`cli.go` is simple, fast, and fun package for building command line apps in Go. The goal is to enable developers to write fast and distributable command line applications in an expressive way.
## Overview
Command line apps are usually so tiny that there is absolutely no reason why your code should *not* be self-documenting. Things like generating help text and parsing command flags/options should not hinder productivity when writing a command line app.
**This is where cli.go comes into play.** cli.go makes command line programming fun, organized, and expressive!

`PROG=myprogram source /.../cli/autocomplete/bash_autocomplete`
#### To Distribute
Copy `autocomplete/bash_autocomplete` into `/etc/bash_completion.d/` and rename
it to the name of the program you wish to add autocomplete support for (or
automatically install it there if you are distributing a package). Don't forget
to source the file to make it active in the current shell.
```
sudo cp src/bash_autocomplete /etc/bash_completion.d/<myprogram>
source /etc/bash_completion.d/<myprogram>
```
Alternatively, you can just document that users should source the generic
`autocomplete/bash_autocomplete` in their bash configuration with `$PROG` set
to the name of their program (as above).
## Contribution Guidelines
Feel free to put up a pull request to fix a bug or maybe add a feature. I will give it a code review and make sure that it does not break backwards compatibility. If I or any other collaborators agree that it is in line with the vision of the project, we will work with you to get the code into a mergeable state and merge it into the master branch.
