4456f25e8f Rewrite timescmd() function to avoid the use of floating point and to 
correct a bug in the seconds display where something like  65 seconds
would be output as "1m65.000000s".

e5642119ee Patch from Thomas Cameron: 
Hello all,
	    This patch adds more "Help" text to the config system.  Almost
    all applets now have a help entry.  Also, I cleaned up the spacing of
    the existing text so that things are consistent.  This patch is against
    this morning's CVS.

c9f20d9fb9 Yet another major rework of the BusyBox config system, using the considerably 
modified Kbuild system I put into uClibc.  With this, there should be no more
need to modify Rules.mak since I've moved all the interesting options into the
config system.  I think I've got everything updated, but you never know, I may
have made some mistakes, so watch closely.

350d26bbbb - the number of commands in the history list is now configureable via the 
config system
 - added a new config option to allow persistant history lists. This is
   currently only used by ash, but the calls ({load,save}_history) could
   be added to the other shells as well.

#50: I found bug in loginutils/Makefile.in.
New patch have also new function to libbb and
aplied this to applets and other cosmetic changes.

8e139871fe Patch from Stewart Brodie <stewart.brodie@pace.co.uk> to fix ash: 
When alias support is not configured, ash believes that command parameters
that look like dd's "if=/dev/zero" are requests to set a temporary
environment variable whilst dd is running, even though it appears after the
command name.  This is caused by the re-use of the checkalias global variable
to indicate when both alias checking and environment variable checking.  The
failure to reset this flag is due to the reset action being performed only
inside the feature check CHECK_ASH_ALIAS.  Hence ash works as expected when
aliases are configured in, and fails when not.

Example script using 'date' with different settings of TZ:

# TZ=Europe/London
# export TZ
# date
Thu May 30 17:18:49 BST 2002
# TZ=America/New_York date
Thu May 30 12:19:10 EDT 2002
# date
Thu May 30 17:19:12 BST 2002
# date TZ=America/New_York
Thu May 30 12:19:30 EDT 2002    <----- wrong, should be BST time (or error!)
# date
Thu May 30 17:19:35 BST 2002

Attached is a patch against revision 1.52 of ash.c which moves the checks so
that checkalias is updated regardless of whether CONFIG_ASH_ALIAS is set.
With this patch applied, the command shown above which should generate an
error does generate an error.

I have tested this patch with the 'dd' command too and that now works
correctly.

85208e2ab9 Completely rework the config system so that it no longer annoys me to work on

ec07469a3e Patch from Aaron Lehmann <aaronl@vitelus.com>; 
This diff does 2 things:

    1) removes an unnecessary function. saves 64 bytes on i386

    2) allows you to disable checking of mail (actually, it's now disabled
    by default). this would be a nice CML1 option, but for now it's a
    #(define|undef) in the C file like the other internal ash options.
    this saves an additional 352 bytes if you leave mail disabled.

to know which shell is in use.  Add in 'help' to list available
builtins, and fixup msh so it can do STANDALONE_SHELL.

8df319b213 A bit of testing today showed that ASH_BBAPPS_AS_BUILTINS was 
totally breaking the shell.  Simple thinge like 'FOO=100' caused
it to segfault.  It turns out that disabling "bltincmd" is a very
bad idea.

ff9eee475f This is a busybox port of the Minix shell. It is reasonably capable, 
handles all the basic stuff (for, case/esac, while, if/then/else), and
is very small (adds just 38k on x86).  It is not as rigorously correct
about Bourne semantics as bash, but for most things it is quite
workable.  There is still some work to be done to further shrink it (it
has its own globbing functions instead of using the libc ones, for
example), but it is quite usable as is.

    > I write this special for variable HUSH_VERION=0.01)

    > 6) next add integraion with libbb

Valdimir's patch missed two cases of local variable handling
    FOO=bar
    export FOO=baz
    unset FOO
and
    export FOO=bar
    FOO=baz
which were working before, so I fixed those two cases.

78a7c99f7f This patch covers one big part of variable handling. 
$ a=b foo
should be handled correctly.
$ a=b
is parsed OK, but the actual variable setting is not
yet written.  Except for some weird exceptions related
to quoting rules, this code passes (matches ash behavior)
all the tests I threw at it.

If someone now writes set_local_var(), and updates lookup_param()
to match, we can claim success!

25f2703015 This is the initial checkin of Larry Doolittle's hush.c, using his 
April 25, 2001 snapshot, adjusted a bit by me so it has cmdedit support.

This checkin also removes sh.c.  In the future sh.c will be a symlink to
your shell of choice.  For now, this symlink will default to pointing to
lash.c (as in the past).  If you change the symlink to point to hush.c,
then thats what you will get.  This symlink business is a temporary situation,
which will be cleaned up Real Soon Now(tm).
