## Installation
```
-make all && sudo make install
+./configure && make all && sudo make install
```
-To set the installation directory, use e.g. `sudo make install PREFIX=/usr`.
-
-BZip3 depends on POSIX APIs and the `libc`. All other dependencies (e.g. `libsais`) have been bundled into the source code trunk.
-
-
## TODO
- Avoid a memory copy in `bz3_encode_block`/`bz3_decode_block`.
