Merge Examples
This section illustrates an example of running Merge which involves these three
steps:
1. Compiling three .java files to produce .class files as a source for the signature
files used in the example
2. Running the Setup command on each .class file to produce its signature file
3. Using Merge to combine the files and see the results.
