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

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

```bash
L=/usr/local/bin/tldr  # elevated privileges needed for some locations
sudo wget -qO $L good4.eu/tldr
sudo chmod +x $L
```

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

## Autocompletion
When the following lines are added to `~/.bashrc` or run in the current session,
then *tldr* will autocomplete, which means possible tldr page names will be
suggested when tapping the **Tab** key twice on an incomplete tldr page name:
```
cachedir=~/.local/share/tldr/pages # Or whatever else the location of the tldr cache is
complete -W "$(q=($cachedir/*/*); sed 's@\.md @ @g' <<<${q[@]##*/})" tldr
```
