+ansi.js
+=========
+### Advanced ANSI formatting tool for Node.js
+
+![](http://f.cl.ly/items/0D3w3d1W443f2z3X361G/Screen%20Shot%202012-01-26%20at%202.18.31%20AM.png)
+
+`ansi.js` is a module for Node.js that provides an easy-to-use API for
+writing ANSI escape codes to `Stream` instances. ANSI escape codes are used to do
+fancy things in a terminal window, like render text in colors, delete characters,
+lines, the entire window, or hide and show the cursor, and lots more!
+
+The code for the example in the screenshot above can be found in the
+`examples/imgcat` directory.
+
+#### Features:
+
+ * 256 color support for the terminal!
+ * Make a beep sound from your terminal!
+ * Works with *any* writable `Stream` instance.
+ * Allows you to move the cursor anywhere on the terminal window.
+ * Allows you to delete existing contents from the terminal window.
+ * Allows you to hide and show the cursor.
+ * Converts CSS color codes and RGB values into ANSI escape codes.
+ * Low-level; you are in control of when escape codes are used, it's not abstracted.
+
+
+Installation
+------------
+
+Install with `npm`:
+
+``` bash
+$ npm install ansi
+```
+
+
+Example
+-------
+
+``` js
+var ansi = require('ansi')
+ , cursor = ansi(process.stdout)
+
+// You can chain your calls forever:
+cursor
+ .red() // Set font color to red
+ .bg.grey() // Set background color to grey
+ .write('Hello World!') // Write 'Hello World!' to stdout
+ .bg.reset() // Reset the bgcolor before writing the trailing \n,
+ // to avoid Terminal glitches
+ .write('\n') // And a final \n to wrap things up
+
+// Rendering modes are persistent:
+cursor.hex('#660000').bold().underline()
+
+// You can use the regular logging functions, text will be green
+console.log('This is blood red, bold text')
+
+// To reset just the foreground color:
+cursor.fg.reset()
+
+console.log('This will still be bold')
+
+// Clean up after yourself!
+cursor.reset()
+```
