Subject
Update the TODO list to reflect stuff we've already done.
SOURCE BUG
This commit was genuinely broken at the time (not related to our build system): scripts/config/mkconfigs.c (2005-08-01 - 2006-10-05 arasi) uretilen bbconfigopts.h icine .config satirlarini kacissiz, ham newline'larla gömüyordu - gecerli C degildi, busybox'un kendi bb_mkdep araci bile parse edemiyordu (7d219aab7 ile duzeltildi, mkconfigs shell scripte cevrildi)

| + | Busybox 1.1 will be capable of replacing most gnu packages for real world use, |
| + | such as developing software or in a live CD. It needs wider testing. |
| + | |
| + | Busybox should now be able to replace bzip2, coreutils, e2fsprogs, file, |
| + | findutils, gawk, grep, inetutils, less, modutils, net-tools, patch, procps, |
| + | sed, shadow, sysklogd, sysvinit, tar, util-linux, and vim. The resulting |
| + | system should be self-hosting (I.E. able to rebuild itself from source code). |
| + | This means it would need (at least) binutils, gcc, and make, or equivalents. |
| It would be a good "eating our own dogfood" test if buildroot had the option | |
| - | of using busybox instead of bzip2, coreutils, file, findutils, gawk, grep, |
| - | inetutils, modutils, net-tools, procps, sed, shadow, sysklogd, sysvinit, tar, |
| - | util-linux, and vim. Anything that's wrong with the resulting system, we |
| - | can fix. (It would be nice to be able to upgrade busybox to be able to |
