[MonoDevelop] Custom Build

[Clint Fairchild]

I'd like to add the functionality to MD to execute arbitrary commands to
build a project, so I can build projects that include both C and C# code
from within the IDE.  I haven't worked on MD before, so I'm not sure
what the best way to go about it is.  I thought of some different ways
to do this:

1: Make an addin for a new project type.

2: Make an addin that adds steps to a C# project.

3: Hack the functionality into the existing project properties.

What would be best?  Or is there a better way that I didn't think of?

Thanks,
Clint
