The Subversion SCM system is modeled like this, at least the library
interface part. (I don't know if it uses exceptions.) The CLI version of
the SVN client simply calls the SVN libraries. If a GUI program decides to
screen-scrape the CLI tool instead of using the libraries, it's probably
doing something wrong.
