Failed to download the package from http%3A%2F%2Fwww.klayout.org%2Fsvn-public%2Fklayout-resources%2Ftrunk%2Fexamples.
There needs to be a file called 'grain.xml' below this URL. It needs to have the XML format of a KLayout package definition file.
This URL will be used for the package file: http%3A%2F%2Fwww.klayout.org%2Fsvn-public%2Fklayout-resources%2Ftrunk%2Fexamples/grain.xml.
