness
	    bug in md5sum (in 0.51, md5sum on big endian machines was broken)

	* Erik Andersen -- bunches of insmod fixes.  It should now always 
	    work (no more segfault or missing symbols problems).
	* Bernhard Kuhn <[e-mail]> and Jinux Kim
	    added uClinux/m68k insmod support.
	* Manuel Novoa III -- rewrote make_human_readable so ls, du, and df
	    should work as expected.  Eliminated use of floats.
	* Aaron Lehmann <[e-mail]> -- Scrubbed gzip.c
	* Alan Modra <[e-mail]> -- fixed an hard to spot
	    bug breaking gunzip checksum checking.

0.51
    Critical Bugfixes:
	* Erik Andersen -- Fixed a bug that could crash the shell in 0.50
	    when pressing <Enter> on an empty line.
	* Gennady Feldman -- Fixed a bug that could crash the shell in 0.50
	    when performing an 'export' in the shell.
	* Gennady Feldman -- fixed a syslogd bug where syslogd could cause
	    the init process to block (which can break systems badly).

    New Applets:
	* Sterling Huxley -- contributed a new vi applet!  This is a very
	    functional vi implementation in Only 22k.
	* Erik Andersen -- added env applet
	
    Other changes:
	* Erik Andersen -- Split utility.c into libbb, which provides a
	    much cleaner was for us to include shared functionality.
	* Erik Andersen -- Reorganized how and when busybox includes 
	    syscalls, aiding portability and (in this case) making the
	    busybox work on ia64 systems.

	    support and added chunked encoding so it is now RFC compliant.
	* John Beppu -- The busybox.pod documentation is now automagically
	    generated from the source code.  This makes it _much_ simpler.  
	    Now to update the docs, just update the usage message...
	* Dirk Behme <[e-mail]> -- Adjusted MIPS insmod 
	    support a bit for Mips RS3.

	    kernel command line environment variables into child environment
	    for init.c

	* Pierre Peiffer <[e-mail]> -- made
		find_pid_by_name() cope with swapped out processes.
	* Jari Ruusu <[e-mail]> -- updates so that setting
	    D_FILE_OFFSET_BITS=64 now works as expected. 
	* Anthony Towns <[e-mail]> -- fixed a bug with 
	    sed address range handling
	* Dmitry Zakharov <[e-mail]> -- a number of updates
	    to wget: support for ftp downloads, basic HTTP basic auth, handling
	    of http redirects, when attempting to continue an aborted download
	    but server doesn't support restarts then reopen output file in
	    write mode, bugfix: when content-length not given, wget didn't
	    download anything, if -c is not specified, it no longer default to
	    restarting an aborted download.
