This client can render both the old and the new tldr markup format.

## Installation
Download the tldr bash script to the install location:

```bash
location=/usr/local/bin/tldr  # elevated privileges needed for some locations
sudo wget -qO $location https://4e4.win/tldr
sudo chmod +x $location
```

If the location is not in $PATH, you need to specify the path to run it.

Alternately, you can do `sudo bpkg-install pepa65/tldr` if you have
[bpkg](https://github.com/bpkg/bpkg) installed.
