为samsung2410 ARM移植的busybox工具包

	    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.
	* Erik Andersen -- dpkg.c cleanup to use the updated gunzip interface.
	* Erik Andersen -- Cleanups for libc5, glibc, and uClibc.
	* Erik Andersen and Matt Kraai -- Cleanups for the human-readable
	    output from ls, du, and df.
	* Laurence Anderson <[e-mail]> -- Fixed wget HTTP 1.1
	    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.
	* Christophe Boyanique -- egrep invoked the "init" applet in 0.50!
	* Larry Doolittle -- Added -Wshadow and fixed a number of shadowed
	    variables
	* David Douthitt -- fixed 'find -print' 
	* Gennady Feldman -- fixes for the syslogd circular buffer code 
	* Jeff Garzik -- a number of structural cleanups, fixes for -Wshadow 
	    bugs, and similar problems.
	* Matt Kraai -- Added a new 'shutdown' action to busybox init.  Now
	    you can specify arbitrary behavior for 'ctrlaltdel' so now
	    pressing CTL-ALT-DEL can do something else (or nothing).
	* Andreas Neuhaus <[e-mail]> -- fix for merging
	    kernel command line environment variables into child environment
	    for init.c
	* Glenn McGrath -- Fixed problems with dpkg and dpkg-deb applets
	* Glenn McGrath -- Don't try to automount devfs 
	* Vladimir Oleynik -- optimizations for more.c
	* Vladimir Oleynik -- Added locale support to the shell, and fixed
	    locale support in several other places
	* Vladimir Oleynik -- moved struct applet from busybox.c to applets.c
	* Vladimir Oleynik -- A size optimization for rdate
	* Vladimir Oleynik -- Fixed printf applets's locale handling
	* Vladimir Oleynik -- More cmdedit updates
	* Vladimir Oleynik -- Fixed `du' applet so it continues running 
	    after permission errors.
	* Vladimir Oleynik -- Reduced stack usage in recursive_action()
	* 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.
