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.

-----------
-* Allow tar to create archives with sockets, devices, and other special files
-* Add in a mini insmod, rmmod, lsmod
-* mkfifo
-* dnsdomainname
-* traceroute/nslookup/netstat
-* rdate
-* hwclock
-* killall
-* stty
-* sort/uniq
-* wc
-* tr
-* expr (maybe?) (ash builtin?)
-* login/sulogin/passwd/getty (These are actully now part of tinylogin, which
- I've just started to maintain).
+Possible apps to include some time:
+* group/commonize strings, remove dups (for i18n, l10n)
+
+-----------
+
+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.
+
+-----------------------
+
+Run the following:
+
+ 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.
+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...
+
+-----------------------
+
+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 .
