  channel: 'general',
  from: 'Thursday, September 15th 2016, 12:00 am',
  to: 'Saturday, October 1st 2016, 12:00 am',
  writeFolder: 'C:\\somePath',
  filename: 'archive_general__20160915-20161001.xml',
  messages: 155,
  files: 7,
  archivePath: 'C:\\somePath\\archive_trades__20160915-20161001.zip',
  archiveFile: 'archive_general__20160915-20161001.zip'
}

Note about Google Chrome

Chrome does not allow XSL styling of local XML files. See: http://stackoverflow.com/questions/2981524/how-can-i-make-xslt-work-in-chrome

Workarounds:

1. Use another browser (IE and FF work fine)
2. Upload the generated archive to a web host
