Contrib

# Contrib
Contrib libraries, or widget types, are extra snippets of code you can
use. Some are for less common hardware, and other were contributed by
Vicious users. The contrib directory also holds widget types that were
obsoleted or rewritten. Contrib widgets will not be imported by init
unless you explicitly enable it, or load them in your rc.lua.
## Usage within Awesome
Usage within Awesome
--------------------
To use contrib widgets uncomment the line that loads them in
init.lua. Or you can load them in your rc.lua after you require
Vicious:
```lua
vicious = require("vicious")
local vicious = require("vicious")
vicious.contrib = require("vicious.contrib")
```

argument given to vicious.register as the first argument, `warg` as
the second, and return a table of values to insert in the format
