[GUI programs of CLI tools act wonky in passing information either way between the GUI and CLI layers because of problems in model mismatch or screen scraping....]
IMO this is one of the reasons that Linux has such a hard time approaching real joe-nonhacker-friendliness. The answer, of course, is to have the command-line tools and the GUIs use libraries with strongly-typed interfaces and well-defined exceptions. But who has time for that? :) [TRUNCATE]
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.
Which CLI version of the SVN client? There are lots ;-)
If a GUI program decides to screen-scrape the CLI tool instead of using the libraries, it's probably doing something wrong.
