  This XSL transforms the Windows Timezone list from the Unicode CLDR to a plist
  which is consumable by CoreFoundation.  You need to fetch the latest mapping
  from the Unicode consortium from:
    https://unicode.org/repos/cldr/trunk/common/supplemental/windowsZones.xml
  The XSL can be applied to this data via the `xsltproc` command.
  Running
    `xsltproc &dash;&dash;novalid WindowsOlsonDatabase.xsl windowsZones.xml`
  will generate the mapping plist.
