* I added a changelog for version 0.30.
* adjusted find internals to make it smaller, and removed
some redundancy.
* Fixed a segfault in ps when /etc/passwd or /etc/group
are absent. Now will warn you and carry on.
* Added in optional _real_ regular expression support (to be
the basis for a future sed utility). When compiled in,
adds 3.9k.

Major changes -- lots of stuff rewritten. Many thanks to Lineo for
paying me to make these updates. If you have any problems with busybox,
or notice any bugs -- please let me know so I can fix it.
or notice any bugs -- please let me know so I can fix it. These
changes include:
Core Changes:
* busybox can now invoke apps in two ways: via symlinks to the
busybox binary, and as 'busybox [function] [arguments]...'
* When invoked as busybox, the list of currently compiled in
functions is printed out (no this is not bloat -- the list
has to be there anyway to map invocation name to function).
* busybox no longer parses command lines for apps or displays their
usage info. Each app gets to handle (or not handle) this for
itself.
* Eliminated monadic, dyadic, descend, block_device, and
postprocess. It was cumbersome to have so many programs
cobbled together in this way. Without them, the app is much
more granular.
* All shared code now lives in utility.c, and is properly
ifdef'ed to be only included for those apps requiring it.
* Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
so now each app has the function prototype of (da-dum):
extern int foo_main(int argc, char** argv);
which speeds integration of new apps.
* Adjusted the Makefile to make it easier to
{en|dis}able debugging.
* Changed default compiler optimization to -Os
(optimize for smaller binaries).
App Changes:
* To cope with the new app function prototype and the removal of
monadic, dyadic, etc, the following apps were re-written:
* cat - Works same as always.
* chgrp, chmod, chown - rewrite. Combined into a single
source file. Absorbed patches from Enrique Zanardi <ezanard@debian.org>
that removes the dependency on libc6 libnss* libraries.
* cp - Can now do 'cp -a' can can copy devices,
pipes, symlinks, as well as recursive or non-recursive dir copies.
* fdflush - adjusted to remove dependancy on struct FileInfo.
* find - Now includes some basic regexp matching
which will be the basic of a future mini-sed.
* ln - Same functionality.
* mkdir - Added -p flag to feature set.
* mv - rewrite.
* rm - Added -f flag to feature set.
* rmdir - Same functionality.
* swapon, swapoff - Combined into a single binary. No longer
uses /etc/swaps. swap{on|off} -a uses /etc/fstab instead.
* touch - Same functionality.
* date - adjusted with a patch from Matthew Grant <grantma@anathoth.gen.nz>
to accomodate glibc timezone support. I then ripped out GNU getopt.
* mkswap -- new version merged from util-linux. Can now make >128Meg swaps.
* Replaced the old and star, unstar, and tarcat with the tar
implementation from sash. Now tar behaves as god intended
it to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
* dd -- rewritten. Can with with files, stdin, stdout.
* Added the following new apps:
* loadfont -- added from debian boot floppies
* chroot -- added based on a patch from Paolo Molaro <lupus@lettere.unipd.it>
* grep -- I just wrote it. Only matches simple strings
* ps -- I just wrote it. Has _no_ options at all, but works.
* fsck_minix, mkfs_minix -- added from util-linux, but I ripped out
internationalization and such to make them smaller.
* sfdisk -- Added from util-linux (minus internationalization and such).
* Probably some other changes that I forgot to document...
