           Summary: missing <config> element in sites.xml causes extremely
                    useless error message
           Product: Swift
           Version: unspecified
          Platform: PC
        OS/Version: Mac OS
            Status: NEW
          Severity: normal
          Priority: P2
         Component: General
        AssignedTo: benc at hawaga.org.uk
        ReportedBy: benc at hawaga.org.uk
                CC: swift-devel at ci.uchicago.edu


Omitting <config> and using <pool> at the top level in sites.xml causes the
following error message on the console:

$ swift examples/first.swift 
Ex098
java.lang.NullPointerException

[further stack trace omitted]

This could be made much more helpful (at least, it should indicate a problem
with sites.xml).
