Probobly not to where you are executing msbuild from. If the path is relative to where you MSBuild file is, try to concat the relative path to the MSBuild File path.
Make sure that you are writing correctly the relative path "..\dll\Gallio.MSBuildTasks. Dll". I've tried this and I had no problems in specifying relative paths to my dll's.
If the path is not correct you should get an error stating this when you run the build file. If it won't work you can post the error that you get when you use the relative path.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
