## Usage
| Argument | Description |
| ---------------- | ---------------------------------------------------- |
| `-r`, `--root` | Perform zone transfer on root nameservers. |
| `-t`, `--tld` | Perform zone transfer on a specific TLD. |
| `-ts`, `--tlds` | Perform zone transfer on all TLDs. |
| `-o`, `--output` | Specify the output directory *(default is axfrout)*. |
| Argument | Description |
| --------------------- | ---------------------------------------------------- |
| `-c`, `--concurrency` | Maximum concurrent tasks. |
| `-o`, `--output` | Specify the output directory *(default is axfrout)*. |
| `-t`, `--timeout` | DNS timeout *(default: 30)* |
## Information
I only wrote this to shit on **[this bozo](https://github.com/flotwig/TLDR-2/tree/main)** who took a dead project & brought it back to life by making it even worse. Rather than making a pull request to give this bloke more credit in his "tenure" as a developer, I decided to just rewrite it all from scratch so people can fork off of *clean* code instead.
