  //==========================
  // The following line declares how long to wait before reloading the RSS feed. 
  // Keep in mind, many sites discourage people from pulling its feed more often than 30 minutes.
  // For example, Slashdot.org may ban your server if it tries to load the rss feed too often.
  
  // You may change the below line.
  //==========================

  $minutes = 30; //How often to update the image. 0 indicates that image updates every time it is called (heavy strain on bandwidth & server)
 
  //==========================
  // The next line is what directory to dump the htm files generated by this script.
  // It should be relative to the location of this script, and it *MUST* have a trailing slash if it's a seperate dir.
  // If you want the files to be dumped in the same dir as this script, set it to ""

  // You may change the next line
  //==========================

  //==========================
  // The settings below are for advanced headline truncation.
  
  // $default_trunc is how many characters to cut off at, 
  //                the default is FALSE, which wont truncate
  //                at all. 
  
  //                You may use $trunc when calling this script
  //                to define the truncation for specific feeds
  
  // $default_delim is what character to cut off the headline at
  //                for example, if your headlines contain useless
  //                data at the end, like "(via Reuters)", setting
  //                the delimiter to "(" will stop that from showing.
