TODO list for busybox in no particular order. Just because something
is listed here doesn't mean that it is going to be added to busybox,
-or that doing so is even a good idea. It just means that I _might_ get
-around to it some time. If you have any good ideas, please let me know.
-
-* login/sulogin/passwd/getty/etc are part of tinylogin, and so are not
- needed or wanted in busybox (or else I'd have to link to libcrypt).
-
-* We _were_ going to split networking apps into a new package called
- netkit-tiny. Per discussions on the mailing list, this isn't going
- to happen. False alarm. Sorry about the confusion.
-
-* The busybox shell, lash, is really too weak for serious use, although it is
- possible to run many simple systems with it. BusyBox 0.49 was supposed to
- have a new shell, updated to understand full Bourne grammar. Well, that
- simply didn't happen in time for the release. A rewrite is in progress
- that will result in a new shell that understands the full Bourne grammar.
- This new shell is being championed by Larry Doolittle
- <ldoolitt@recycle.lbl.gov>, and could use your help. Please see the work
- in progress at http://doolittle.faludi.com/~larry/parser.html and help
- us out.

Possible apps to include some time:
-* hwclock
* group/commonize strings, remove dups (for i18n, l10n)
-----------
-Write a fixup_globals function to do just that right before calling
-non-forking applets. Or, just always fork in the shell...
+With sysvinit, reboot, poweroff and halt all used a named pipe,
+/dev/initctl, to communicate with the init process. Busybox
+currently uses signals to communicate with init. This makes
+busybox incompatible with sysvinit. We should probably use
+a named pipe as well so we can be compatible.

rm -f busybox && make LDFLAGS+=-nostdlib 2>&1 | \
sed -ne 's/.*undefined reference to `\(.*\)..*/\1/gp' | sort | uniq
-reveals the list of all external (i.e. libc) things that BusyBox depends on.
+reveals the list of all external (i.e., libc) things that BusyBox depends on.
It would be a very nice thing to reduce this list to an absolute minimum, to
reduce the footprint of busybox, especially when staticly linking with
libraries such as uClibc.
Compile with debugging on, run 'nm --size-sort ./busybox'
and then start with the biggest things and make them smaller...

- du.c probably ought to have an -x switch like GNU du does...

xargs could use a -l option

+libbb/unzip.c and archival/gzip.c have common constant static arrays and
+code for initializing the CRC array. Both use CRC-32 and could use
+common code for CRC calculation. Within archival/gzip.c, the CRC
+array should be malloc-ed as it is in libbb/unzip.c .
