    if ( process.platform === 'win32' ) {
      url = url.replace( /\\/g, '/' );
    }

    try {
      file.contents = new Buffer( wrap( file, url ));
    } catch ( err ) {
      this.emit( 'error', new gutil.PluginError( 'gulp-partial', err ));
    }

    this.push( file );
    cb();
  });
}

module.exports = partial;

if few ppl like it, i'll turn it into a proper gulp plugin :-)
