`q.sh` is a command-line tool that allows you to interact with your
computer using natural language.
Example usage:
```sh
export Q_SCRIPT_DIR=`pwd`
./q 2.0 kg in pounds
4.41
./q 1 pounds in kg
0.45
./q random number 1-100
53
```
## Extending q.sh
You can extend `q.sh` using any programming language. In order to do so, you
need to place an executable file starting with `q-` in `Q_SCRIPT_DIR`
(by default, ~/.config/q.sh).
When called without parameters, your script should return a newline-separated
list of regular expressions that match strings it's interested in.
When called with an argument, this argument will always be what it expects to
get as input. `q.sh` will take care of dispatching the calls properly.
To get an idea how it works, you can stury `q-weight-convert` and `q-random-number`
that are located in this repository.
To see an example of how to write a `q.sh` extension, take a look at `q-bookmarks`.
