wouldn't it be better to have something similar to the Ant concat task
(http://ant.apache.org/manual/CoreTasks/concat.html), which allows files to
be concatenated or the tasks inline text be appended (or overwritten) to the
destination file ?
If no destination file is specified, output will be written to the build
log. It should be pretty easy to port to .NET.
