+# inertia
+
+inertia is a VERY simple static file server for nodejs. so simple, it's retarded.
+
+## Installation
+
+```
+   npm install inertia
+
+```
+
+## Requiring
+
+```javascript
+
+   var inertia = require( 'inertia' );
+
+```
+
+## Usage
+
+```javascript
+
+   var static = inertia.createHandler();
+
+   static.encoding       = 'iso-8859-1';                     // set character encoding
+   static.useCache       = false|true;                       // turn off/ on in-memory caching
+   static.useCompression = false|true;                       // turn off/ on compression
+
+   static.addFileHandler( /^static\..*\.(gif|jpe?g|png)$/i ) // regexp file handler
+          .addFileHandler( 'foo', 'application/foo' )        // add a custom file type with a custom mime type
+          .addFileHandler( 'html' );                         // add a standard file type, common mime types are handled internally
+
+   static.addDirHandler( './lib' );                          // serve all files from a specific directory
+
+   static.compress( 'css', 'html', 'js', 'json', 'txt' );    // compress (using deflate) files with specific extensions
+
+   static.maxAge( 'css', 'js'  60 * 60 * 24 )                // add max-age Cache-Control headers for specific extensions
+         .maxAge( 'html',      60 * 60 )
+
+   http.createServer( function( req, res ) {
+      if ( static.serve( req, res ) ) return;
+
+      // otherwise, do something else...
+   } ).listen( '8080' );
