| | | | | | | | | | | | | 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. -Erik git-svn-id: svn://busybox.net/trunk/busybox@2949 69ca8d6d-28ef-0310-b511-8ec308f3f277
