| Store bbconfig data in compressed form, uncompress them on-the-fly |
| before output. |
| |
| If you have a really tiny busybox with few applets enabled (and |
| bunzip2 isn't one of them), the overhead of the decompressor might |
| be noticeable. Also, if you run executables directly from ROM |
| and have very little memory, this might not be a win. Otherwise, |
| you probably want this. |

| When enabled expect strings which are started with a dash trigger |
| no-fail mode. That is when expectation is not met within timeout |
| the script is not terminated but sends next SEND string and waits |

| or executables before they are used. When used at the right time |
| (in particular when a CPU bound process is running) it can |
