Re: [nant-dev] NAnt on linux...

OK then the problem is in XmlTextREader probably. It passes back thru 
baseURI exactly what you pass in doc.Load
so :
mono UriTest.exe test.xml
Uri: test.xml

mono UriTest.exe ../test.xml
Uri: ../test.xml

mono UriTest.exe /home/ianm/foo/test.xml
Uri: /home/ianm/foo/test.xml

it could be a bit smarter.
