This can be either very simple or very hard depending on the level of
integration that you want to achieve.

On the simple end of the spectrum you might have a pre-processor that
handles the regions of HSPL and produces a new C# file that is later
compiled by the C# compiler.

On the other end of the spectrum, you might actually want to consider
extending the Mono C# compiler and instead of doing a simplistic
macro-processing job, you could probably provide integration between the
two worlds.
