Command-line utility for ELF files with the following features.
- Inspect ELF contents.
- Prints ELF dependencies.
- Patch `RPATH`, `RUNPATH` and program interpreter.
- Relocate ELF files together with their dependencies to a different system
  (this involves patching `RUNPATH` and program interpreter).

Based on [`elb`](https://docs.rs/elb) crate.


## Installation

```sh
cargo install elb-cli
# symlink `elb-cli` to `elb`
ln -s $(which elb-cli) $(dirname $(which elb-cli))/elb
```
