// extend String objects to do ucFirst() like Perl
String.prototype.ucFirst = function () {
  return this.substr(0,1).toUpperCase() +
    this.substr(1,this.length);
}

// extend String objects to do reverse()
String.prototype.reverse = function () {
  var tmp = this.split('');
  tmp.reverse();
  return tmp.join('');
}

// snip whitespace off front and back of string
String.prototype.snip = function () {
  return this.replace(/^\s+|\s+$/g, '');
