# otorp
Recover [Protocol Buffer](https://en.wikipedia.org/wiki/Protocol_Buffers) v2
definitions from a Mach-O binary.
## Usage
```bash
$ npx otorp /path/to/macho/binary # print all discovered defs to stdout
$ npx otorp /path/to/macho/binary out/ # write each discovered def to a file
```
This library and the embedded `otorp` CLI tool make the following assumptions:
- In a serialized `FileDescriptorProto`, the `name` field appears first.
- The name does not exceed 127 bytes in length.
- The name always ends in ".proto".
- There is at least one simple reference to the start of the definition.
## License
Please consult the attached LICENSE file for details. All rights not explicitly
granted by the Apache 2.0 license are reserved by the Original Author.
