updated docs/busybox.pod accordingly. -beppu
* Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
* Added setkeycodes, for those that have wierd keyboard buttons.
+ * Added cut and tr from minix, since due to the license change,
+ we can now use minix code. Minix tr saves 4k.
* Fix for ping warnings from Sascha Ziemann <szi@aibon.ping.de>
* Fixed update segfault
* Fixed mknod -- minor number was always 0
* added a simple id implementation; doesn't support sup. groups yet
* logname used getlogin(3) which uses utmp. Now it doesn't.
* whoami used getpwuid(3) which uses libc NSS. Now it behaves.
- * Due to the license change, I can now use minix code. Minux tr
- replaces the BSD derived tr, saving 4k and eliminating bsearch(3)
- from the list of used Libc symbols.
* Add support for "noatime" and "nodiratime" mount flags to mount.
* Changed 'umount -f' to mean force, and actually use umount2.
* Changed 'umount -l' to mean "Do not free loop device".
* More doc updates
* cp -fa now works as expected for symlinks (it didn't before)
* zcat now works (wasn't working since option parsing was broken)
+ * Renamed "mnc" to the more correct "nc".
+ * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
+ help messages (i.e --help). Saves 17k over a full compile.
