+css-tokenize
+============
+
+Coarsely tokenize a stream of CSS, largely modeled after 
+[substack/html-tokenize](/substack/html-tokenize).
+
+```javascript
+var tokenize = require('css-tokenize'),
+through = require('through2');
+
+process.stdin
+.pipe(tokenize())
+.pipe(through.obj(function(token, enc, next) {
+  token[1] = token[1].toString(); // it's a buffer slice
+  console.log('TOKEN', token);
+  next();
+}))
+```
+
+Input:
+```css
+
+div {
+  background: red;
+}
+
+.cls {
+  color: green;
+}
+
+#id {
+  font-size: 10px;
+}
+
+/* comment */
+
+@media screen and (min-width: 1000px) {
+  a {
+    text-decoration: underline;
+  }
+}
+
+a:hover {
+  font-weight: bold;  
+}
+
+section 
+
+
+{
+  margin: 0;
+  /* comment wthin a rule */
+  padding: 5px;
+}
+
+
+body > * {
+  
+}
+```
+
+Output:
+```
+TOKEN [ 'root', '\n' ]
+TOKEN [ 'rule_start', 'div {' ]
+TOKEN [ 'rule', '\n  background: red;\n' ]
+TOKEN [ 'rule_end', '}' ]
