| // pretty/useful). |

| // BusyBox will, by default, malloc space for its buffers. This costs code |
| // size for the call to xmalloc. You can use the following feature to have |
| // them put on the stack. For some very small machines with limited stack |
| // space, this can be deadly. For most folks, this works just fine... |
| //#define BB_FEATURE_BUFFERS_GO_ON_STACK |
| // The third alternative for buffer allocation is to use BSS. This works |
| // beautifully for computers with a real MMU (and OS support), but wastes |
| // runtime RAM for uCLinux. This behavior was the only one available for |
| // BusyBox versions 0.48 and earlier. |
| //#define BB_FEATURE_BUFFERS_GO_IN_BSS |
| // |
| // Turn this on to use Erik's very cool devps, and devmtab kernel drivers, |

| // feature, you _must_ have patched the kernel to include the devps patch that |
| // is included in the busybox/kernel-patches directory. You will also need to |
| // create some device special files in /dev on your embedded system: |

| #define BB_FEATURE_SH_STANDALONE_SHELL |
| // |
| //When this is enabled, busybox shell applets can be called using full path |
