Writing Custom NAnt Tasks

"Our product is made up of both managed and unmanaged code, third party libraries with .NET wrappers, code that sometimes differs from .NET 1.1 to .NET 2.0 (both x86 and x64) and a slew of other complications. In addition to that and the multiple systems it takes to put it all together, there comes a time where a custom solution might be the best way to do things. In the world of NAnt scripts, this can come in many forms, but personally I prefer to stay away from batch files and calls to the command-line. In my mind, the most elegant option is to write a NAnt task." [Sample Code included]
