From the developer:
ILMerge is a utility that can be used to merge multiple .NET assemblies into a single assembly.
ILMerge takes a set of input assemblies and merges them into one target assembly. The first assembly in the list of input assemblies is the primary assembly. When the primary assembly is an executable, then the target assembly is created as an executable with the same entry point as the primary assembly.
